Abstract
In a fuel cell system, mixture fuel having a certain fuel concentration is supplied to an anode, electric power is output from between the anode and the cathode due to electrochemical reaction when the cathode makes contact with air, and unreacted fuel containing unreacted fuel is discharged from the anode. A fuel circulating path for circulating the unreacted fuel to the anode is connected to the power generating unit and fuel is supplied from the fuel supplying unit to the fuel circulating path depending on a reduction in pressure of the mixture fuel. The temperature of the power generating unit is controlled according to the concentration of the mixture fuel supplied to the anode. Consequently, a fuel cell system, which can achieve reduction of the size thereof without dropping fuel usage efficiency, can be provided.
