Abstract: A multi-layer seal system for a manifold (10) of a proton exchange membrane fuel cell includes a silicone rubber filler layer (22) between endplates (9) to compensate for the uneven edges of cell elements, an elastomer gasket (15) disposed within a groove (24) in the contact surfaces of a manifold (10), and a rigid dielectric strip (40) coplanar with the contact surfaces (17) of the endplates (9) interposed between the silicone rubber filler layer (22) and the gasket (15). The rigid dielectric strip (40) may be either angled (40a) for a corner seal, or flat (40b).

Abstract: 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).

Abstract: 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.

Abstract: A silicon rubber gasket (35) is adhered to an anode substrate (14) by sealant material, such as a thermoplastic polymer, a thermoset polymer or an elastomeric polymer, which is impregnated (31) to provide an edge seal to the anode substrate. In one embodiment, a silicon rubber gasket (36) is adhered to the cathode substrate (26) by the sealant material which is impregnated (32) to provide a gas edge seal to the cathode substrate. Each fuel cell is completed during the formation of a fuel cell stack by compressing the fuel flow field plates and oxidant flow field plates to the unitized electrode assembly with gaskets. In a second embodiment, the oxidant flow field plate (27) is adhered to the cathode substrate by the sealant material which is impregnated into the cathode substrate to provide a gas edge seal, and the fuel flow field plate (18) is adhered to the oxidant flow field plate (27) by means of the sealant material (53). The entire fuel cell with gasket (9a) is formed in a single hot lamination step (45b).
