Fuel cell

Abstract

A fuel cell which does not discharge fuel gas supplied to an anode (22) thereof to the outside at least during normal power generation having a gas diffusion layer (15) of a conductive porous material stacked on the anode (22) and having fuel gas flow passages therein through which fuel gas is supplied to the anode (22); a sealing part (16) disposed around the gas diffusion layer for preventing leakage of the fuel gas to the outside of a single cell (10); a gas supply part (52) for supplying the fuel gas; and a first fuel gas supply flow passage formed by a gap between at least a part of a periphery of the gas diffusion layer (15) and the sealing part (16) for supplying the fuel gas supplied from the gas supply part (52) to the gas diffusion layer (15).
