Abstract
This fuel cell system is equipped with a fuel cell having a reaction gas flow passage, generating power by the reaction gas being supplied to the reaction gas flow passage, having a refrigerant flow passage, and cooled by the refrigerant being supplied to the refrigerant flow passage; a reaction gas supply device for supplying the reaction gas to the reaction gas flow passage; a refrigerant supply device for supplying the refrigerant to the refrigerant flow passage; a refrigerant supply restriction device for restricting a refrigerant supply amount to the refrigerant flow passage; and a controller for controlling the refrigerant supply restriction device, wherein the reaction gas refrigerant supply devices have a drive device in common and are integrally driven, and wherein when warming up the fuel cell, the controller controls the refrigerant supply restriction device and reduces the refrigerant supply amount to the refrigerant flow passage.
