초록

A thermally energized fuel-cell pressurization system and humidity control system utilizing a compressor-expander, an ejector, and a steam generator is disclosed. The system can be more compact and energy efficient than comparable electrically-based pressurization systems when incorporated into the fuel cell reformation and water management systems as a whole.

청구항

1. A pressurized fuel cell system comprising: a. a fuel cell (98); b. a compressor-expander (70); c. an ejector (1); d. a boiler (94); wherein, pressurized and energetic products of reaction from said fuel cell (98) are conducted through a conduit (86) to the primary fluid inlet conduit (71) of said compressor-expander (70) wherein said products of reaction are de-energized and discharged from the system, said primary fluid imparting energy on a reactant-rich secondary fluid which is introduced to said compressor-expander through secondary fluid i...
