The hydrogen concentration in an anode gas passage of a fuel cell is obtained. When the fuel cell system is started up, one of a first start-up control and a second start-up control is selected based on the obtained hydrogen concentration in the anode gas passage. In the first start-up control, the power generation of the fuel cell is started after purging the anode gas passage. In the second start-up control, the power generation of the fuel cell is started without purging the anode gas passage. |
