PROBLEM TO BE SOLVED: To provide a fuel cell system capable of suppressing decrease in the capacity, by suppressing elution and reprecipitation of a catalyst.SOLUTION: A fuel cell system includes a first on-off valve 126 for opening and closing an anode exhaust part 135B, a second on-off valve 127 for opening and closing a cathode supply part 136A, and a third on-off valve 128 for opening and closing a cathode exhaust part 136B. When the fuel cell system 1 is stopped, liquid fuel supply by fuel supply means 113 is stopped, supply of oxidizer by oxidizer supply means 117 is stopped, and the first on-off valve 126, second on-off valve 127 and third on-off valve 128 are closed.SELECTED DRAWING: Figure 1 |
