PROBLEM TO BE SOLVED: To provide a fuel battery system that enables a solid oxide fuel battery to be operated and stopped at suitable timings while avoiding frequent repetition of start-up and stop of the solid oxide fuel battery.SOLUTION: On a restricted condition that an under-operation period is continued by a lower limit operation period or more when a solid oxide type fuel battery 1 is under operation, an operation control device C equipped to a fuel battery system determines on the basis of transition of a system status amount as a function of past load energy to be supplied to a load portion L achieved during operation whether a fuel battery 1 should be stopped or continued to be operated. On a restricted condition that an under-stop period is continued by a predetermined lower limit stop period or more when the fuel battery 1 is stopped, the operation control device C determines on the basis of transition of the system status amount as a function of past load energy to be supplied to the load portion L achieved during stop whether the fuel battery 1 should be operated or continued to be stopped.SELECTED DRAWING: Figure 1 |
