Fuel cell and fuel cell system

Abstract

In a fuel cell 200, comprising: a membrane electrode assembly 204 equipped with an electrolyte membrane 201 and an anode catalyst 202; a supply member 240 for supplying an anode fluid to the membrane electrode assembly 204; and a gas diffusion layer 230 provided between the supply member 240 and the membrane electrode assembly 204, the supply member 240 is provided with an anode fluid flow path 241 for supplying the anode fluid toward the membrane electrode assembly 204, an opening of the anode fluid flow path 241 on a discharge side thereof for the anode fluid is provided in contact with the gas diffusion layer 230, and a region A for storing a gas pushed away by supply of the anode fluid is provided on a side of the gas diffusion layer 230 facing the supply member 240.
