摘要： Fuel cell reactant flow field plates (22, 32) are formed by extruding long sections (17, 25) of carbonaceous material, either with straight grooves (18, 28) formed by the extrusion die, or by end milling or arbor milling, and then cut to a proper size, including cuts in which the edges of the plates are at an angle with respect to the grooves. Cooler plates are formed of water-permeable material (39) in which hydrophobic material (40) is impregnated so as to define coolant channels (42, 44) with inlets and outlets (47, 49). A two-layer cooler plate is formed by stamping voids in one layer (51) that define coolant flow channels (52) with inlets (54) and outlets (56) while a second layer (59) is stamped with voids (61, 62) that define coolant inlet and exit headers; juxtaposition of the layers, with or without bonding, form the cooler plate. A cooler plate (65) is made by corrugating thin metal sheet, providing coolant channels (68) for cathodes and coolant channels (74) for anodes when interposed therebetween.

摘要： Rows (50-55, 60-65, 70-73, 80-83, 90-93) of projections (27-28) disposed in reactant gas channels (21) are disposed at intervals along the length of reactant flow fields (20), the rows being more sparse near the inlet end (47) of the flow field and more dense near the outlet end (48) of the flow field or being increasingly more obstructive in shape or size, so that the obstruction to reactant gas flow is approximately proportional to the degree of reactant depletion in the flow. Alternatively, projections (29) may be more shallow near the inlet end of a reactant flow field but larger and therefore more occlusive at the downstream end of the flow field, to provide obstruction to the flow which is approximately proportional to the degree of reactant depletion in the flow. Projections may be in staggered rows (80-87, 90-97) or in random patterns.

摘要： A fuel cell system includes a fuel cell having a cathode and an anode. A water flow field is in communication with the cathode for producing moist air. A cooling system for an evaporatively cooled fuel cell includes a condenser arranged to receive the moist air and produce condensed water. A separator may be arranged to receive the condensed water. A return line fluidly connects the separator and the water flow field. A reservoir has additional water that is in fluid communication with the return line for selectively providing the additional water to the water flow field in an out-of-balance hot fuel cell condition. The reservoir is connected in and to the cooling system in a manner that does not block water flow if the reservoir freezes.

摘要： A fuel cell power plant (19, 19a) has a plurality of fuel cells (70, 70a, 70c) arranged in a stack (20, 20c), each fuel cell having porous, at least partially hydrophilic water transport plates (75, 81) with fuel (74) and oxidant (82) reactant gas channels, there being water channels (78, 85, 78a, 85a, 78c, 85c) exchanging water with the water transport plates. On shut down, water is retained in the water channels and water transport plates by means of either a micro vacuum pump (46), one or two valves (89, 90, 118, 120), a check valve (95, 99), capillary force in the water channels to prevent water from entering the reactant channels which, if frozen, could block flow of reactant gas upon startup.

Further, said step of adjusting comprises adjusting the stack voltage to the lesser of: a) a predetermined voltage above which corrosion of catalyst support material is significant and below which corrosion of catalyst support material is insignificant at the temperature of the stack; and b) a predetermined voltage above which dissolution of catalyst is significant and below which dissolution of the catalyst is insignificant at the temperature of the stack.

摘要： A fuel cell power plant (10) includes an oxidant stream controlled to enter a fuel cell (12) of the plant at a pressure of between about.058 pounds per square inch gas ('psig') and about 4.4 psig and the oxidant stream passes through the fuel cell (12) at an oxidant stoichiometry of between about 120% and about 180%, and preferably between about 150% and 170%. A macro-pore cathode gas diffusion layer (36) is secured between a cathode catalyst (16) and a cathode flow field (28). A porous coolant plate (44) is secured in fluid communication with and adjacent the cathode flow field (28). The gas diffusion layer (36) and coolant plate (44) facilitate removal of product water to eliminate flooding and to permit operation at low oxidant stoichiometry and high water balance temperature, thereby minimizing need for water capture and heat rejection apparatus.
