ABSTRACT:
A fuel cell gasket employed to seal around an individual cell of a fuel cell assembly. The gaskets include sealing beads that are compressed against separator plates. Adhesive layers located between the gaskets and separator plates hold the gaskets against the separator plates and maintain a desired pre-load on the sealing beads. These structural seals provide good seals along the surfaces of the separator plates, thus reducing or eliminating the need for bolts to maintain the pre-load on the sealing beads of the gaskets.
