ABSTRACT:
An apparatus for and method of storing hydrogen gas within an enclosed metal hydride container that is isolated from an apparatus which uses hydrogen gas, including a constricted opening having a valve to selectively open or close the hydrogen gas communication between the hydrogen storage container and the apparatus using the hydrogen. Also included within the hydrogen gas communication between the storage and use is a filter for filtering out oxygen and water vapor molecules from the hydrogen stream passing from the apparatus using the hydrogen to the hydrogen storage metal hydride. The filter means comprises a thin metal disc or a hydrogen gas permeable elastomeric thin film coating, such as a polyethylene resin or silicone oil, either in the hydrogen stream path or as a coating on each of the hydrogen absorbing metal hydride particles which are disposed within the hydrogen storage chamber. The enclosed metal hydride container may be disposed either within the apparatus using the hydrogen gas or externally thereof.
