The separators have ribs on surfaces facing the gas diffusion layers, the ribs forming channels which are gas flow paths. A thickness t (µm) of each of the gas diffusion layers and an area occupation ratio S C (-) of the channels on the surface facing the gas diffusion layer satisfy the relationship represented by the following formula (1): 0.9 > S C ¥ 55 ¢ t - 103 2 / 1000000 + 0.3",
