PROBLEM TO BE SOLVED: To maintain a performance of a cell of a fuel cell even if it is in a state of operation of starting, stopping, or the like. SOLUTION: In a fuel cell system 1 which generates electricity by supplying air containing hydrogen and oxygen to a cell 106 of the fuel battery, the fuel cell 6 is constituted with a cell stack 103 constituted by laminating of an electrode base material B which consists of an ion exchange film 107, a positive catalyst electrode 108, and a negative catalyst electrode 109, and a water storage part A which absorbs the water in the electrode base material B during excess water of the electrode base material B, and supplies water to the electrode base material B during water shortage of the electrode base material B. While arranging the water storage part A approaching to the electrode base material B, water is supplied to the water storage part A continuously from outside of the cell stack 103, immediately after a power generation stop of the fuel cell 6. The water is kept in the water storage part A, and it is constituted so that the water of the water storage part A may be supplied to the electrode base material B at the start-up of the fuel cell 6. |
