Abstract
A quasi-passive regenerative fuel cell system in accordance with the invention utilizes hydrogen that is stored in a metal hydride form. Advantageously, this embodiment reduces the system's operating pressures from roughly 21 MPa (3,000 psia) to roughly 2.1 MPa (300 psia), when fully charged, and eliminates the need for gaseous oxygen storage altogether. All oxygen consumed by the fuel cell system can be extracted directly from the surrounding air. All oxygen produced by the electrolyzer is, in turn, vented back into the atmosphere.
