Abstract: A hydride heat engine produces electricity from a heat source, such as a solar heater. A plurality of metal hydride reservoirs are heated by the heating device and a working fluid comprises hydrogen is incrementally move from one metal hydride reservoir to a success metal hydride reservoir. The working fluid is passed, at a high pressure, from the last of the plurality of metal hydride reservoirs to an electro-chemical-expander. The electro-chemical-expander has an anode, a cathode, and an ionomer therebetween. The hydrogen is passed from the anode at high pressure to the cathode at lower pressure and electricity is generated. The solar heater may be a solar water heater and the hot water may heat the metal hydride reservoirs to move the hydrogen. The working fluid may move in a closed loop.

Abstract: A regenerative fuel cell produces hydrogen that is stored in a reservoir on the storage side of a membrane electrode assembly when operating in a hydrogen pumping mode and this stored hydrogen is reacted and moved back through the membrane electrode assembly to form water when operating in a fuel cell mode. A metal hydride forming alloy may be configured in the hydrogen storage reservoir and may be coupled to the membrane electrode assembly. An integral metal hydride electrode having a metal hydride forming alloy may be configured on the storage side of the membrane electrode assembly and may have a catalyst or an ion conductive media incorporated therewith.
