Zusammenfassung:	A controller in a fuel cell system operates a fuel cell in a normal mode or in a special mode. In the normal mode, the fuel cell is operated to satisfy at least one of a first operation condition and a second operation condition, under the first operation condition an operation time of the fuel cell per unit period is equal to or shorter than a unit allowable operation time, under the second operation condition the number of times of operation of the fuel cell per unit time is equal to or less than a unit allowable number of times of operation, and in the special mode, the fuel cell is operated without being limited by at least one of the first operation condition and the second operation condition.
