Abstract
A gasket for fuel cells includes a gasket body composed of a metal or resin sheet and having openings, and a sealing section composed of a liquid rubber vulcanizate. The sealing section is bonded to the gasket body at low pressure. The inner face of each of the openings is covered with the sealing section. The gasket precludes generation of contaminants, such as ions, by the reaction of working fluids with the material constituting the gasket body, allowing high generating efficiency of the fuel cell.
