PROBLEM TO BE SOLVED: To solve the problem in the operation control of a fuel cell system that when the fuel cell system cannot start power generation at a scheduled power generation start time because the temperature of the hot water storage tank is high and power generation is disabled, such as when the tank is filled, activation of the fuel cell system is delayed and the duration of power generation is shortened, and that when the length of power generation time is less than an expected time, resource saving, environment burden and economy of power generation become worse than when the fuel cell is not activated.SOLUTION: To solve the conventional problem, the present invention sets a shortest power generation time which is a minimum value of power generation time with which resource saving or environmental or economical merits can be secured, as compared with the case where the fuel cell is not activated. When a duration until a stop time becomes shorter than the shortest power generation time, the fuel cell system is not activated or the stop time is extended so that the shortest power generation time can be fulfilled. |
