<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of preventing a voltage of at least one cell in a fuel cell stack from becoming ≤0 V, and of preventing performance deterioration of the fuel cell. <P>SOLUTION: The fuel cell system 1 includes the fuel cell stack 10 and a control unit 20 to detect the voltage of the fuel cell stack 10 and to control an output current of the fuel cell stack 10 according to the detected voltage value. The control unit 20 makes an output electric current value smaller than a normal electric current value output when the detected voltage value is not a first prescribed voltage value or more when the detected voltage value becomes the first prescribed voltage value or more in the case the fuel gas and an oxidizer gas are supplied to the fuel cell stack 10. <P>COPYRIGHT: (C)2007,JPO&INPIT |
