<p>A fuel cell stack has a built-in sensor MEA including: a sensor ion exchange membrane; an anode to which part of fuel supplied to the fuel cell stack flows in, the anode being arranged on one side of the sensor ion exchange membrane; and a cathode from which the part of the fuel supplied to the fuel cell stack flows out, the cathode being arranged on the other side of the sensor ion exchange membrane. An external power supply applies a predetermined potential difference to between the anode and the cathode. A current occurring from electrolysis of the fuel is measured by using an ammeter.</p> |
