The quantity of reaction gas supplied can be efficiently controlled while reducing the work. A control unit judges whether or not the atmospheric pressure detected value detected by an atmospheric pressure sensor continues to be out of a range from 0.6 V to 4.48 V for 50 ms or more. If the detected atmospheric pressure does not continue to be out of the range for 50 ms or more, the detected atmospheric pressure is converted into an atmospheric pressure value and passed through a low-pass filter. Thus, an atmospheric pressure corrected value is outputted. Contrarily, if the atmospheric pressure continues to be out of the range for 50 ms or more, an alternative value of 101.3 kPa.abs is outputted as the atmospheric pressure corrected value. Pressure detected values detected by pressure sensors are converted into gate pressure values, respectively. Absolute pressures of the reaction gas in the oxidizing gas piping system and the hydrogen gas piping system are determined by calculation by adding the atmospheric pressure corrected value to the gate pressure values. According to these absolute pressures, the quantity of reaction gas supplied to the fuel battery is controlled. |
