摘要： A gasket assembly suitable for use in a fuel cell includes a membrane electrode assembly; a separator comprising a manifold structure having a plurality of apertures; and a gasket disposed between the separator and the membrane electrode assembly. The gasket is positioned and configured to prevent the leakage of fluid from the manifold into the membrane electrode assembly and resultant loss in fuel cell performance. A contamination prevention groove is formed on one side of the gasket to form a channel along which any leaking fluid, e.g. antifeeze, can flow.
