Abstract
A separator for a fuel cell, to be disposed opposing to a membrane electrode assembly, is provided. The separator includes a separator central area portion opposing to a center area of the membrane electrode assembly that concerns generating power, an outer edge portion located in an outer edge of the separator central area portion, a rubber molded body made of rubber, the rubber molded body being formed in the outer edge portion by die-casting a die-casting rubber material using die, and an adhesive layer formed in the outer edge portion, for adhering the rubber molded body to the outer edge portion. The adhesive layer is formed over an adhesive layer area that includes and is larger than an area where the rubber molded body is die-casted in the outer edge portion. Thus, a disadvantage due to burrs which are generated when die-casting the rubber molded body can be reduced.
