Abstract
This invention relates to 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 hydrogen-gas supply device is disposed inside a heat exchange chamber capable of communicating with the air supply duct and the air exhaust duct.
Claims9
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.
