Zusammenfassung:A gas flow passage-forming member is disposed between a membrane electrode and gas diffusion layer assembly and a separator of a fuel cell, and the gas flow passage-forming member is configured to form a gas flow passage. The gas flow passage-forming member has a corrugated shape such that groove portions and ridge portions are provided on each of a front side and a back side of the gas flow passage-forming member. The groove portions each serve as the gas flow passage. The gas flow passage-forming member has communication holes providing communication between the front side and the back side, and the communication holes are provided in a region downstream of an upstream region in a gas flow direction. The upstream region is a non-communication region with no communication hole.
