<P>PROBLEM TO BE SOLVED: To provide a fuel cell system which can determine abnormality of an adequate insulation resistance value in response to a power generation condition of a fuel cell. <P>SOLUTION: The fuel cell system 10 includes an operating voltage detector 47 for detecting an operating voltage value of a fuel cell stack 11, an insulation resistance detector 46 for detecting an insulation resistance value of an entire system, and a control part 45 for controlling overall operation of the entire system. The control part 45 includes an abnormality determination means 48 for acquiring the insulation resistance value of the entire system by corresponding to the operating voltage value of the fuel cell stack 11, and determining abnormality of insulation resistance based on the acquired operating voltage value and insulation resistance value, and a warning lamp operating means 49 for lighting a warning lamp when determined as the abnormality of insulation resistance. <P>COPYRIGHT: (C)2011,JPO&INPIT |
