A fuel cell includes a gas channel-forming member (30) that forms a channel for supplying a reactant gas to a plane of an electrode. A basic structure of the gas channel-forming member (30) is a corrugated plate portion (32) in which ridge portions (32a) and trough portions (32b) continuously alternate with each other. In the gas channel-forming member (30), a plurality of corrugated plate portions (32) are interconnected. Specifically, two adjacent corrugated plate portions (32, 32) are interconnected so that the trough portions (32b) of one of the two connect to the ridge portions (32a) of the other corrugated plate portion (32). The gas channel-forming member (30) is disposed so that the direction of alignment of the connection planes S formed by the interconnection between the trough portions (32b) and the ridge portions (32a) is parallel to the plane of the electrode. This structure improves the diffusion efficiency of the reactant gas in the gas channel.
Pile à combustible comprenant un élément formant un canal à gaz (30) qui forme un canal pour fournir un gaz réactif à un plan d'une électrode. Une structure de base de l'élément formant un canal à gaz (30) consiste en une partie plaque ondulée (32) dans laquelle alternent en continu des parties surélevées (32a) et des parties creuses (32b). Dans l'élément formant un canal à gaz (30), une pluralité de parties plaques ondulées (32) sont interconnectées. Plus particulièrement, deux parties plaques ondulées adjacentes (32, 32) sont interconnectées, de sorte que les parties creuses (32b) de l'une des deux soient reliées aux parties surélevées (32a) de l'autre partie plaque ondulée (32). L'élément formant un canal à gaz (30) est disposé de sorte que la direction d'alignement des plans de liaison S formés par l'interconnexion entre les parties creuses (32b) et les parties surélevées (32a) soit parallèle au plan de l'électrode. Cette structure améliore l'efficacité de diffusion du gaz réactif dans le canal à gaz.
