Abstract:
1. A fuel cell system comprising: a fuel cell stack; a hydrogen-gas supply device configured to supply hydrogen gas filled in a hydrogen tank into the fuel cell stack along with pressure reduction of the hydrogen gas; an air supply duct configured to supply air into the fuel cell stack; and an air exhaust duct configured to exhaust surplus air from the fuel cell stack, the fuel cell system, wherein the hydrogen-gas supply device is disposed inside a heat exchange chamber capable of communicating with the air supply duct and the air exhaust duct, the air exhausted from the fuel cell stack is introduced into the heat exchange chamber when a temperature of the hydrogen-gas supply device reaches or falls below a predetermined temperature, and air introduced into the heat exchange chamber and cooled down by the hydrogen-gas supply device is supplied into the fuel cell stack when a temperature of the air exhausted from the fuel cell stack reaches or exceeds a predetermined temperature.
