PROBLEM TO BE SOLVED: To suppress impairment such as deformation, cracking, and the like, of a protrusion, when the water produced and accumulated in a space formed between the protrusion and a plate is frozen.SOLUTION: A separator for fuel cell includes an opening for forming a manifold in a fuel cell, a protrusion arranged around the opening while having a wavy cross-sectional shape, and sealing around the opening by coming into contact with a member adjacent to the side opposite from the plate in the fuel cell, and deforming elastically, a gas flow path forming section for forming a gas flow path by coming into contact with the plate, and a groove communicating with the space formed between the protrusion and plate in the fuel cell, and located lower than the intersection of the gas flow path and the space when the fuel cell is mounted. |
