<P>PROBLEM TO BE SOLVED: To provide a solid electrolyte fuel cell (SOFC) in which a fuel battery cell is made adaptable to a preferable state even when there is an individual difference of the fuel battery cell or a change of an outer air environment or the like when a power generation output is changed to follow a load. <P>SOLUTION: The SOFC for changing a power generation output value in response to a demanded power generation amount includes, a fuel battery cell 84 disposed in a power generation chamber 10, a fuel flow rate control unit 38 which supplies fuel to the fuel battery cell, a power generation chamber temperature sensor 142 which measures a temperature (T1) in the power generation chamber, and a control part 110 which changes the amount of fuel supply in response to the demanded power generation amount and based on fuel supply control characteristics. The control part includes a lower limit temperature value (Ta) and an upper limit temperature value (Tb), and further includes an adaptive control means which corrects the amount of fuel supply based on signals form the power generation chamber sensor so that the power generation chamber temperature (T1) is held in a temperature monitoring zone when the power generation chamber temperature (T1) is out of the temperature monitoring zone. <P>COPYRIGHT: (C)2011,JPO&INPIT |
