    摘要： A fuel cell power plant (10) having a fuel concentration sensor cell (54) is disclosed for detecting a concentration of fuel in a fuel cell (12) of the plant (10). A portion of a fuel exhaust stream is directed to flow through the sensor cell (54) adjacent to a membrane electrode assembly (60) of the sensor cell (54). A power circuit (62) may or may not deliver an electrical current to the cell (12), while changes in voltage across the cell (12) that are proportional to changes in hydrogen concentrations within the fuel exhaust stream are detected by a detector (68) which communicates the changes to a controller (108) for controlling a rate of fuel supply to the fuel cell (12). A porous sensor water transport plate (74) cools, humidifies delivers and removes liquid from the sensor cell (12).

    摘要： A PEM fuel cell oxidant flow field plate (12) having a substantial portion (77A) of the flow field formed of interdigitated reactant flow channels (86, 87) includes a humidification zone coextensive with an electrolyte dry-out barrier (38). Within the humidification zone, the reactant flow channels are flow-through channels (89), which permits the inlet reactant flow to be sufficiently slow to permit adequate humidification of the inlet reactant gas from adjacent water, such as coolant water flow channels and/or the anode, to avoid electrolyte dry-out.

    摘要： A flow battery includes at least one electrochemical cell that has a first electrode, a second electrode spaced apart from the first electrode and a separator arranged between the first electrode and the second electrode. A first storage portion and a second storage portion are respectively fluidly connected with the at least one electrochemical cell. A first liquid electrolyte and a second liquid electrolyte are located in the respective first storage portion and second storage portion. The first electrode has an area over which it is catalytically active with regard to the first liquid electrolyte and the second electrode has an area over which it is catalytically active with regard to the second liquid electrolyte such that the area of the first electrode is greater than the area of the second electrode.

    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.
