摘要： A membrane electrode assembly includes an anode including a hydrogen oxidation catalyst; a cathode; a membrane disposed between the anode and the cathode; and a peroxide decomposition catalyst positioned in at least one position selected from the group consisting of a layer between the anode and the membrane and a layer between the cathode and the membrane wherein the peroxide decomposition catalyst has selectivity when exposed to hydrogen peroxide toward reactions which form benign products from the hydrogen peroxide. The peroxide decomposition catalyst can also be positioned within the membrane. Also disclosed is a power-generating fuel cell system including such a membrane electrode assembly, and a process for operating such a fuel cell system. The assembly components contain ionomer material which can be perfluorinated or non-perfluorinated, high temperature, hydrocarbon, and the like.

摘要： A membrane electrode assembly includes a membrane, an anode catalyst layer and a cathode catalyst layer. The anode catalyst layer is on a first side of the membrane and the cathode catalyst layer is on a second side of the membrane, wherein the second side of the membrane is opposite the first side of the membrane along a first axis. The cathode catalyst layer includes agglomerates formed of a catalyst support supporting catalyst particles, an agglomerate ionomer and an inter-agglomerate ionomer. The agglomerate ionomer surrounds the agglomerates and the inter-agglomerate ionomer is in regions between the agglomerates surrounded by the agglomerate ionomer. The agglomerate ionomer is different than the inter-agglomerate. Methods to produce the catalyst layer are also provided.

摘要： A technique is disclosed of modified shutdown of a fuel cell power plant (14) having a fuel eel! stack assembly (26) contained with and supplying electrical power to a mobile vehicle (12). The -vehicle characteristically proceeds at intervals to a station. (10) containing one or more resources (20, 20A, 20B, 20C, etc) utilized by the fuel cell power plant, for resupply thereof. One such, resource provided at/by the station is electrical energy (20A), aid operation of the fuel cell power plant (14) is controlled to utilize the availability of that electrical energy (20A) to maintain, an active protective Hydrogen On condition for greatly extended intervals, for example many hours to several days or longer, via a Power On mode of operation. The Power On mode maintains at least a low level of hydrogen introduction and circulation sufficient to maintain a predetermined presence, e.g., pressure, of hydrogen at the fuel cell stack assembly (26).

摘要： Fuel cell systems and related methods involving accumulators with multiple regions of differing water fill rates are provided. At least one accumulator region with a relatively more-rapid fill rate than another accumulator region is drained of water at shutdown under freezing conditions to allow at least that region to be free of water and ice. That region is then available to receive water from and supply water to, a fuel cell nominally upon start-up. The region having the relatively more-rapid fill rate may typically be of relatively lesser volume, and may be positioned either relatively below or relatively above the other region(s).

摘要： A fuel cell includes a membrane electrode assembly having an anode side and a cathode side, a first gas diffusion layer adjacent the cathode side of the membrane electrode assembly, and a first flow field plate contacting the first gas diffusion layer. The first flow field plate includes a reactant inlet, a reactant outlet, and a plurality of flow field chambers separated from one another by at least one rib. The reactant inlet is separated from the plurality of flow field chambers by at least one rib and the reactant outlet is separated from the plurality of flow field chambers by at least one rib. The ribs are configured to force a reactant flowing from the reactant inlet to the reactant outlet to enter the first gas diffusion layer at least twice.
