Abstract
An exemplary embodiment of a regenerative electrochemical cell system, comprises: a fuel cell module, an electrolysis module, a heat exchange, and an inverted hydrogen storage device. The fuel cell module can comprise a fuel cell hydrogen inlet in fluid communication a hydrogen storage system, and a fuel cell oxygen inlet in fluid communication with a surrounding atmosphere and in fluid communication with a gaseous portion of an oxygen/water phase separation device. The electrolysis module can comprise an electrolysis water inlet in fluid communication with the water storage device via the fuel cell module, and an electrolysis water outlet in fluid communication with a second water storage device. The inverted hydrogen storage device can comprise a fluid inlet in fluid communication with an electrolysis hydrogen outlet, and a gas outlet in fluid communication with a fuel cell hydrogen inlet.
