摘要： A fuel cell system according to the present invention is characterized by comprising a measurement unit which measures an impedance of a fuel cell in a predetermined frequency region, and a regulation unit which regulates an amount of a gas to be supplied to the fuel cell based on a measured value of the impedance in the predetermined frequency region. According to such a constitution, the impedance of the fuel cell in the predetermined frequency region (e.g., a low frequency region) is measured, and the amount of the gas (e.g., an amount of an oxidizing gas) to be supplied to the fuel cell is regulated based on this measured value of the impedance. Here, since the impedance of the fuel cell in the predetermined frequency region largely differs with a fuel supply state (see FIG. 2), the amount of the gas to be supplied to the fuel cell can be regulated based on the measured value of the impedance to realize a highly efficient and stable operation.

摘要： It is prevented that when a system is left unused, carried carbon ion a cathode-side catalyst to lower a power generation performance. The molar quantities of hydrogen and oxygen in a fuel gas supply/discharge system and an oxidizing gas supply/discharge system with respect to a fuel cell are calculated, and control is performed so that the molar ratio of hydrogen and oxygen which can chemically be reacted in a fuel gas and an oxidizing gas during the stop of the fuel cell is 2 or more. Hydrogen is preferably supplied in accordance with the magnitude of a cell voltage in the fuel cell so as to maintain the molar ratio. Moreover, a gas passage in the oxidizing gas supply/discharge system is preferably provided with an inlet valve and an outlet valve for sealing the oxidizing gas in the gas passage.
