BACKGROUND OF THE INVENTION
Field of the Invention
The present invention is directed generally to devices configured
to generate hydrogen gas and, more particularly, to devices that generate
hydrogen gas by performing electrolysis on water.
Description of the Related Art
Hydrogen is considered a clean energy source. Unfortunately,
many current methods of generating hydrogen for use as a fuel source have not
been cost effective. Further, many current methods of generating hydrogen are
not capable of generating a sufficient amount of hydrogen at a desired rate.

DETAILED DESCRIPTION OF THE INVENTION
Figure 1 is a block diagram of a system 100 that includes a
hydrogen generator 106. The hydrogen generator 106 is connected to an
electrical power controller 108 by electrical conductors 110 (e.g., wires).
The
power controller 108 may be configured to deliver direct current ("DC") to the
hydrogen generator 106. As shown in Figure 3, the power controller 108 has a
positive terminal T+ and a negative terminal T-. The power controller 108 is
configured to determine a voltage of the current delivered to the hydrogen
generator 106. Thus, the power controller 108 is configured to deliver current
having an adjustable voltage. The power controller 108 is connected to or
includes a power source 109 that may be implemented as a battery or a power
converter configured to receive alternating current ("AC") from an AC source
(e.g., a conventional wall socket) and convert the AC to DC.
The hydrogen generator 106 is connected to a water source 112
(e.g., a water tank) by one or more water lines 114. The hydrogen
generator 106 is configured to receive water 116 from the water source 112.
Referring to Figure 2, the hydrogen generator 106 uses electrolysis to split
water molecules (H20) 117 (in the water 116) into hydrogen (H) atoms 118 and
3
CA 03111016 2021-02-26
WO 2020/044207
PCT/IB2019/057170
oxygen (0) atoms 119. Next, two of the hydrogen atoms 118 combine to form
hydrogen gas (H2) 120, and two of the oxygen (0) atoms 119 combine to form
oxygen gas (02) 121.
Referring to Figure 1, the water 116 may include a catalyst 122,
such as potassium hydroxide (KOH). By way of a non-limiting example, the
water source 112 may be configured to hold about 5 liters of water. About 600
grams of the catalyst 122 (e.g., KOH) may be added to the 5 liters of water.
In
other words, about 120 grams of the catalyst 122 may be added per liter of
water.
The hydrogen gas 120 (see Figure 2) produced by the hydrogen
generator 106 may be conducted (e.g., by one or more hydrogen gas lines 128)
to a hydrogen reservoir 130. In some embodiments, the water source 112 may
also function as the hydrogen reservoir 130. The hydrogen gas 120
(see Figure 2) may be conducted (e.g., by one or more gas lines 136) from the
hydrogen reservoir 130 to an optional gas control system 132 that is
configured
to transfer the hydrogen gas 120 to a hydrogen consuming process and/or
device 134. If the optional gas control system 132 has been omitted, the gas
line(s) 136 may conduct the hydrogen gas 120 (see Figure 2) directly to the
hydrogen consuming process and/or device 134. Alternatively, the hydrogen
gas 120 (see Figure 2) may remain in the hydrogen reservoir 130 for later use.
The oxygen gas 121 (see Figure 2) produced by the hydrogen
generator 106 may be conducted (e.g., by the hydrogen gas line(s) 128 and/or
one or more oxygen gas lines 124) to an oxygen reservoir 126. In some
embodiments, the hydrogen reservoir 130 and/or the water source 112 may
function as the oxygen reservoir 126. The oxygen gas 121 (see Figure 2) may
be conducted (e.g., by one or more oxygen gas lines 138) from the oxygen
reservoir 126 to the optional gas control system 132 or the hydrogen
consuming process and/or device 134. Alternatively, the oxygen gas 121
(see Figure 2) may be vented into the surrounding environment instead of being
conducted to the oxygen reservoir 126. By way of yet another non-limiting
example, the oxygen gas 121 (see Figure 2) may remain in the oxygen
reservoir 126 for later use.

The hydrogen generator 106 includes one or more cells 140. In
the example illustrated, the hydrogen generator 106 includes cells 140A
and 140B, which are substantially identical to one another. However, the
hydrogen generator 106 may include any number of cells each like the
cells 140A and 140B. For example, Figure 3 illustrates an implementation in
which the hydrogen generator 106 includes only the cell 140A. When the
hydrogen generator 106 includes more than one cell, such as the cells 140A
and 140B, the electrical conductors 110 may connect the power controller 108
to the cells in series. The water source 112 may be connected to the cells in
parallel.
In the embodiment illustrated in Figure 3, the water source 112
functions as both the hydrogen reservoir 130 and the oxygen reservoir 126.
Thus, the hydrogen gas line(s) 128 connect the hydrogen generator 106 to the
water source 112 and conduct both the hydrogen gas 120 (see Figure 2) and
the oxygen gas 121 (see Figure 2) into the water source 112. Then, the gas
line(s) 136 conduct both the hydrogen gas 120 (see Figure 2) and the oxygen
gas 121 (see Figure 2) from the water source 112 to the optional gas control
system 132 (see Figure 1) or the hydrogen consuming process and/or
device 134 (see Figure 1). In the embodiment illustrated in Figure 3, the
cell 140A includes a plurality of plates 142, a plurality of seals 144
(see Figures 4A, 5, and 11), a first end cap 146, a second end cap 148, a
plurality of ties 152, and an optional plurality of fasteners 154 (e.g.,
nuts).
Referring to Figure 6, each of the plates 142 has a generally
rectangular outer shape 158 surrounding a body portion 160. The generally
rectangular outer shape 158 has a length L1 (e.g., about 10 cm) and a height
H1 (e.g., about 15 cm). The generally rectangular outer shape 158 has four
corners C1-C4 and four edges E1-E4. The corners C2-C4 are each notched or
cutout to define cutouts 161B-161D. The cutouts 161B-161D may each have a
quarter-circle shape centered at the corners C2-C4, respectively. By way of a
non-limiting example, when the cutouts 161B-161D have a quarter-circle shape,
they may each have a radius of about 1.0 cm. In the embodiment illustrated,
each of the plates 142 is generally planar.

WO 2020/044207 PCT/IB2019/057170
In the embodiment illustrated, the edges El and E3 are shorter
than the sides E2 and E4. The edges El -E4 each have cutouts formed therein.
The shorter edges El and E3 each have two cutouts 162A and 162B, and the
longer edges E2 and E4 each have three cutouts 163A-163C. Each of the
cutouts 162A-163C may have a semicircular shape centered on the edge in
which the cutout is formed. By way of a non-limiting example, each of the
cutouts 162A-163C may have a radius of about 0.5 cm.
The following are exemplary minimum distances defining
positions of the cutouts 162A and 162B formed in each of the edges El and E3.
A minimum distance between the cutout 162A and the cutout 162B may be
about 3 cm. A minimum distance between the cutout 162A formed in the
edge El and the corner C2 may be about 2.5 cm. Similarly, a minimum
distance between the cutout 162A formed in the edge E3 and the corner C3
may be about 2.5 cm. A minimum distance between the cutout 162B formed in
the edge El and the corner Cl may be about 2.5 cm. Similarly, a minimum
distance between the cutout 162B formed in the edge E3 and the corner C4
may be about 2.5 cm.
The following are exemplary minimum distances defining
positions of the cutouts 163A-163C formed in each of the edges E2 and E4. A
minimum distance between the cutout 163A and the cutout 163B may be about
3 cm. A minimum distance between the cutout 163B and the cutout 163C may
be about 3.2 cm. A minimum distance between the cutout 163A formed in the
edge E2 and the corner C2 may be about 3 cm. Similarly, a minimum distance
between the cutout 163A formed in the edge E4 and the corner Cl may be
about 3 cm. A minimum distance between the cutout 163C formed in the
edge E2 and the corner C3 may be about 2.8 cm. Similarly, a minimum
distance between the cutout 163C formed in the edge E4 and the corner C4
may be about 2.8 cm.
The body portion 160 includes a plurality of through-holes 170. A
first embodiment of the plates 142 is illustrated in Figures 3-10. Referring
to
Figure 6, in the first embodiments, the through-holes 170 include five
through-holes 171-175. By way of a non-limiting example, each of the
through-holes 171-175 may have a circular shape with a radius of about
6
CA 03111016 2021-02-26
WO 2020/044207 PCT/IB2019/057170
0.5 cm. The through-holes 171-174 are arranged linearly in a series that is
substantially parallel with the edges El and E3. The through-holes 171-174 are
positioned nearer the edge E3 than the edge El. The through-holes 171
and 172 are spaced apart by a minimum distance of about 0.8 cm. The
through-holes 172 and 173 are spaced apart by a minimum distance of about
0.8 cm. The through-holes 173 and 174 are spaced apart by a minimum
distance of about 0.8 cm. The through-holes 171-174 are spaced apart by a
minimum distance of about 1.6 cm from the edge E3. The through-hole 171 is
spaced apart by a minimum distance of about 2.0 cm from the edge E2. The
through-hole 174 is spaced apart by a minimum distance of about 1.6 cm from
the edge E4. The through-hole 175 is positioned nearer the edge El than the
edge E3. In the embodiment illustrated, the through-hole 175 is spaced apart
by a minimum distance of about 2.2 cm from each of the edges El and E4.
The body portion 160 may have an optional through-hole 178
positioned closer to the corner Cl than the through-hole 175. By way of a
non-limiting example, the through-hole 178 may have a circular shape with a
radius of about 0.2 cm. The through-hole 178 may be spaced apart by a
minimum distance of about 0.3 cm from each of the edges El and E4.
While exemplary dimensions are provided above, through
application of ordinary skill in the art to the present teachings, the plates
142
may be sized or scaled appropriately for a desired application. For example,
smaller plates may be used if less hydrogen is desired. Similarly, larger
plates
or multiple cells may be used if more hydrogen is desired. Each of the
plates 142 is constructed from a substantially electrically conductive
material.
By way of a non-limiting example, each of the plates 142 may be constructed
from stainless steel and the like.
Referring to Figure 5, the plates 142 are substantially parallel with
one another and arranged in a series. The plates 142 include one or more
positive plates 101 (see Figure 7), one or more negative plates 102
(see Figure 8), and one or more neutral plates positioned in between each
adjacent pair of positive and negative plates. For example, the neutral
plate(s)
may include a first neutral plate 103 (see Figure 9) and a second neutral
plate 104 (see Figure 10), which may alternate inside the cell 140A

WO 2020/044207 PCT/IB2019/057170
(see Figures 1 and 3-46). Referring to Figure 7, the oxygen atoms 119
(see Figure 2) collect along each of the positive plate(s) 101 and a first
side 180
or a second side 182 (see Figures 5, 8, 10, 13, 15, 18, and 20) of any of the
first and second neutral plates 103 (see Figure 9) and 104 (see Figure 10)
facing the positive plate 101. Referring to Figure 8, the hydrogen atoms 118
(see Figure 2) collect along each of the negative plate(s) 102 and the first
side 180 (see Figures 5-7, 9, 12, 14, 17, and 19) or the second side 182 of
any
of the first and second neutral plates 103 (see Figure 9) and 104
(see Figure 10) facing the negative plate 102.
Referring to Figure 5, in the embodiment illustrated, the
plates 142 include two positive plates 142-PA and 142-PB (each like the
positive plate 101 illustrated in Figure 7), two negative plates 142-NA
and 142-NB (each like the negative plate 102 illustrated in Figure 8), six
first
neutral plates 142-N1, 142-N3, 142-N5, 142-N7, 142-N9, and 142-N11
(each like the first neutral plate 103 illustrated in Figure 9), and six
second
neutral plates 142-N2, 142-N4, 142-N6, 142-N8, 142-N10, and 142-N12
(each like the second neutral plate 104 illustrated in Figure 10). Inside the
cell 140A (see Figures 1 and 3-46), the plates 142 may be arranged in the
following predetermined order from the first end cap 146 (see Figures 3-46,
16,
23, and 24) to the second end cap 148 (see Figures 3-46, 16, 23, and 24):
positive plate 142-PA, first neutral plate 142-N1, second neutral plate 142-
N2,
first neutral plate 142-N3, second neutral plate 142-N4, negative plate 142-
NA,
first neutral plate 142-N5, second neutral plate 142-N6, first neutral
plate 142-N7, second neutral plate 142-N8, positive plate 142-PB, first
neutral
plate 142-N9, second neutral plate 142-N10, first neutral plate 142-N11,
second
neutral plate 142-N12, and negative plate 142-NB.
A pattern may be formed (e.g., etched, scratched, laser cut,
embossed, printed, etc.) on the first and/or second sides 180 and 182 of each
of the plates 142. The patterns may be configured to help direct water flow
and/or gas flow through the cell 140A (see Figures 1 and 3-46). The patterns
may be configured to generate a desired volume of hydrogen gas at a desired
rate. The patterns may help induce a desired current flow in the water 116
(see Figures 1-3). The patterns may help direct the hydrogen and oxygen
8

gases 120 and 121 (see Figure 2) through the through-holes 171-175
(see Figures 6-10) and toward the second end cap 148 (see Figures 3-4B, 16,
23, and 24).
As mentioned above, each of the positive plates 142-PA
and 142-PB (see Figures 4A and 5) may be implemented as the positive
plate 101 (see Figure 7). Referring to Figure 7, the positive plate 101
includes
a positive pattern 190 formed on its first side 180. As illustrated in Figure
7, the
positive plate 101 is oriented with its corner Cl positioned in an upper left
position when the first side 180 is facing forwardly (or toward the first end
cap
146 illustrated in Figures 3-4B, 16, 23, and 24). The positive pattern 190
includes four lines 191-194 that extend from the through-holes 171-174,
respectively, to the through-hole 175. In the embodiment illustrated, the
lines 191-194 intersect at a point on the edge of the through-hole 175. The
lines 191-194 induce flow toward the through-hole 175 in a first flow
direction
identified by an arrow Al. Each of the lines 191-194 may be formed as a
continuous line or by a plurality of through-holes arranged in a series to
define
the line. The plurality of through-holes may each have a diameter of about
1 millimeter ("mm") to about 2 mm.
As mentioned above, each of the negative plates 142-NA
and 142-NB (see Figures 4A and 5) may be implemented as the negative
plate 102 (see Figure 8). Referring to Figure 8, the negative plate 102
includes
a negative pattern 200 formed on its second side 182. As illustrated in
Figure 8, the negative plate 102 is oriented with its corner Cl positioned in
an
upper right position when the second side 182 is facing forwardly (or toward
the
first end cap 146 illustrated in Figures 3-4B, 16, 23, and 24). The negative
pattern 200 includes four lines 201-204 that extend from the through-holes
171-174, respectively, to the through-hole 175. In the embodiment illustrated,
the lines 201-204 intersect at a point on the edge of the through-hole 175.
The
lines 201-204 induce flow toward the through-hole 175 in a second flow
direction identified by an arrow A2. Each of the lines 201-204 may be formed
as a continuous line or by a plurality of through-holes arranged in a series
to
define the line. The plurality of through-holes may each have a diameter of
about 1 mm to about 2 mm. When the plurality of through-holes are used to
9
CA 03111016 2021-02-26
WO 2020/044207 PCT/IB2019/057170
define the lines 191-194 (see Figure 7) on the first side 180, the plurality
of
through-holes also define the lines 201-204 on the second side 182. Thus, the
positive plate 101 (see Figure 7) and the negative plate 102 may simply be
mirror images of one another.
As mentioned above, each of the first neutral plates 142-N1,
142-N3, 142-N5, 142-N7, 142-N9, and 142-N11 may be implemented as the
first neutral plate 103 (see Figure 9). Referring to Figure 9, the first
neutral
plate 103 includes a first neutral pattern 210 formed on its first side 180.
The
first neutral plate 103 is oriented with its corner Cl positioned in a lower
right
position when the first side 180 is facing forwardly (or toward the first end
cap 146 illustrated in Figures 3-4B, 16, 23, and 24). The first neutral
pattern 210 includes six lines 211-216. The lines 213-216 extend outwardly
from a first intersection point 217. By way of non-limiting examples, the
first
intersection point 217 may be positioned about 2.0 cm above the edge El and
about 4.8 cm away from the edge E4. The lines 215 and 216 extend outwardly
from the first intersection point 217 and form a V-shape. The line 216 extends
from the first intersection point 217 to the through-hole 175. The line 216
may
extend through the through-hole 175 and to the edge E4 or may terminate
between the through-hole 175 and the edge E4. The lines 213 and 214 extend
from the first intersection point 217 to the through-holes 173 and 174,
respectively. The line 215 extends from the first intersection point 217 to a
termination point 218. By way of non-limiting examples, the termination
point 218 may be positioned about 4.5 cm above the edge El and about 1.5 cm
away from the edge E2. The lines 211 and 212 extend from the line 215 to the
through-holes 171 and 172, respectively. The lines 211 and 212 may each be
substantially parallel to the edges E2 and E4. The lines 211-216 induce an
upward flow toward the through-holes 171-174 in a third flow direction
identified
by an arrow A3. The third flow direction may be substantially parallel to the
edges E2 and E4. Each of the lines 211-216 may be formed as a continuous
line or by a plurality of through-holes arranged in a series to define the
line.
The plurality of through-holes may each have a diameter of about 1 mm to
about 2 mm.

As mentioned above, each of the second neutral plates 142-N2,
142-N4, 142-N6, 142-N8, 142-N10, and 142-N12 may be implemented as the
second neutral plate 104 (see Figure 10). Referring to Figure 10, the second
neutral plate 104 includes a second neutral pattern 220 formed on its second
side 182. The second neutral plate 104 is oriented with its corner Cl
positioned
in a lower left position when the second side 182 is facing forwardly (or
toward
the first end cap 146 illustrated in Figures 3-4B, 16, 23, and 24). The second
neutral pattern 220 includes six lines 221-226. The lines 223, 225, and 226
extend outwardly from a second intersection point 227. By way of non-limiting
examples, the second intersection point 227 may be positioned about 2.0 cm
above the edge El and about 4.8 cm away from the edge E4. The lines 225
and 226 extend outwardly from the second intersection point 227 and form a
V-shape. The line 226 extends from the second intersection point 227 to the
through-hole 175. The line 226 may extend through the through-hole 175 and
to the edge E4 or may terminate between the through-hole 175 and the
edge E4. The line 223 extends from the second intersection point 227 to the
through-hole 173. The line 225 extends from the second intersection point 227
to the edge E2. The lines 221 and 222 extend from the line 225 to the through-
holes 171 and 172, respectively. The lines 221 and 222 may each be
substantially parallel to the edges E2 and E4. The line 224 extends from the
line 226 to the through-holes 174. The line 224 intersects the line 226 at a
location between the second intersection point 227 and the through-hole 175.
The lines 221-226 induce an upward flow toward the through-holes 171-174 in
a fourth flow direction identified by an arrow A4. The fourth flow direction
may
be substantially parallel to the edges E2 and E4. Each of the lines 221-226
may be formed as a continuous line or by a plurality of through-holes arranged
in a series to define the line. The plurality of through-holes may each have a
diameter of about 1 mm to about 2 mm. When the plurality of through-holes are
used to define the lines 211-216 (see Figure 7) on the first side 180, the
plurality of through-holes also define the lines 221-226 on the second side
182.
Thus, the first neutral plate 103 (see Figure 9) and the second neutral plate
104
may simply be mirror images of one another.

A first embodiment of the seals 144 is illustrated in Figures 4A, 5,
and 11. In the embodiment illustrated, each of the seals 144 is generally
planar. Referring to Figure 4A, the seals 144 help define a sealed internal
chamber 228 inside the cell 140A. The sealed internal chamber 228 may be
characterized as being an electrolysis chamber because the plates 142 split
the
water (see Figures 1-3) inside the sealed internal chamber 228. Referring to
Figure 11, each of the seals 144 has a peripheral portion 229 that defines an
interior shape 230, which is closed along the peripheral portion 229 of the
seal.
Referring to Figure 5, each of the seals 144 has a front side 231 opposite a
back side 232. The interior shape 230 (see Figures 11 and 21) is open along
both the front and back sides 231 and 232. Referring to Figure 4A, an
interstitial space 234 is defined between each adjacent pair of plates within
the
series of plates 142. One of the seals 144 is positioned within each of the
interstitial spaces 234. For example, one of the seals 144 is positioned in
the
interstitial space 234 defined between the plates 142-PA and 142-N1. The
seals 144 are configured such that the through-holes 171 -1 75 (see
Figures 6-10) of each of the plates 142 are positioned within the interior
shape 230 (see Figures 11 and 21) of any of the seals 144 positioned alongside
the plate. Thus, the interior shapes 230 (see Figures 11 and 21) of the
seals 144 are interconnected inside the cell 140A by one or more of the
through-holes 170 (see Figures 6-10, 12-15, and 17-20) and define the sealed
internal chamber 228.
Referring to Figure 4B, an interstitial space 236 may be defined
between the first end cap 146 and the positive plate 142-PA. One of the
seals 144, identified with reference numeral 144A, may be positioned in the
interstitial space 236. The seal 144A is positioned such that the through-
holes
171-175 (see Figures 6-10) of the positive plate 142-PA are positioned within
the interior shape 230 (see Figures 11 and 21) of the seal 144A. Thus, the
interior shape 230 (see Figures 11 and 21) of the seal 144A may be considered
to be part of the sealed internal chamber 228.
Similarly, an interstitial space 238 may be defined between the
second end cap 148 and the negative plate 142-NB. One of the seals 144,
identified with reference numeral 144B in Figure 5, may be positioned in the
12
CA 03111016 2021-02-26
WO 2020/044207 PCT/IB2019/057170
interstitial space 238. The seal 144B (see Figure 5) is positioned such that
the
through-holes 171-175 (see Figures 6-10) of the negative plate 142-NB are
positioned within the interior shape 230 (see Figures 11 and 21) of the
seal 144B. Thus, the interior shape 230 (see Figures 11 and 21) of the
seal 144B (see Figure 5) may be considered to be part of the sealed internal
chamber 228.
Referring to Figure 4A, the seals 144 are substantially electrically
non-conductive, and electrically isolate the plates 142 from one another.
Thus,
within the cell 140A, current flows between the plates 142 through the
water 116 (see Figures 1-3). By way of a non-limiting example, the seals 144
may each be constructed from styrene-butadiene rubber ("SBR"), silicone, and
the like.
As is apparent to those of ordinary skill in the art, the hydrogen
gas 120 (see Figure 2) will collect along the negative plates 142-NA and 142-
NB and the oxygen gas 121 (see Figure 2) will collect along the positive
plates 142-PA and 142-PB. Referring to Figure 3, the hydrogen and oxygen
gases 120 and 121 (see Figure 2) are both lighter than the water 116 and
collect near the top of the sealed internal chamber 228 (see Figures 4A
and 4B). Additionally, the hydrogen gas 120 (see Figure 2) is lighter than the
oxygen gas 121 (see Figure 2). Thus, the hydrogen gas 120 (see Figure 2)
may collect nearer the top of the sealed internal chamber 228 (see Figures 4A
and 4B) than the oxygen gas 121 (see Figure 2). Each of the flows identified
by
the arrows A1-A4 in Figures 7-10, respectively, may be directed toward the
near the top of the sealed internal chamber 228 (see Figures 4A and 4B).
Referring to Figure 4A, the cell 140A has at least one water inlet,
such as a water inlet 240, through which the water 116 (see Figures 1-3)
enters
the sealed internal chamber 228 of the cell 140A. In the embodiment
illustrated, the water inlet 240 is formed in the first end cap 146. Thus, the
water inlet 240 is in fluid communication with the sealed internal chamber
228.
The water 116 (see Figures 1-3) flows from the water inlet 240 toward the
second end cap 148. The water 116 (see Figures 1-3) flows through the
through-holes 170 (see Figures 6-10, 12-15, and 17-20) in the plates 142 and
into the interior shapes 230 (see Figures 11 and 21) of the seals 144 (see
13
CA 03111016 2021-02-26
WO 2020/044207 PCT/IB2019/057170
Figures 4A, 5, and 11) positioned between each adjacent pair of plates. The
first end cap 146 includes a plurality of through-holes 242 (see Figure 4B)
through which the ties 152 may extend.
The cell 140A has at least one hydrogen outlet, such as a
hydrogen outlet 244, through which the hydrogen gas 120 (see Figure 2) exits
the sealed internal chamber 228 of the cell 140A (e.g., and enters the
hydrogen
gas line(s) 128 illustrated in Figures 1 and 3). In the embodiment
illustrated,
the hydrogen outlet 244 is formed in second end cap 148. Thus, the hydrogen
outlet 244 is in fluid communication with the sealed internal chamber 228. The
hydrogen gas 120 (see Figure 2) flows from the negative plates 142-NA
and 142-NB toward the second end cap 148. Like the water 116 (see
Figures 1-3), the hydrogen gas 120 (see Figure 2) flows through the
through-holes 170 (see Figures 6-10, 12-15, and 17-20) in the plates 142 and
into the interior shapes 230 (see Figures 11 and 21) of the seals 144
positioned
.. between each adjacent pair of plates. By way of a non-limiting example, the
hydrogen outlet 244 may be threaded with 1/4 National Pipe Thread Taper
("NPT") threads configured to receive a 10 mm quick connector. The oxygen
gas 121 (see Figure 2) may exit through the hydrogen outlet 244 or be vented
into the surrounding environment via one or more check valves (not shown)
formed in the second end cap 148. The second end cap 148 includes a
plurality of through-holes 246 (see Figure 4B) through which the ties 152 may
extend. The first and second end caps 146 and 148 are each constructed from
a substantially electrically non-conductive material. By way of a non-limiting
example, the first and second end caps 146 and 148 may be constructed from
plastic (e.g., nylon, acrylonitrile Butadiene Styrene ("ABS"), etc.) and the
like.
Referring to Figure 3, the positive terminal T+ of the power
controller 108 is connected (e.g., by one of the conductors 110) to the
positive
plates 142-PA and 142-PB (see Figures 4A-5). Referring to Figure 4B, in the
embodiment illustrated, an optional positive conductor 250 (e.g., a bolt) is
inserted through the optional through-hole 178 (see Figures 6-10, 12-15,
and 17-20) of the positive plates 142-PA and 142-PB. Referring to Figure 3,
the positive terminal T+ of the power controller 108 is connected (e.g., by
one of
the conductors 110) to the positive conductor 250. Referring to Figure 4A, the
14
CA 03111016 2021-02-26
WO 2020/044207 PCT/IB2019/057170
cutout 161B (see Figure 6) of the negative plates 142-NA and 142-NB prevents
the positive conductor 250 from contacting the negative plates 142-NA
and 142-NB. Similarly, referring to Figure 5, the cutout 161C (see Figure 6)
of
the neutral plates 142-N1, 142-N3, 142-N5, 142-N7, 142-N9, and 142-N11
.. prevents the positive conductor 250 (see Figures 3-4B) from contacting the
neutral plates 142-N1, 142-N3, 142-N5, 142-N7, 142-N9, and 142-N11.
Additionally, the cutout 161D (see Figure 6) of the neutral plates 142-N2,
142-N4, 142-N6, 142-N8, 142-N10, and 142-N12 prevents the positive
conductor 250 (see Figures 3-4B) from contacting the neutral plates 142-N2,
142-N4, 142-N6, 142-N8, 142-N10, and 142-N12.
Referring to Figure 3, the negative terminal T- of the power
controller 108 is connected to the negative plates 142-NA and 142-NB
(see Figures 4A-5). Referring to Figure 4A, in the embodiment illustrated, an
optional negative conductor 252 (e.g., a bolt) is inserted through the
.. through-hole 178 (see Figures 6-10, 12-15, and 17-20) of the negative
plates 142-NA and 142-NB. Referring to Figure 3, the negative terminal T- of
the power controller 108 is connected to the negative conductor 252 (e.g., by
one of the conductors 110). Referring to Figure 4A, the cutout 161B (see
Figure 6) of the positive plates 142-PA and 142-PB prevents the negative
.. conductor 252 from contacting the positive plates 142-PA and 142-PB.
Similarly, referring to Figure 5, the cutout 161D (see Figure 6) of the
neutral
plates 142-N1, 142-N3, 142-N5, 142-N7, 142-N9, and 142-N11 prevents the
negative conductor 252 from contacting the neutral plates 142-N1, 142-N3,
142-N5, 142-N7, 142-N9, and 142-N11. Additionally, the cutout 161C
(see Figure 6) of the neutral plates 142-N2, 142-N4, 142-N6, 142-N8, 142-N10,
and 142-N12 prevents the negative conductor 252 from contacting the neutral
plates 142-N2, 142-N4, 142-N6, 142-N8, 142-N10, and 142-N12.
Referring to Figure 4A, the water 116 (see Figures 1-3) inside the
cell 140A connects the positive plates 142-PA and 142-PB and the negative
plates 142-NA and 142-NB to form a circuit. Referring to Figure 3, the flow of
current through the water 116 causes the water molecules 117 (see Figure 2) to
split into the hydrogen atoms 118 (see Figure 2) and the oxygen atoms 119
CA 03111016 2021-02-26
WO 2020/044207 PCT/IB2019/057170
(see Figure 2). In other words, the electrolysis performed by the cell 140A is
powered by the power controller 108.
Referring to Figure 5, optionally, a first ground conductor (not
shown) may be inserted through the through-hole 178 (see Figures 6-10, 12-15,
and 17-20) of the first neutral plates 142-N1, 142-N3, 142-N5, 142-N7, 142-N9,
and 142-N11. Similarly, a second ground conductor (not shown) may be
inserted through the through-hole 178 (see Figures 6-10, 12-15, and 17-20) of
the second neutral plates 142-N2, 142-N4, 142-N6, 142-N8, 142-N10,
and 142-N12. The first and second ground conductors (not shown) may each
be connected to ground and do not contact either the positive plates 142-PA
and 142-PB or the negative plates 142-NA and 142-NB.
Thus, the cell 140A (see Figures 1 and 3-4B) may be configured
as follows:
1. the positive plate 142-PA oriented with its through-hole 178
(see Figures 6-10, 12-15, and 17-20) positioned top left and
connected to the positive conductor 250 (see Figure 3-4B);
2. the neutral plates 142-N1 to 142-N4 (optionally, the first
neutral plates 142-N1 and 142-N3 may be connected to the
first ground conductor (not shown) and the second neutral
plates 142-N2 and 142-N4 may be connected to the second
ground conductor (not shown));
3. the negative plate 142-NA oriented with its through-hole 178
positioned top right and connected to the negative
conductor 252;
4. the neutral plates 142-N5 to 142-N8 (optionally, the first
neutral plates 142-N5 and 142-N7 may be connected to the
first ground conductor (not shown) and the second neutral
plates 142-N6 and 142-N8 may be connected to the second
ground conductor (not shown));
5. the positive plate 142-PB oriented with its through-hole 178
positioned top left and connected to the positive
conductor 250;
16
CA 03111016 2021-02-26
WO 2020/044207 PCT/IB2019/057170
6. the neutral plates 142-N9 to 142-N12 (optionally, the first
neutral plates 142-N9 and 142-N11 may be connected to the
first ground conductor (not shown) and the second neutral
plates 142-N10 and 142-N12 may be connected to the
second ground conductor (not shown)); and
7. the negative plate 142-NB oriented with its through-hole 178
positioned top right and connected to the negative
conductor 252.
The positive plates 142-PA and 142-PB create an electric arc with
the negative plates 142-NA and 142-NB that is driven by the water 116 (see
Figures 1-3). The neutral plates 142-N1 to 142-N12 create resistance between
the positive plates 142-PA and 142-PB and the negative plates 142-NA
and 142-NB and increase the flow of current (e.g., measured in amperes).
Referring to Figure 4A, in the embodiment illustrated, the ties 152
(e.g., threaded rods) are configured to connect the first and second end
caps 146 and 148 together with the plates 142 and seals 144 positioned
therebetween. The ties 152 extend alongside and substantially perpendicular
to the edges El -E4 (see Figure 6) of the plates 142. Referring to Figure 6,
the
cutouts 162A and 1626 on the edges El and E3 and the cutouts 163A-163C on
the edges E2 and E4 are each configured to receive a portion of a different
one
of the ties 152 (see Figures 3-46). Referring to Figure 4A, the ties 152 may
be
constructed from a substantially electrically non-conductive material or may
be
wrapped in a substantially electrically non-conductive material 153. Thus, the
ties 152 do not conduct electricity between the plates 142. The ties 152 help
prevent the plates 142 from moving inside the cell 140A and help maintain
their
positioning inside the cell 140A. The seals 144 are each positioned inwardly
of
the ties 152, which do not extend through the closed interior shapes 230
(see Figures 11 and 21) of the seals 144.
The ties 152 are configured to compress the seals 144 inside the
cell 140A to help ensure that the water 116 (see Figures 1-3) and/or the
hydrogen gas 120 (see Figure 2) does not leak from the cell 140A. In the
embodiment illustrated, the ties 152 have been implemented as threaded rods
surrounded by the substantially electrically non-conductive material 153. The
17
CA 03111016 2021-02-26
WO 2020/044207 PCT/IB2019/057170
fasteners 154 (e.g., nuts) are threaded onto the ends of the threaded rods
alongside each of the first and second end caps 146 and 148. By tightening the
fasteners 154, sufficient pressure may be applied to the first and second end
caps 146 and 148 to compress the seals 144 and prevent leakage.
As mentioned above, referring to Figure 1, the water 116 may
include the catalyst 122 (e.g., potassium hydroxide), which reacts with the
electricity and increases the flow of current (e.g., measured in amperes).
Referring to Figure 2, increasing the current splits more of the water
molecules 117 into the hydrogen and oxygen atoms 118 and 119. Referring to
Figure 3, by way of a non-limiting example, the cell 140A may be configured to
generate about 1.3 liters per minute of hydrogen gas. Referring to Figure 1,
if
the hydrogen consuming process and/or device 134 requires less hydrogen, the
excess hydrogen may simply be vented to the outside environment. By not
storing the excess hydrogen, the system 100 avoids potential explosion risks
associated with storing hydrogen.
Referring to Figure 4A, in alternate embodiments, different
numbers of neutral plates may be positioned between the positive and negative
plates 101 (see Figure 7) and 102 (see Figure 8) of the cell 140A. For
example, the cell 140A may include fifteen neutral plates and be configured as
follows:
1. a first positive plate (like the positive plate 101 illustrated in
Figure 7);
2. a first neutral plate (like the first neutral plate 103 illustrated
in Figure 9);
3. a second neutral plate (like the second neutral plate 104
illustrated in Figure 10);
4. a third neutral plate (like the first neutral plate 103 illustrated
in Figure 9);
5. a fourth neutral plate (like the second neutral plate 104
illustrated in Figure 10);
6. a fifth neutral plate (like the first neutral plate 103 illustrated
in Figure 9);
18
CA 03111016 2021-02-26
WO 2020/044207 PCT/IB2019/057170
7. a first negative plate (like the negative plate 102 illustrated in
Figure 8);
8. a sixth neutral plate (like the first neutral plate 103 illustrated
in Figure 9);
9. a seventh neutral plate (like the second neutral plate 104
illustrated in Figure 10);
10. an eighth neutral plate (like the first neutral plate 103
illustrated in Figure 9);
11. a ninth neutral plate (like the second neutral plate 104
illustrated in Figure 10);
12. a tenth neutral plate (like the first neutral plate 103 illustrated
in Figure 9);
13. a second positive plate (like the positive plate 101 illustrated
in Figure 7);
14. an eleventh neutral plate (like the first neutral plate 103
illustrated in Figure 9);
15. a twelfth neutral plate (like the second neutral plate 104
illustrated in Figure 10);
16. a thirteenth neutral plate (like the first neutral plate 103
illustrated in Figure 9);
17. a fourteenth neutral plate (like the second neutral plate 104
illustrated in Figure 10);
18. a fifteenth neutral plate (like the first neutral plate 103
illustrated in Figure 9);
19. a second negative plate (like the negative plate 102
illustrated in Figure 8).
Again, the two positive plates (each like the positive plate 101 illustrated
in
Figure 7) create electric arcs with the two negative plates (each like the
negative plate 102 illustrated in Figure 8) that is driven by the water 116
.. (see Figures 1-3). The fifteen neutral plates create resistance between the
positive plates and the negative plates and increase the flow of current.

HIGH-DENSITY EMBODIMENT
Figures 12-15 illustrate second embodiments of the plates 142
(see Figures 3-6, 16, and 23) that may be used to construct a high-density
version of the cell 140A (see Figures 1 and 3-46). The high-density version
may be used to supply hydrogen to a flame consuming a very high number of
calories (e.g., a furnace, an industrial oven, and the like). Oxygen produced
by
the high-density version may be combined with the hydrogen to increase the
heat output of the flame.
In Figures 12-15, the through-holes 170 include only the through-
holes 171 and 175. In other words, the through-holes 172-174 are omitted.
Figures 12-15 illustrate plates 301-304, respectively.
Referring to Figure 12, the positive plate 301 may be used to
construct the cell 140A (see Figures 1 and 3-46) instead and in place of the
positive plate 101 (see Figure 7). The positive plate 301 includes a positive
pattern 310 instead of the positive pattern 190 (see Figure 7). The positive
pattern 310 is formed on the first side 180 of the positive plate 301. The
positive plate 301 is oriented with the corner Cl positioned in the upper left
position when the first side 180 is facing forwardly (or toward the first end
cap 146 illustrated in Figures 3-46, 16, 23, and 24). The positive pattern 310
includes five lines 311-315. The line 311 extends from the through-hole 171 to
the through-hole 175 and the line 312 extends from the through-hole 171 to a
first location near the through-hole 175. The line 315 extends outwardly from
the through-hole 171 in a direction substantially parallel with the edge E3.
The
line 313 extends from the line 315 to a second location near the through-hole
175 and spaced apart from the first location. The line 314 extends from the
line 315 to the edge E4. The lines 311-315 are configured to induce flow
toward the through-hole 175 in a fifth flow direction identified by an arrow
AS.
Each of the lines 311-315 may be formed as a continuous line or by a plurality
of through-holes arranged in a series to define the line. The plurality of
through-holes may each have a diameter of about 1 mm to about 2 mm.
Referring to Figure 13, the negative plate 302 may be used to
construct the cell 140A (see Figures 1 and 3-46) instead and in place of the
negative plate 102 (see Figure 8). The negative plate 302 includes a negative
CA 03111016 2021-02-26
WO 2020/044207 PCT/IB2019/057170
pattern 320 instead of the negative pattern 200 (see Figure 8). The negative
pattern 320 is formed on the second side 182 of the negative plate 302. The
negative pattern 320 is oriented with the corner Cl positioned in the upper
right
position when the second side 182 is facing forwardly (or toward the first end
cap 146 illustrated in Figures 3-4B, 16, 23, and 24). The negative pattern 320
includes five lines 321-325. The line 321 extends from the through-hole 171 to
the through-hole 175 and the line 322 extends from the through-hole 171 to a
first location near the through-hole 175. The line 325 extends outwardly from
the through-hole 171 in a direction substantially parallel with the edge E3.
The
line 323 extends from the line 325 to a second location near the
through-hole 175 and spaced apart from the first location. The line 324
extends
from the line 325 to the edge E4. Each of the lines 321-325 may be formed as
a continuous line or by a plurality of through-holes arranged in a series to
define
the line. The plurality of through-holes may each have a diameter of about 1
mm to about 2 mm. The lines 321-325 are configured to induce flow toward the
through-hole 175 in a sixth flow direction identified by an arrow A6. When the
plurality of through-holes are used to define the lines 311-315 (see Figure
12)
on the first side 180, the plurality of through-holes also define the lines
321-325
on the second side 182. Thus, the positive plate 301 (see Figure 12) and the
negative plate 302 may simply be mirror images of one another.
Referring to Figure 14, the first neutral plate 303 may be used to
construct the cell 140A (see Figures 1 and 3-4B) instead and in place of the
first
neutral plate 103 (see Figure 9). The first neutral plate 303 includes a first
neutral pattern 330 instead of the first neutral pattern 210 (see Figure 9).
The
first neutral pattern 330 is formed on the first side 180 of the first neutral
plate 303. The first neutral plate 303 is oriented with the corner Cl
positioned
in the lower right position when the first side 180 is facing forwardly (or
toward
the first end cap 146 illustrated in Figures 3-4B, 16, 23, and 24). The first
neutral pattern 330 includes three lines 331-333. The line 331 extends from
the
through-hole 171 to the through-hole 175. The line 333 extends inwardly from
the edge E4 in a direction substantially parallel with the edge El. The line
333
terminates near the through-hole 175. The line 332 extends from the line 333
to the edge E2 or to a location near the through-hole 175. The lines 331-333
21

are configured to induce flow toward the through-hole 171 in a seventh flow
direction identified by an arrow A7. Each of the lines 331-333 may be formed
as a continuous line or by a plurality of through-holes arranged in a series
to
define the line. The plurality of through-holes may each have a diameter of
about 1 mm to about 2 mm.
Referring to Figure 15, the second neutral plate 304 may be used
to construct the cell 140A (see Figures 1 and 3-4B) instead and in place of
the
second neutral plate 104 (see Figure 10). The second neutral plate 304
includes a second neutral pattern 340 instead of the second neutral pattern
220
(see Figure 10). The second neutral pattern 340 is formed on the second
side 182 of the second neutral plate 304. The second neutral plate 304 is
oriented with the corner Cl positioned in the lower left position when the
second side 182 is facing forwardly (or toward the first end cap 146
illustrated in
Figures 3-4B, 16, 23, and 24). The second neutral pattern 340 includes three
lines 341-343. The line 341 extends from the through-hole 171 to the through-
hole 175. The line 343 extends inwardly from the edge E4 in a direction
substantially parallel with the edge El. The line 343 terminates near the
through-hole 175. The line 342 extends from the line 343 to the edge E2 or to
a
location near the through-hole 171. The lines 341-343 are configured to induce
flow toward the through-hole 171 in an eighth flow direction identified by an
arrow A8. Each of the lines 341-343 may be formed as a continuous line or by
a plurality of through-holes arranged in a series to define the line. The
plurality
of through-holes may each have a diameter of about 1 mm to about 2 mm.
When the plurality of through-holes are used to define the lines 331-333
(see Figure 14) on the first side 180, the plurality of through-holes also
define
the lines 341-343 on the second side 182. Thus, the first neutral plate 303
(see Figure 9) and the second neutral plate 304 may simply be mirror images of
one another.
Each of the flows identified by the arrows A5-A8 in Figures 12-15,
respectively, may be directed toward the near the top of the sealed internal
chamber 228 (see Figures 4A and 4B). In the positive and negative plates 301
and 302, the through-hole 171 may be characterized as being an entrance or
inlet and the through-hole 175 may be characterized as being an exit or
outlet.
22
CA 03111016 2021-02-26
WO 2020/044207 PCT/IB2019/057170
The fifth and sixth flow directions (identified by the arrows A5 and A6) each
flow
from the inlet (the through-hole 171) toward the outlet (the through-hole
175).
In the first and second neutral plates 303 and 304, the through-hole 175 may
be
characterized as being an entrance or inlet and the through-hole 171 may be
characterized as being an exit or outlet. The seventh and eighth flow
directions
(identified by the arrows A7 and A8) each flow from the inlet (the
through-hole 175) toward the outlet (the through-hole 171). Referring to
Figures 12-15, when the plates 301-304 are used to construct the cell 140A
(see Figures 1 and 3-46), the flows induced by the fifth, sixth, seventh, and
eighth flow directions cause the water 116 (see Figures 1-3), the hydrogen
gas 120 (see Figure 2), and/or the oxygen gas 121 (see Figure 2) to zig-zag
through the cell 140A. Thus, fewer ones of the through-holes 170 are needed
to create the desired flows.
LOW-DENSITY EMBODIMENT
Figure 16 is a perspective view of a cell 350 that is a low-density
version of the cell 140A (see Figures 1 and 3-46). The cell 350 may be used to
supply hydrogen to a low-density application, such as a flame consuming a low
number of calories (e.g., a residential oven, a lamp, and the like). Oxygen
produced by the low-density version may be vented to the atmosphere. Like
the cell 140A (see Figures 1 and 3-46), the cell 350 includes the plates 142
but
the seals 144 are replaced with seals 352 (see Figures 21 and 23) and
membranes 354 (see Figure 22). In the embodiment illustrated, the water
inlet 240 (see Figures 4A and 46), the hydrogen outlet 244 (see Figures 4A,
46, 23, and 24), and a separate oxygen outlet 362 (see Figures 23 and 24) are
formed in the second end cap 148. In alternate embodiments, the second end
cap 148 may include two or more separate water inlets that are each like the
water inlet 240 (see Figures 4A and 46) and connected to the water source 112
(see Figures 1 and 3) by the water line(s) 114 (see Figures 1 and 3). In
alternate embodiments, the first end cap 146 may include the water inlet 240
(see Figures 4A and 46) or two or more separate water inlets that are each
like
the water inlet 240 and connected to the water source 112 (see Figures 1
and 3) by the water line(s) 114 (see Figures 1 and 3). Optionally, referring
to
23
CA 03111016 2021-02-26
WO 2020/044207
PCT/IB2019/057170
Figure 23, the hydrogen outlet 244 may be positioned above the oxygen
outlet 362. In the embodiment illustrated, the hydrogen outlet 244 and the
oxygen outlet 362 are spaced apart from one another and arranged side-by-
side.
Referring to Figure 16, fittings 364-368 may be connected to the
water inlet 240 (see Figures 4A and 4B), the hydrogen outlet 244 (see
Figures 4A, 4B, 23, and 24), and the oxygen outlet 362 (see Figures 23 and
24), respectively. The fitting 364 is configured to be coupled to the water
line(s) 114 (see Figures 1 and 3) and to supply the water 116 (see Figures 1-
3)
received therethrough from the water source 112 (see Figures 1 and 3) to a
sealed interior 370 (see Figures 23 and 24) of the cell 350. The fitting 366
is
configured to be coupled to the hydrogen gas line(s) 128 (see Figures 1 and 3)
and to conduct the hydrogen gas 120 (see Figure 2) produced by the cell 350 to
the hydrogen reservoir 130 (see Figure 1). The fitting 368 is configured to be
coupled to the oxygen gas line(s) 138 (see Figure 1) and to vent the oxygen
gas 121 (see Figure 2) produced by the cell 350 to the atmosphere.
Figures 17-20 illustrate plates 401-404, respectively, that together
are a third embodiment of the plates 142 (see Figures 3-6, 16, and 23) and may
be used to construct the cell 350 (see Figures 16, 23, and 24). As shown in
Figures 17-20, none of the plates 401-404 includes a pattern of lines.
In Figures 17-20, the through-holes 170 include only the
through-holes 171, 174, 175, and 176. In other words, the through-holes 172
and 173 are omitted. The through-hole 171 may be positioned directly below
the through-hole 176 and directly across from the through-hole 174. The
through-hole 175 may be positioned directly above the through-hole 174 and
directly across from the through-hole 176. Thus, the through-holes 171, 174,
175, and 176 may be positioned at corners of rectangular shape.
Referring to Figure 17, the positive plate 401 is oriented with its
corner Cl positioned in the upper left position when the first side 180 is
facing
forwardly (or toward the first end cap 146 illustrated in Figures 3-4B, 16,
23,
and 24). A flow may be induced along the first side 180 toward the through-
hole 175 in a ninth flow direction identified by an arrow A9. Referring to
Figure 3, the positive conductor 250 (e.g., a bolt) may be inserted through
the
24
CA 03111016 2021-02-26
WO 2020/044207
PCT/IB2019/057170
through-hole 178 of the positive plate 401 (see Figure 17) and connected
(e.g.,
by one of the conductors 110) to the positive terminal T+ of the power
controller 108. In this manner, the positive plate 401 (see Figure 17) may be
charged. Alternatively, one of the conductors 110 may direct couple the
positive plate 401 (see Figure 17) to the positive terminal T+ of the power
controller 108.
Referring to Figure 18, the negative plate 402 is oriented with the
corner Cl positioned in the upper right position when the second side 182 is
facing forwardly (or toward the first end cap 146 illustrated in Figures 3-4B,
16,
23, and 24). A flow may be induced along the second side 182 toward the
through-hole 175 in a tenth flow direction identified by an arrow A10.
Referring
to Figure 3, the negative conductor 252 (e.g., a bolt) may be inserted through
the through-hole 178 of the negative plate 402 (see Figure 18 and 23) and
connected (e.g., by one of the conductors 110) to the negative terminal T- of
the power controller 108. In this manner, the negative plate 402 (see Figure
18
and 23) may be charged. Alternatively, one of the conductors 110 may direct
couple the negative plate 402 (see Figure 18 and 23) to the negative terminal
T- of the power controller 108.
Referring to Figure 19, the first neutral plate 403 is oriented with
the corner Cl positioned in the lower right position when the first side 180
is
facing forwardly (or toward the first end cap 146 illustrated in Figures 3-4B,
16,
23, and 24). A flow may be induced along the first side 180 toward the through-
hole 171 in an eleventh flow direction identified by an arrow A11.
Referring to Figure 20, the second neutral plate 404 is oriented
with the corner Cl positioned in the lower left position when the second side
182 is facing forwardly (or toward the first end cap 146 illustrated in
Figures 3-4B, 16, 23, and 24). A flow may be induced along the second
side 182 toward the through-hole 171 in a twelfth flow direction identified by
an
arrow Al2.
Referring to Figure 21, the seals 352 are substantially similar to
the seals 144 (see Figures 4A, 5, and 11). Thus, each of the seals 352
includes the peripheral portion 229 that defines the interior shape 230, which
is
closed along the peripheral portion 229 of the seal. Each of the seals 352
also
CA 03111016 2021-02-26
WO 2020/044207 PCT/IB2019/057170
has the front side 231 opposite the back side 232 (see Figures 5, 11, and 24).
Further, each of the seals 352 may be generally planar. However, the
seals 352 differ from the seals 144 (see Figures 4A, 5, and 11) because each
of
the seals 352 include first and second barriers 410 and 412 that define first
and
second sealed regions 420 and 422, respectively, within the interior shape
230.
The first sealed region 420 is sealed by the first barrier 410 and the
peripheral
portion 229. The second sealed region 422 is sealed by the second barrier 412
and the peripheral portion 229. The first and second sealed regions 420
and 422 are positioned to isolate two of the through-holes 170 (see
Figures 6-10, 12-15, and 17-20) of each of the plates 401-404 (see
Figures 17-20, respectively) from a remainder 424 of the interior shape 230.
Figure 22 illustrates one of the membranes 354. Each of the
membranes 354 may be generally planar. As shown in Figure 22, the
membrane 354 may have the same general outer shape as the plates 142 (see
Figures 3-6, 16, and 23). The membranes 354 each include through-holes 470
that correspond to the through-holes 170 (see Figures 6-10, 12-15, and 17-20)
of the plates 401-404 illustrated in Figures 17-20, respectively. Thus,
referring
to Figure 17, the through-holes 470 (see Figure 22) each include
through-holes 471 and 474-476 (see Figure 22) that correspond to the
through-holes 171 and 174-176, respectively. The through-holes 470 are
configured to allow the water 116 (see Figures 1-3), the hydrogen gas 120
(see Figure 2), and the oxygen gas 121 (see Figure 2) to flow therethrough.
Each of the membranes 354 is configured to be sandwiched between a pair of
the seals 352 (see Figures 21 and 23) and to permit flow between the pair of
seals only through the through-holes 470. By way of a non-limiting example,
the membranes 354 (see Figure 22) may each be constructed from vinyl or a
similar material configured to block oxygen and hydrogen from flowing through
the material.
Figure 21 illustrates the seal 352 in a first orientation with its first
and second sealed regions 420 and 422 positioned in the upper right hand and
lower left hand corners, respectively. In this orientation, the front side 231
faces toward the first end cap 146 (see Figures 3-4B, 16, 23, and 24). The
seal 352 may be positioned in a second orientation in which the front side 231
26
CA 03111016 2021-02-26
WO 2020/044207 PCT/IB2019/057170
faces toward the second end cap 148 (see Figures 3-4B, 16, 23, and 24). In
the second orientation, the first and second sealed regions 420 and 422 are
positioned in the upper left hand and lower right hand corners, respectively.
Table A below lists which of the through-holes 170 (see Figures 6-10, 12-15,
and 17-20) of each of the plates 401-404 (see Figures 17-20, respectively) is
positioned inside each of the first and second sealed regions 420 and 422 when
the seal 352 is positioned alongside the plate in the first and second
orientations. For example, when the seal 352 is positioned alongside the
positive plate 401 (see Figure 17) in the first orientation, the through-holes
176
and 174 are positioned inside the first and second sealed regions 420 and 422,
respectively. On the other hand, when the seal 352 is positioned alongside the
positive plate 401 (see Figure 17) in the second orientation, the
through-holes 175 and 171 are positioned inside the first and second sealed
regions 420 and 422, respectively.

Table A
Table A above also lists which of the through-holes 470 (see
Figure 22) of the membrane 354 (see Figure 22) is positioned inside each of
the first and second sealed regions 420 and 422 when the seal 352 is
positioned alongside the membrane 354 in the first and second orientations.
For example, when the seal 352 is positioned alongside the membrane 354
(see Figure 22) in the first orientation, the through-holes 476 and 474 are
positioned inside the first and second sealed regions 420 and 422,
respectively.
On the other hand, when the seal 352 is positioned alongside the
membrane 354 (see Figure 22) in the second orientation, the through-holes 475
and 471 are positioned inside the first and second sealed regions 420 and 422,
respectively.
Figure 23 illustrates an exemplary slice 430 through the cell 350,
which is also illustrated in Figures 16 and 24. Referring to Figure 23, the
slice 430 includes the first end cap 146, the second end cap 148, the
plates 142, the seals 352, and the membranes 354 (see Figure 22). In this
embodiment, the plates 142 include positive plates 401A and 401B, the
negative plate 402, first neutral plates 403A-403D, second neutral
plates 404A-404C. The positive plates 401A and 401B are each like the
positive plate 401 (see Figure 17). The first neutral plates 403A-403D are
each
like the first neutral plate 403 (see Figure 19). The second neutral
plates 404A-404C are each like the second neutral plate 404 (see Figure 20).
The seals 352 include seals 352A-352Q and the membranes 354 (see
Figure 22) include membranes 354A-354F. In the embodiment illustrated, the
first end cap 146, the second end cap 148, the plates 142, the seals 352, and
the membranes 354 (see Figure 22) are arranged in the following order:
1. the first end cap 146;
2. the seal 352A (in the first orientation);
3. the positive plate 401A;
4. the seal 352B (in the first orientation);
5. the second neutral plate 404A;
6. the seal 352C (in the second orientation);
28

11. the membrane 354B;

18. the seal 3521 (in the second orientation);
19. the negative plate 402;
20. the seal 352J (in the first orientation);
21. the membrane 354D;
22. the seal 352K (in the second orientation);
23. the first neutral plate 403C;
24. the seal 352L (in the first orientation);
25. the membrane 354E;

31. the first neutral plate 403D;
32. the seal 352P (in the first orientation);
33. the positive plate 401B;
34. the seal 352Q (in the first orientation); and
35. the second end cap 148
As shown in Figure 24, the seals 352A-352Q define a first gas
chamber 432 (shown using hash marks) and a second gas chamber 434 in the
cell 350. The first and second gas chambers 432 and 434 are isolated from
one another. The first gas chamber 432 (shown using hash marks) may
29
CA 03111016 2021-02-26
WO 2020/044207 PCT/IB2019/057170
temporarily house the oxygen gas 121 (see Figure 2) and conduct it to the
oxygen outlet 362. The second gas chamber 434 may temporarily house the
hydrogen gas 120 (see Figure 2) and conduct it to the hydrogen outlet 244. As
shown in Figure 23, one side of each of the negative plate 402, the first
neutral
plates 403A-403D, the second neutral plates 404A-404C, and the
membranes 354A-354F is positioned in the first gas chamber 432 (see
Figure 24) and the other side of each of these structures is positioned in the
second gas chamber 434 (see Figure 24).
As explained above and shown in Figure 24, the
seals 352A-352Q cause the water 116 (see Figures 1-3) and the oxygen
gas 121 (see Figure 2) to zigzag through the first gas chamber 432 and the
water 116 and the hydrogen gas 120 (see Figure 2) to zig-zag through the
second gas chamber 434. Thus, fewer ones of the through-holes 170 (see
Figures 6-10, 12-15, and 17-20) are needed to create the desired flows. As
mentioned above, the cell 350 may include more than one water inlet like the
water inlet 240 (see Figures 4A and 4B). In such embodiments, at least one of
the water inlets may open into the first gas chamber 432 and at least one of
the
water inlets may open into the second gas chamber 434.
Referring to Figure 21, the seals 352 may be constructed from
any material suitable for constructing the seals 144 (see Figures 4A, 5, and
11).
In alternate embodiments, the seals 144 may be used with the plates 401-404.
In such embodiments, additional seals (e.g., 0-rings) may be used to block or
isolate at least two of the through-holes 170 of the plates 401-404 as
described
above.
POWER CONTROLLER
Figure 25 illustrates an exemplary implementation of the power
controller 108 connected to the hydrogen generator 106 by the electrical
conductors 110. As mentioned above, the power controller 108 may be
connected to the power source 109 (see Figure 1), which may be implemented
as an AC source (e.g., a conventional wall socket). Thus, the power
controller 108 has positive and negative contacts 502 and 504 configured to be
connected to the power source 109 (see Figure 1). By way of a non-limiting
CA 03111016 2021-02-26
WO 2020/044207 PCT/IB2019/057170
example, the positive and negative contacts 502 and 504 may be components
of a conventional plug configured to plug into a conventional (110 V) AC wall
outlet. The AC is conducted to a rectifier 510 that converts the AC to DC.
Conductors 512 and 514 conduct the DC to the positive and negative terminals
T+ and T-, respectively.
In the embodiment illustrated, the negative contact 504 is
connected to the rectifier 510 by a conductor 516. The positive contact 502 is
connected by a conductor 518 to a solid-state relay 520. The solid-state
relay 520 is connected to the rectifier 510 by a conductor 522. The solid-
state
relay 520 includes a potentiometer 530 that is used to determine the voltage
of
the AC input into the rectifier 510. The potentiometer 530 is connected to an
interface 532 that may be operated manually (e.g., a dial) or by a computing
device (not shown). The interface 532 controls the potentiometer 530 and
determines the voltage of the AC input into the rectifier 510. The voltage of
the
DC output by the rectifier 510 depends upon the voltage of the AC input into
the
rectifier 510. Thus, by controlling the voltage of the AC input into the
rectifier 510, the potentiometer 530 determines the voltage of the DC output
by
the rectifier 510.
The voltage of the DC output by the rectifier 510 determines at
least in part the amount of hydrogen gas output by the hydrogen generator 106.
HYDROGEN CONSUMING PROCESS AND/OR DEVICE
Referring to Figure 1, the hydrogen consuming process and/or
device 134 may be any process or device configured to use or consume the
hydrogen gas 120 (see Figure 2). Optionally, the hydrogen consuming process
and/or device 134 may use or consume the oxygen gas 121 (see Figure 2) with
the hydrogen gas 120 (see Figure 2).
The hydrogen consuming process and/or device 134 may be
implemented as a hydrogenation process. By way of another non-limiting
example, the hydrogen consuming process and/or device 134 may be any
device configured to produce an explosion. For example, the hydrogen
consuming process and/or device 134 may be implemented as an internal
combustion engine (e.g., a diesel engine or a gasoline engine). Such an
31
CA 03111016 2021-02-26
WO 2020/044207
PCT/IB2019/057170
internal combustion engine may be incorporated into a vehicle (e.g., a car, a
truck, a motorcycle, a tractor, a bus, a semi-trailer truck, a boat, an
airplane, a
train, etc.). By way of yet another non-limiting example, the hydrogen
consuming process and/or device 134 may be any device configured to
produce a flame used to produce heat and/or light. For example, the hydrogen
consuming process and/or device 134 may be implemented as an oven, an
industrial oven (e.g., configured to melt steel, glass, aluminum, etc.), an
electric

The foregoing described embodiments depict different
components contained within, or connected with, different other components. It
is to be understood that such depicted architectures are merely exemplary, and
that in fact many other architectures can be implemented which achieve the
same functionality. In a conceptual sense, any arrangement of components to
achieve the same functionality is effectively "associated" such that the
desired
functionality is achieved. Hence, any two components herein combined to
achieve a particular functionality can be seen as "associated with" each other
such that the desired functionality is achieved, irrespective of architectures
or
intermedial components. Likewise, any two components so associated can
also be viewed as being "operably connected," or "operably coupled," to each
other to achieve the desired functionality.
While particular embodiments of the present invention have been
shown and described, it will be obvious to those skilled in the art that,
based
upon the teachings herein, changes and modifications may be made without
departing from this invention and its broader aspects and, therefore, the
.. appended claims are to encompass within their scope all such changes and
modifications as are within the true spirit and scope of this invention.
Furthermore, it is to be understood that the invention is solely defined by
the
appended claims. It will be understood by those within the art that, in
general,
terms used herein, and especially in the appended claims (e.g., bodies of the
appended claims) are generally intended as "open" terms (e.g., the term
"including" should be interpreted as "including but not limited to," the term
"having" should be interpreted as "having at least," the term "includes"
should
42
CA 03111016 2021-02-26
WO 2020/044207
PCT/IB2019/057170
be interpreted as "includes but is not limited to," etc.). It will be further
understood by those within the art that if a specific number of an introduced
claim recitation is intended, such an intent will be explicitly recited in the
claim,
and in the absence of such recitation no such intent is present. For example,
as an aid to understanding, the following appended claims may contain usage
of the introductory phrases at least one" and one or more" to introduce claim
recitations. However, the use of such phrases should not be construed to imply
that the introduction of a claim recitation by the indefinite articles "a" or
"an"
limits any particular claim containing such introduced claim recitation to
inventions containing only one such recitation, even when the same claim
includes the introductory phrases one or more" or at least one" and indefinite
articles such as "a" or "an" (e.g., "a" and/or "an" should typically be
interpreted
to mean at least one" or one or more"); the same holds true for the use of
definite articles used to introduce claim recitations. In addition, even if a
specific number of an introduced claim recitation is explicitly recited, those
skilled in the art will recognize that such recitation should typically be
interpreted to mean at least the recited number (e.g., the bare recitation of
two
recitations," without other modifiers, typically means at least two
recitations, or
two or more recitations).
Conjunctive language, such as phrases of the form at least one
of A, B, and C," or at least one of A, B and C," (i.e., the same phrase with
or
without the Oxford comma) unless specifically stated otherwise or otherwise
clearly contradicted by context, is otherwise understood with the context as
used in general to present that an item, term, etc., may be either A or B or
C,
any nonempty subset of the set of A and B and C, or any set not contradicted
by context or otherwise excluded that contains at least one A, at least one B,
or
at least one C. For instance, in the illustrative example of a set having
three
members, the conjunctive phrases at least one of A, B, and C" and at least
one of A, B and C" refer to any of the following sets: {A}, {B}, {C}, {A, B},
{A, C},
{B, C}, {A, B, C}, and, if not contradicted explicitly or by context, any set
having
{A}, {B}, and/or {C} as a subset (e.g., sets with multiple "A"). Thus, such
conjunctive language is not generally intended to imply that certain
embodiments require at least one of A, at least one of B, and at least one of
C
43
CA 03111016 2021-02-26
WO 2020/044207 PCT/IB2019/057170
each to be present. Similarly, phrases such as at least one of A, B, or C" and
at least one of A, B or C" refer to the same as at least one of A, B, and C"
and
at least one of A, B and C" refer to any of the following sets: {A}, {B}, {C},
{A,
B}, {A, C}, {B, C}, {A, B, C}, unless differing meaning is explicitly stated
or clear
from context.
Accordingly, the invention is not limited except as by the
appended claims.
