English Abstract




A method is described of producing a high-level loading of hydrogen or
deuterium in a metal
hydride such as palladium or nickel hydride. A hydride-forming metal is placed
in a
pressurizable container along with a water disassociating material, preferably
as finely
divided particles of water-reacting metal. Water is provided to react with the
water
disassociating material and evolve hydrogen or deuterium gas at an elevated
pressure. The
hydrogen or deuterium then flows to the metal hydride increasing the loading
of the metal
hydride with hydrogen or deuterium to a ratio in excess of 0.85.


Note: Claims are shown in the official language in which they were submitted.



CLAIMS

The embodiments of the invention in which an exclusive property or privilege
is claimed are
defined as follows:


1. A method of loading a hydride-forming metal with hydrogen or deuterium
comprising the
steps of:

a) providing in a pressure-tight closed containment volume a water
disassociating
material and a hydride-forming metal

b) exposing the water disassociating material to water, which is either light
water, heavy
water, or a mixture of both, under conditions whereby the water will be
reduced to
release hydrogen or deuterium gas, and

c) allowing the hydrogen or deuterium gas so formed to diffuse into the
hydride-forming
metal,

thereby providing the metal hydride with an increased loading of hydrogen or
deuterium.

2. A method as in claim 1 wherein the hydride-forming metal is pre-loaded with
hydrogen or
deuterium up to a level in excess of 0.7:1.

3. A container comprising a pressure-tight closed containment volume
containing a mixture
of the oxide of water disassociating and a hydride-forming metal loaded with
hydrogen or
deuterium atoms with a loading ratio in excess of 0.85:1 formed by the process
of claim 1.
4. A container as in claim 3 containing hydrogen or deuterium gas under a
pressure of at
least 10 atmospheres.

5. A container as in claim 3 comprising pressure-tight electrical connections
for supplying
current to components within the containment volume.

6. The method of claim 1 wherein the water when initially exposed to the water

disassociating material is in a frozen condition, followed by the step of
providing heat to
release water vapor for reaction with the water disassociating-material.

7. The method of claim 1 wherein the assembly of the water disassociating
material and
hydride-forming metal in the containment volume is effected by placing such
components in
a container which is placed in turn positioned in a pressurizable containment
vessel with
passages for delivering water to the containment volume and including the
further the steps
of:

11



1. delivering water to the containment volume within the partially-open
container for
reaction with the water disassociating material to produce hydrogen or
deuterium,
2. closing the container to limit the escape of hydrogen or deuterium after
the hydrogen
or deuterium has evolved and diffused into the hydride-forming metal,
3. removing the pressure containment vessel from the assembly containment
vessel, and
4. sealing the pressure containment vessel to prevent the escape of hydrogen
or
deuterium,

thereby providing a portable container of hydride-forming metal loaded with
hydrogen or
deuterium under pressure.

8. The method of any one of claims 1, 2, 6, or 7 wherein the water
disassociating material is
selected from the group consisting of aluminum and zirconium, and the hydride-
forming
metal is selected from the group consisting of nickel and palladium.

9. The container of any one of claims 3, 4 or 5 wherein the oxide of a water
disassociating is
an oxide selected from the group of aluminum oxide and zirconium oxide, and
the hydride
forming metal is selected from the group consisting of nickel and palladium.

10. The container of any one of claims 3, 4 or 5 wherein the oxide of a water
disassociating
is an oxide selected from the group of aluminum oxide and zirconium oxide, and
the hydride
forming metal is selected from the group consisting of nickel and palladium.
