Separator for fuel cell, fuel cell, and manufacturing method of separator

A method of manufacturing a separator for a fuel cell, to be disposed opposing to a membrane electrode assembly of the fuel cell, comprising:

• forming an adhesive layer by applying thermosetting adhesive to an outer edge portion located in an outer edge of a separator central area portion opposing to a center area of the membrane electrode assembly that concerns generating power;
• placing the separator, where the adhesive layer is formed, in a die having a cavity for die-casting a rubber molded body made of rubber;
• injecting die-casting rubber material into the cavity to die-cast the rubber molded body;
• curing by heat the adhesive of the adhesive layer to obtain an adhesive effect and hardening the injected die-casting rubber material,
• wherein forming the adhesive layer includes applying the adhesive 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;
• and
• forming a central area portion side rubber molded body made of rubber by die-casting in the outer edge portion on the separator central area portion side from a position of the rubber molded body,
• wherein the central area portion side rubber molded body is die-casted from die-casting rubber material that leaks from between the die and the adhesive layer when die-casting the rubber molded body, at a height lower than a height of the rubber molded body from a surface of the outer edge portion, and is adhered to the outer edge portion by the adhesive layer, and
• wherein the central area portion side rubber molded body is connected with the rubber molded body on a surface of the adhesive layer by a burr formed from the leaked die-casting rubber material.
