FUEL CELL |
摘要 |
Provided is a fuel cell including: a membrane electrode assembly; a pair of gas diffusion layers holding the membrane electrode assembly therebetween; and a pair of separators holding the membrane electrode assembly and the pair of gas diffusion layer therebetween. 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 |
