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.
