<P>PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell power generation system, which can drastically reduce fixed cost and operational cost of the system by maintaining durability and power generating performance of the system due to stabilization of cell temperature, and to provide its operation control method. <P>SOLUTION: The system comprises: a fuel cell 9 being as a power generating cell 10 or a cell assembly by receiving fuel 8 reformed with the use of its own exhausted gas by a reformer 6 beforehand; and a control device 300 having flow volumes of cooling air A to be input for fuel cell entrance air and cooling air B to be input for reformer entrance exhaust gas as operational volume. The control device adjusts the flow volume of the cooling air A in accordance with a cell temperature T<SB>C</SB>, and the cooling air B in accordance with a reformer exit fuel temperature T<SB>F</SB>, as well as corrects the reformer exit fuel temperature in accordance with the amount of the change of the cell temperature. <P>COPYRIGHT: (C)2010,JPO&INPIT |
