Abstract
Systems and methods are provided in which a fuel cell purge cycle recaptures fluid material such as water and hydrogen from an electrode of a fuel cell and can recycle the hydrogen to the anode, leading to improved fuel cell efficiency with minimal parasitic load. Pressure fluctuations of a hydrogen generation system may be integrated with the fuel cell purge cycle to recycle hydrogen to the fuel cell and water to the hydrogen generation system.
