摘要： An electrochemical fuel cell is provided for converting a fuel reactant stream and an oxidant reactant stream to a reaction product stream and electrical energy. The fuel cell includes a membrane electrode assembly interposed between two separator layers. The separator layers are formed of thin electrically conductive sheet material which is substantially impermeable to the fuel and oxidant reactant streams. The membrane electrode assembly comprises first and second electrode layers formed of porous electrically conductive sheet material. The electrode layers have a catalyst associated therewith, and an ion exchange membrane is interposed between the first and second electrode layers. The electrode layers include passages, such as the interstitial spaces within the electrode material or grooves formed in the surface of the electrode material, for flowing a reactant stream between an inlet and outlet within the electrode layer. The incorporation of the reactant flow passages within the electrode material permits the use of thin, lightweight separator layers, thus providing higher power-to-volume and power-to-weight ratios than conventional fuel cells having reactant flow passages engraved, milled or molded in the separator plates.

摘要： 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 dead-ended 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.

The membrane electrode assembly comprises first and second electrode layers (64, 66) formed of porous electrically conductive sheet material. The electrode layers have a catalyst associated therewith, and an ion exchange membrane is interposed between the first and second electrode layers.
