摘要： A fuel cell system includes a fuel cell, an impedance measuring instrument, and a control device. The control device is connected to the impedance measuring instrument. The impedance measuring instrument measures the impedance of the fuel cell according to the AC impedance method. The control device stores in advance a reference value corresponding to a reference hydrogen concentration. The control device compares the real part Z′ of impedance acquired via the impedance measuring instrument against the reference value. When Z′ is equal to or greater than the reference value, the control device estimates the hydrogen concentration of the fuel cell to be equal to or less than the reference hydrogen concentration.
