Metal hydride fuel cell

[6][7] A notable feature is their ability to chemically bond and store hydrogen within the fuel cell itself.

Metal hydride fuel cells have demonstrated the following characteristics:[8][9][10] Electrode active areas of metal hydride fuel cells have been scaled up from 60 cm2 to 250 cm2, enabling systems to be scaled up to 500 Watts.

[12] To test durability, fuel cell stacks were successfully operated for more than 7000 hours.

[12] Additional developments in both the fuel cell stack and system integration enabled a 1.0 kW system, complete with an inverter and onboard hydrogen storage using metal hydride storage canisters, to be operated and demonstrated in public.

[17] Despite challenges,[18] the military maintains an active interest in fuel cells for a broad range of applications, including unmanned aerial vehicles, autonomous underwater vehicle, light-duty trucks, buses, and wearable technology systems.
