A component for constituting a fuel cell having a gasket molded integrally with an MEA in which molding of the gasket is required once, the MEA requires no through hole and requires a small fastening force when the MEA is compressed. The component comprises the MEA arranged between a pair of separators and compressed when a cell is assembled; a rubber impregnated portion formed by impregnating the outer peripheral portion of the MEA with a gasket molding material, i.e. a part of rubber; a flat gasket portion composed of the rubber molded integrally on the outer circumferential side of the rubber impregnated portion; a lip formed on the flat gasket portion; and a recess as a clearance when the lip is compressed. The portion impregnated with rubber and the flat gasket portion has a thickness (d3) set equal to the thickness (d2) of the MEA when the cell is assembled. |
