To start a fuel cell system regardless of a pressure of hydrogen when power capacity of a secondary cell system is deficient.
A fuel cell includes a fuel cell stack 1 for generating power by reaction of hydrogen and oxygen contained in the air, an anode line (a) for supplying hydrogen to the fuel cell stack 1, and a cathode line (c) for supplying air. A hydrogen supplying device 15 and a solenoid valve 12 for opening/closing the anode line (a) are connected to the anode line (a). The cathode line c is provided with a fan 13 for feeding air. The anode line (a) is also provided with an anode bypass line (a') for detouring the solenoid valve 12. An open/close valve 22 is provided in a midway of the anode bypass line (a'). While the solenoid valve 12 is closed, if the open/close valve 22 is opened, the hydrogen flowing in the anode bypass line (a') is supplied to the fuel cell stack 1 so that the fuel cell stack 1 generates power and the fuel cell starts, consequently the power can be supplied to a load 8.
