Abstract:
1. A fuel cell, comprising: a membrane electrode assembly comprised of an electrolyte membrane and an anode catalyst; a supply member for supplying an anode fluid to the membrane electrode assembly, the supply member having a plurality of anode fluid flow paths penetrating the supply member for supplying the anode fluid so as to be directed toward a surface of the membrane electrode assembly, and the supply member having a plurality of protruding portions through which the respective fluid flow paths are formed; and a gas diffusion layer provided between the supply member and the membrane electrode assembly, an opening of each of the anode fluid flow paths on a discharge side thereof for the anode fluid being disposed in contact with a side of the gas diffusion layer facing the supply member, the protruding portions of the supply member protruding toward the gas diffusion layer with a leading end surface of each of the protruding portions being disposed in contact with the gas diffusion layer, and the supply member including a region that confronts the side of the gas diffusion layer and that stores a gas pushed by the supply of the anode fluid, the region comprising at least one space formed in a portion of the supply member other than portions of the supply member in which the anode fluid flow paths are formed.
