ABSTRACT:
A fuel cell includes a gas channel-forming member that forms a channel for supplying a reactant gas to a plane of an electrode. A basic structure of the gas channel-forming member is a corrugated plate portion in which ridge portions and trough portions continuously alternate with each other. In the gas channel-forming member, a plurality of corrugated plate portions are interconnected. Specifically, two adjacent corrugated plate portions are interconnected so that the trough portions of one of the two connect to the ridge portions of the other corrugated plate portion. The gas channel-forming member is disposed so that the direction of alignment of the connection planes S formed by the interconnection between the trough portions and the ridge portions is parallel to the plane of the electrode. This structure improves the diffusion efficiency of the reactant gas in the gas channel.
