摘要： A fuel cell stack (31) includes a plurality of fuel cells (9) each having an electrolyte such as a PEM (10), anode and cathode catalyst layers (13, 14), anode and cathode gas diffusion layers (16, 17), and water transport plates (21, 28) adjacent the gas diffusion layers. The cathode diffusion layer of cells near the cathode end (36) of the stack have a high water permeability, such as greater than 3x10 -4 g/(Pa s m) at about 80°C and about 1 atmosphere, whereas the cathode gas diffusion layer in cells near the anode end (35) have water vapor permeance greater than 3x10 -4 g/(Pa s m) at about 80°C and about 1 atmosphere. In one embodiment, the anode gas diffusion layer of cells near the anode end (35) of the stack have a higher liquid water permeability than the anode gas diffusion layer in cells near the cathode end; a second embodiment reverses that relationship.

摘要： A fuel cell includes an electrode assembly having an electrolyte between a cathode catalyst and an anode catalyst, and a flow field plate having a channel for delivering a reactant gas to the electrode assembly. The flow field plate includes a channel having a channel inlet. A porous diffusion layer is located between the electrode assembly and the flow field plate. The porous diffusion layer includes a first region near the channel inlet and a second region downstream from the first region relative to the channel inlet. The first region includes a filler material that partially blocks pores of the first region such that the first region has a first porosity and the second region has a second porosity that is greater than the first porosity.

摘要： A fuel cell (10) includes a cathode catalyst (26) for receiving a first reactant and an anode catalyst (24) for receiving an expected amount of a second reactant. The cathode catalyst (26) and the anode catalyst (24) respectively catalyze the first reactant and the second reactant to produce an electrochemical reaction that generates a flow of electrons between the cathode catalyst (26) and the anode catalyst (24) The amount of the first reactant consumed in the electrochemical reaction corresponds to a threshold amount of the second reactant needed to generate a forward flow of the electrons from the anode catalyst (24) to the cathode catalyst (26). A portion (42) of a fuel cell flow field includes a feature (54, 60, 80, W 1 , D 1 ) that restricts consumption of the first reactant.

摘要： An inlet fuel distributor (10-10d) has a permeable baffle (39, 54,54a, 60) between a fuel supply pipe (11, 83) and a fuel inlet manifold (12, 53, 53a, 63) causing fuel to be uniformly distributed along the length of the fuel inlet manifold. A surface (53, 68) may cause impinging fuel to turn and flow substantially omnidirectionally improving its uniformity. Recycle fuel may be provided (25, 71) into the flow downstream of the fuel inlet distributor. During startup, fuel or inert gas within the inlet fuel distributor and the fuel inlet manifold may be vented through a valve (57, 86) in response to a controller (58, 79) so as to present a uniform fuel front to the inlets of the fuel flow fields (58).

摘要： A PEM fuel cell assembly includes cooler plates (10) with internal coolant manifolds (25) isolated from the cell stack assembly by an isolation gap (28) to minimize the risk of contamination of the cells by antifreeze. The internal coolant manifolds are formed by seal assemblies (24), each disposed between inlet or outlet openings (14, 15) in projections (16) of each cooler plate extending outwardly from the fuel cell planform (20) to provide a gap (28), which may be used as an air turn manifold. Flanges (40) with through holes (41) may receive tie rods to assist assembly of a fuel cell stack with the cooler plate.

摘要： A plurality of cooler plates (9) are disposed between fuel cells (8) in a stack (7) and have protrusions (12, 13) which include coolant inlet and outlet channels (15). The protrusions are surrounded by an elastomeric sealant material (35, 36) which forms a seal with the manifold structures (27, 28) to form coolant inlet and outlet manifolds (17, 20). The sealant material prevents coolant from entering fuel cells along the edges thereof, thereby preventing the fuel cells from being poisoned by the coolant. The coolant inlet and outlet manifold structures (27, 28) also define reactant gas manifolds (18, 21).

摘要： A fuel cell power plant (19) has a stack of fuel cells (20) cooled by a mixture of water with a non-volatile, miscible fluid that sufficiently depresses the freezing point, such as polyethylene glycol (PEG). The water and fluid are mixed in a reservoir (21), a small pump (22, 60) flows the mixture through coolant channels (28) in or adjacent water transport plates (29); heat of the catalytic reaction warms the water transport plates causing water to evaporate therefrom thereby cooling the stack. The PEG is non-volatile at stack operating temperature and does not evaporate; concentrated PEG is returned (33) to the reservoir (21). Water in the process air flow channels (41), including evaporated process water, is recovered in a condensation-rate-controlled (53, 54)) condenser (46) in communication (48) with the reservoir (21) for remixture with the concentrated PEG solution. Hydrophobic gas diffusion layers (72) shield the proton exchange membrane (70) from the PEG.
