To provide a fuel cell capable of restraining occurrence of temperature difference on a cell face while solving the problem of flooding.
On the fuel cell 100 having an MEA 10 and a separator 20, reaction gas flow passages 411 to 416 are formed on a surface 400 of the separator facing the MEA, and porous parts 25 to 27 are formed at least a part of the separator, and cooling gas flow passages 311 to 313 are formed at the opposite side 300 of the reaction gas flow passage at porous part, and cooling water flow passages 321 to 323 are formed at the remaining part of the opposite side 300 of the reaction gas flow passage. It is constructed so that single or a plurality of cooling gas flow passages are interposed between the cooling water flow passages at least at one part of the separator.
