PROBLEM TO BE SOLVED: To provide a solid oxide fuel battery system in which maximum temperature of an individual power generation cell can be estimated without using a temperature sensor.SOLUTION: A control device 103 includes a cell state calculation part 108 for calculating a maximum temperature of each fuel battery cell 110 using a temperature and flow rate of a fuel gas, a temperature and flow rate of an oxidant gas, and a current value of current extracted from a fuel battery stack 101 which are set by an input part 104a. When maximum temperatures of all fuel battery cells 110 are equal to or smaller than a predetermined threshold, the control device 103 cause a fuel gas supply device 107 to supply a fuel gas having the temperature and flow rate set by the input part 104a, causes an oxidant gas supply device 106 to supply an oxidant gas having the temperature and flow rate set by the input part 104a, and causes a power supply device 102 to supply current having the current value set by the input part 104a. |
