<P>PROBLEM TO BE SOLVED: To provide a fuel cell system in which maintenance and repairs can be carried out without using excessive man-hours by specifying defective points in a cooling system and factors which have caused the defects. <P>SOLUTION: The fuel cell system is constituted by a fuel cell 10, a cooling system circulating and supplying cooling water to the fuel cell 10, an ohmmeter measuring a resistance value between the front and rear sides in a cooling liquid circulation passage of the components constituting the cooling system, and a management means which manages conductivity in the cooling system based on measured results by the ohmmeter to specify the factors or places of the defects in the cooling system. The cooling system has a radiator 20, a cooling-water pump 30, an ion exchange resin filter 40, as well as the fuel cell 10 and pipes connecting these components, and the ohmmeter measures the resistance value between the front and rear sides of the components such as the radiator 20, the cooling-water pump 30, or pipes having possibility of causing defects. <P>COPYRIGHT: (C)2007,JPO&INPIT |
