The accuracy of detecting gas leakage in a fuel battery system is improved. The fuel battery system (10) is provided with a fuel battery (20), which generates power by being supplied with a reaction gas, and gas paths (a fuel gas supply path (31) and a fuel gas circulating path (32)) connected to the fuel battery (20). In the gas paths, a plurality of adjoining closed spaces are formed. The fuel battery system is also provided with a detecting means (a control section (50)) which detects gas leakage in one closed space subject to gas leakage detection, in a status where pressure is reduced at least in other closed space adjoining the one closed space in the downstream. |
