    摘要： The invention is a hydrogen passivation shut down system for a fuel cell power plant (10, 200). During shut down of the plant (10, 200), hydrogen fuel is permitted to transfer between an anode flow path (24, 24′) and a cathode flow path (38, 38′). A passive hydrogen bleed line (202) permits passage of a smallest amount of hydrogen into the fuel cell (12′) necessary to maintain the fuel cell (12′) in a passive state. A diffusion media (204) may be secured in fluid communication with the bleed line (202) to maintain a constant, slow rate of diffusion of the hydrogen into the fuel cell (12′) despite varying pressure differentials between the shutdown fuel cell (12′) and ambient atmosphere adjacent the cell (12′).

    摘要： A fuel cell is disclosed that includes an electrode assembly arranged between a cathode and an anode. The anode and cathode have lateral surfaces adjoining lateral surface of the electrode assembly and respectively include fuel and oxidant flow fields. Interfacial seals are not arranged between the lateral surfaces. Instead, a sealant is applied to the anode, the cathode and the electrode assembly to fluidly separate the fuel and oxidant flow fields. In one example, the adjoining lateral surfaces are in abutting engagement with one another. The sealant is applied in a liquid, uncured state to perimeter surfaces of the electrode assembly, the anode and the cathode that surround the lateral surfaces.

    摘要： A unitized electrode assembly (9) for use in the fuel cell comprises a first GDL (23), a PEM (28), and a second GDL (12), with electrode catalyst (27, 30) disposed between said PEM and each of said GDLs, said layers (23, 27, 30, 12) being impregnated with a thermoplastic polymer a sufficient distance from each edge of the UEA so as to form a fluid seal (13). The UEA is formed by a process which comprises making a sandwich of some or all of said layers (23, 27, 28, 30 and 33), with thermoplastic polymer film (22, 25, 32, 35) extending inwardly from the edges of said sandwich a sufficient distance to form the seal, said thermoplastic polymer film being disposed between each electrode and the adjacent GDL and/or between each GDL and release film (21, 36) on the top and bottom of the sandwich. The sandwich, compressed by force between a holding fixture (19) and an anvil (40), is heated by ultrasonic vibration so as to cause said thermoplastic polymer to melt and impregnate the layers (23, 27, 30, 12) of the UEA with the film (22 and/or 25; 32 and/or 35).

    摘要： Fuel cells (38) have passageways (83, 84) that provide water through one or both reactant gas flow field plates (75, 81) of each fuel cell, whereby the fuel cell is cooled evaporatively. The water passageways may be vented by a porous plug (not shown), or by a microvacuum pump (89). A condenser (59) may have a reservoir (64); the condenser (59) may be a vehicle radiator. A highly water permeable wicking layer (90) is disposed adjacent to one or both water passageways (83, 84) which exist between individual fuel cells (38). The passageways may be flow-through passageways (83) (FIG. 5) or they may be interdigitated passageways (83a, 83b) (FIG. 6) in order to increase the flow of water-purging air through the wicking layer (90) utilized to clear the stack of water during shutdown in cold environments. The inlet interdigitated channels (83c, 83d) may be only partially blocked at their outlet ends such as by a protrusion (104) or a hole (106) in order to ensure that any gas entering the inlet coolant passageways (83c, 83d) will not accumulate at the outlet end (101) of the inlet coolant passageways.
