A fuel cell assembly has a fuel cell stack ( 1 ) provided with a polymer electrolyte membrane ( 2 ), an air electrode ( 4 ) and a fuel electrode ( 3 ); an air supply device ( 19 ) for supplying air; a fuel gas supply device ( 20 ) for supplying fuel gas, and a humidity regulation module ( 5 ) allowing movement of water from a humid air passage ( 6 ) to a dry air passage ( 7 ). The air electrode ( 4 ) is divided into an upstream air electrode ( 4 a) and a downstream air electrode ( 4 b). The air supplied from the air supply device ( 19 ) is supplied to the upstream air electrode ( 4 a) after passing through the dry air passage ( 7 ). The air discharged from the upstream air electrode ( 4 a) is supplied to the downstream air electrode ( 4 b) after passing through the humid air passage ( 6 ).
