PROBLEM TO BE SOLVED: To moderate accumulation of formed water and accumulation of reaction heat or the like by devising a gas passageway structure, maintain the optimum state for power generation over the entire fuel cell face and improve the whole output characteristics. SOLUTION: In the fuel cell composed of unit cells constituted from an electrolyte and a pair of electrodes, of a separator, and of the gas passageway to partition these unit cells, it has such a fuel cell gas passageway structure that a folding-back part is installed on the way from an entrance to an exit of the gas passageway and that the gas passageway of the downstream side from the folding-back part is formed along and opposing to the gas passageway of the upstream side. |
