A fluid flow field of a separator of a fuel cell stack allows a fluid to flow in a separator surface direction. A rubber seal member provides a seal between the fluid passage and the fluid flow field. The tunnel portion intersects the rubber seal member at an intersection. The tunnel portion allows the fluid flow field and the fluid passage to connect to each other. In the rubber seal member, a first portion protrudes from a flat portion in a stacking direction, and a second portion protrudes from a protruding end surface of a tunnel portion in the stacking direction.

The present invention provides a method for manufacturing rubber parts monolithically combined with the substrate capable of molding, vulcanizing and adhering at a relatively low temperature. The method by the present invention for manufacturing rubber parts monolithically combined with a completed substrate, is a method to form rubber parts at precise positions on a substratecomprising: a placing step to place the substratein a die assembly K for molding rubber parts; a molding step to mold the rubber parts by casting unvulcanized rubber materialinto the die assembly K in which the substrateis placed; a releasing step to take unvulcanized rubber partsmonolithically combined with the substrateout of the die assembly and a vulcanizing step to vulcanize the rubber parts monolithically combined with the substrate.
