摘要： The fuel cell (100) includes an oxidant flow plate (212), an adjacent cathode substrate layer (216) having a cathode catalyst (222), a matrix (224) for retaining a liquid electrolyte (230), wherein the matrix (224) is secured adjacent and between the cathode catalyst (222) and an anode catalyst (232). A first anode substrate (102) is secured adjacent the anode catalyst (232), and at least a second duplicate anode substrate layer (108) is secured adjacent the first anode substrate layer (102) for providing greater pore volume for storage of the liquid electrolyte (230) and to limit obstruction of the pore volume of the anode substrates (102, 108). The duplicate anode substrate layer (108) may be partially filled with the liquid electrolyte (230) at the beginning of life of the fuel cell (100).

摘要： According to an example embodiment, a method of making a fuel cell component includes permeating at least a portion of a component layer with a polymer. The portion of the component layer is adjacent an edge of the component layer. Some of the polymer is allowed to extend beyond the edge to thereby establish a flap beyond the edge of the component layer. A fuel cell component includes a component layer having a portion adjacent an edge of the layer that is impregnated with a polymer material and a flap of the polymer material extending beyond the edge.

摘要： An illustrative example fuel cell assembly includes a plurality of cells respectively including at least an electrolyte layer, an anode flow plate on one side of the electrolyte layer, and a cathode flow plate on an opposite side of the electrolyte layer. At least one cooler is situated adjacent a first one of the cells. The cooler is closer to that first one of the cells than it is to a second one of the cells. The cathode flow plates respectively include a plurality of flow channels and the anode flow plates respectively include a plurality of flow channels. The anode flow plates respectively include some of the flow channels in a condensation zone of the fuel cell assembly. The flow channels of the anode flow plate in the condensation zone of the first one of the cells have a first flow capacity. The flow channels of the anode flow plate of the second one of the cells that are in the condensation zone have a second flow capacity. The second flow capacity is greater than the first flow capacity.

摘要： According to an example embodiment, a method of making a phosphoric acid fuel cell component includes situating at least one polymer film layer against a permeable component layer. The polymer film layer comprises a polymer that is chemically resistant to phosphoric acid. The polymer film layer is melted. The permeable component layer is impregnated with the melted polymer to thereby establish a region on the component layer that is impermeable to phosphoric acid. The impregnated region also provides a seal against reactant leakage from the component.
