摘要 |
A fuel cell system is provided which can accurately detect an insulation resistance even during a high-potential prevention control. The fuel cell system includes: a fuel cell that generates electric power through an electrochemical reaction between a fuel gas and an oxidant gas; an insulation resistance measurement unit that measures an insulation resistance between the fuel cell and an outer conductor; and a control unit that controls a power generation state of the fuel cell, and the control unit carries out a high-potential prevention control that avoids a voltage of the fuel cell becoming equal to or higher than a predetermined high-potential prevention voltage threshold lower than an open circuit voltage of the fuel cell, and changes the high-potential prevention voltage threshold during an insulation resistance detection performed by the insulation resistance measurement unit. |
