FUEL CELL SYSTEM

摘要

A fuel cell system in which a simple structure enables a temperature increase of a discharge valve and suppression of freezing of the discharge valve. The fuel cell system has a circulation system for circulating and supplying hydrogen off-gas, which is discharged from a fuel cell, to the fuel cell, a gas discharge/water discharge valve for discharging fluid flowing in the circulation system to the outside, and a refrigerant flow path where refrigerant circulated and supplied to the fuel cell flows. The gas discharge/water discharge valve has a valve body provided with a flow path for interconnecting the inside of the circulation system and the outside. A part of the refrigerant flow path is provided in the valve body so as to penetrate through the valve body and be independent of the flow path.
