    • A fuel cell system characterized by comprising a means for measuring the impedance of a fuel cell in a predetermined frequency region, and a means for regulating the quantity of gas being supplied to the fuel cell based on the measurement of impedance in the predetermined frequency region. Impedance of a fuel cell is measured in a predetermined frequency region (e.g. low frequency region) and then the quantity of gas (e.g. the quantity of oxidizing gas) being supplied to the fuel cell is regulated based on the measurement of impedance. Since the impedance of a fuel cell in a predetermined frequency region differs significantly depending on the fuel supply state (refer to Fig. 2), high efficiency and stable operation can be achieved by regulating the quantity of gas being supplied to the fuel cell based on the measurement of impedance.
