A fuel cell includes a membrane electrode assembly interposed between a cathode-side separator and an anode-side separator. A first gas diffusion layer included in a cathode is designed to have a planar size larger than a planar size of a second gas diffusion layer included in an anode. The anode-side separator has a thin clearance part in a portion that faces an outer peripheral portion of the second gas diffusion layer. |
