A fuel cell system includes a fuel cell stack; a diluted fuel tank for storing diluted fuel; a diluted fuel conduit for supplying the diluted fuel from the fuel dilution tank to the fuel cell stack; a differential pressure sensor in the diluted fuel conduit to sense a differential pressure resulting from a fuel flow inside the diluted fuel conduit and to transmit an electric signal; and a controller for receiving the electric signal from the differential pressure sensor and for determining whether or not fuel is flowing inside the diluted fuel conduit.
