Abstract:
A segmented metal hydride hydrogen gas storage system comprising:a) a hermetically enclosed containment can;b) an apparatus which consumes hydrogen gas in a reversible electrochemical reaction, said apparatus being disposed within the containment can;c) a hydrogen storage chamber having at least one means for fluid communication between said hydrogen storage chamber and said apparatus and being otherwise hermetically sealed from said apparatus, said hydrogen storage chamber containing a metal hydride material, capable of releasably absorbing and discharging gaseous hydrogen and for retaining and storing a concentrated volume of hydrogen;d) a dual one way valve means disposed within each said at least one fluid communication means between said apparatus and said enclosed hydrogen storage chamber, said dual one way valve means permitting reversible communication of a hydrogen gas stream flow between said battery and said chamber in one direction at any particular time, said fluid communication direction depending on the pressure differential across said dual one-way valve being greater than a predetermined threshold pressure.
