| 摘要 |
The present invention relates to a fuel cell system including: a fuel cell stack; a hydrogen gas supply device for supplying hydrogen gas filled in a hydrogen tank to the fuel cell stack at a reduced pressure; a supply air duct for supplying air to the fuel cell stack; and an exhaust air duct for discharging excess air from the fuel cell stack. The hydrogen gas supply device is disposed in a heat exchange chamber capable of being communicated with the supply air duct and the exhaust air duct. When the temperature of the hydrogen gas supply device becomes a predetermined temperature (T3L) or lower, air discharged from the fuel cell stack is introduced into the heat exchange chamber. When the temperature of the air discharged from the fuel cell stack becomes a predetermined temperature (T2H) or higher, air introduced into the heat exchange chamber and cooled by the hydrogen gas supply device is supplied to the fuel cell stack. |
