PROBLEM TO BE SOLVED: To provide a fuel cell system capable of smoothly providing a sufficient power generation amount in restarting of a fuel cell.SOLUTION: In a fuel cell system 2, a humidifier 51 is interposed halfway in a humidified air supply line 56, a three-way valve 52 is interposed in a connection part among an upstream air supply line 55, the humidified air supply line 56, and a bypass line 58. In restarting of a fuel cell 3, the three-way valve 52 opens a supply direction-upstream end of the bypass line 58 and closes a supply direction-upstream end of the humidified air supply line 56. Then a cathode electrode 17 is supplied with non-humidified air having passed through the bypass line 58. Subsequently, the three-way valve 52 closes the supply direction-upstream end of the bypass line 58 and opens the supply direction-upstream end of the humidified air supply line 56.Then The cathode electrode 17 is supplied with humidified air having passed through the humidified air supply line 56.SELECTED DRAWING: Figure 1 |
