Abstract
A fuel cell has a membrane electrode assembly and a supply member for supplying an anode fluid to the membrane electrode assembly. The membrane electrode assembly has an electrolyte membrane and an anode catalyst. The supply member has at least one anode fluid flow path for supplying the anode fluid toward the membrane electrode assembly. A gas diffusion layer is provided between the supply member and the membrane electrode assembly. An opening of the at least one anode fluid flow path on a discharge side thereof for the anode fluid is disposed in contact with a side of the gas diffusion layer facing the supply member. The side of the gas diffusion layer includes a region that stores a gas pushed by the supply of the anode fluid.
