An object of the present invention is to provide a fuel cell system capable of raising the temperature of a discharge valve and restraining the discharge valve from freezing by a simple structure. The fuel cell system has a circulation system for circulating hydrogen off gas, which is discharged from a fuel cell, to the fuel cell, an exhaust/drain valve for discharging a fluid passing through the circulation system to the outside, and a refrigerant flow path through which a refrigerant, which is circulated to the fuel cell, flows. The exhaust/drain valve has a valve body provided with a flow path which interconnects the interior of the circulation system and the outside. A part of the refrigerant flow path is provided by penetrating the valve body so as to be independent of the flow path. |
