Abstract

A solid polymer fuel cell electric power generation system (10) removes a substantial portion of water accumulated at the cathode in the outlet fuel stream (18) of the anode. The system permits the operation of a hydrogen/oxygen fuel cell (1) in a deadended mode where substantially pure oxygen is employed as the oxidant supply (54) or using low oxygen stoichiometry where a dilute oxidant source, such as oxygen-containing air, is employed as the oxidant supply. The supply system thereby eliminates the need for an oxygen recirculation pump in systems operating on substantially pure oxygen, and substantially reduces the parasitic load to pressurize the oxidant stream in systems operating on dilute oxidant streams.
