<p>A sealant system (13a) for a manifold (10) of a proton exchange membrane fuel cell includes low temperature silicone rubber bridges between the end plates (9) to compensate for the uneven edges of various fuel cell component layers (8), and a layer of silicone rubber foam or sponge, or silicone rubber seal (15a), extending across the bridges and along the end plates, around the entire contact perimeter surfaces of the manifold to the fuel cell. A rubber strip (20) may be adhered to the rubber bridges and end plates. The bridges may comprise a first layer (22) of low shrinkage self-leveling RTV liquid rubber with viscosity in the range of 10,000 - 20,000 cps and a second layer (14a) of liquid rubber.</p> |
