摘要:
A fuel cell system (11) has different allowable changes per unit time in an operation range of a fuel cell (14), in both a first output range of the fuel cell (14) and a second output range of the fuel cell (14), the second output range being lower than the first output range. The allowable change per unit time in the output of the fuel cell (14) in the second output range is smaller than the allowable change per unit time in the output of the fuel cell (14) in the first output range.
