<P>PROBLEM TO BE SOLVED: To provide a power generator, utilizing a direct flame type fuel cell where thermal shocks to a solid oxide fuel cell are relaxed by adjusting the flame supply, and the occurrence of cracks and peeling is suppressed. <P>SOLUTION: The power generator uses a solid oxide fuel cell C having a solid oxide substrate 1, a cathode electrode layer 2 formed on one face, and an anode electrode layer 3 formed on the opposite side face, and supplies flame f2 by combustion of a mixed gas by a gas combustion burner 4 to the anode electrode layer, and adjusts the supply status of the flame by a mixed gas producing device 8. The status of flame at the time of operation start or operation stop is changed, by adjusting a mixture ratio of a fuel gas F and air A to be supplied to a gas buffer container 81, and the speed of temperature rise or temperature drop of the solid oxide fuel cell is adjusted. Adjustment of flame supply status can be also made, by changing the spacing between the solid oxide fuel cell and the gas combustion burner. <P>COPYRIGHT: (C)2007,JPO&INPIT |
