ABSTRACT:
A gasket for a fuel cell, wherein the gasket includes the use of two or more different materials as the gasket. For example, ethylene propylene diene monomer (EPDM) and/or the like, or another more chemically inert gasket material, is located inside or on an inboard position and is the wetted material that is exposed to the fuel cell operating environment. Silicone and/or the like, or another potentially contaminating material with better cold temperature sealability, is located outside or on an outboard position and does not come in contact with the fuel cell internal environment. One method of constructing such a gasket would be two include two parallel bead traces of the gasket materials on a polyimide (e.g., KAPTON®) carrier, or the like.
