PROBLEM TO BE SOLVED: To improve drainage of water in a headrace channel of a gas flow channel forming body, reduce water in a gas flow channel, improve diffusibility of gas, and enhance battery performance of a fuel cell.SOLUTION: Communication channels 36, 136 through which water passes are mounted between gas flow channels 32, 132 adjacent to headrace channels 33, 133 and the headrace channels 33, 133 of gas flow channel forming bodies 31, 41, and promoting portions 39, 139 which promote connection between waters respectively discharged from discharge side ends of the headrace channels 33, 133 adjacent to each other are mounted on the discharge side ends of the headrace channels 33, 133 adjacent to each other. Therefore, it is possible to improve drainage of water in the headrace channel of the gas flow channel forming body, reduce water in the gas flow channel, improve diffusibility of gas, and enhance battery performance of a fuel cell.
