Abstract: A composite seal having a multilayer elastomeric construction and method for constructing the same is provided. More specifically, the present invention provides a composite seal comprised of a low-durometer elastomer compliant layer coated with, or alternatively encapsulated by, a thin protective layer for securely sealing a bipolar plate and a membrane electrode assembly of a fuel cell. The elastomer compliant layer is preferably a silicone constituent and the thin coat protective layer is preferably a fluoroelastomer or fluoropolymer constituent suitable for bonding to the elastomer compliant layer. The foregoing layers constructing the composite seal are preferably deposited directly onto the aforementioned fuel cell components along a predetermined periphery. The resulting composite seal is thin in construction, resistive to undesired chemical and thermal reactions and provides the necessary compressive compliance without undue stress on the fuel cell assembly.
