<P>PROBLEM TO BE SOLVED: To accurately specify the factor of a negative voltage when a voltage of a fuel cell is negative. <P>SOLUTION: A fuel cell system comprises: a fuel cell; a voltage measuring unit for measuring a voltage of the fuel cell; a current adjusting unit for adjusting a current flowing through the fuel cell; an I-V characteristic information acquiring unit which controls the current adjusting unit to change the current and acquires I-V characteristic information indicating a correspondence relationship between a current value and a voltage value measured by the voltage measuring unit; and a negative voltage factor specifying unit which, when a voltage of the fuel cell is negative, specifies the factor causing the voltage of the fuel cell to be negative, on the basis of acquired I-V characteristic information. <P>COPYRIGHT: (C)2012,JPO&INPIT |
