<p>In control over an oxygen sensor, a temperature of the oxygen sensor, which detects a concentration of oxygen in exhaust gas from a combustion chamber in which anode off-gas of a fuel cell is burned, is adjusted to a target temperature, and an output of the oxygen sensor is calibrated. When the temperature of the oxygen sensor is adjusted to the target temperature, a plurality of the target temperatures are set, a calibration target temperature higher than or equal to a first predetermined temperature is selected from among the plurality of target temperatures when the output of the oxygen sensor is calibrated, and a target temperature, which is lower than the calibration target temperature, is selected from among the plurality of target temperatures during power generation of the fuel cell.</p> |
