A solid oxide fuel cell (SOFC) device comprises a fuel cell assembly (12), a reformer (20), a fuel gas supply device (38), a reforming air supply device (44), a power generating air supply device (45), an ignition device, a temperature detection devices for detecting the temperature caused by combustion of fuel gas, and a control section (52) for sequentially conducting a combustion operation in which fuel gas is ignited by the ignition device and combusted using the power generating air, a POX operation, an ATR operation, and an SR combination, wherein the control section (52) determines that a flameout has occurred when the amount by which the temperature caused by combustion of fuel gas and detected by the temperature detection device drops within a predetermined time is equal to or greater than a preset, predetermined temperature drop threshold, and the predetermined temperature drop threshold is set as a plurality of predetermined temperature drop thresholds in accordance with temperature bands caused by the combustion of fuel gas, the lower the temperature induced by the combustion of fuel gas, the higher is the temperature drop threshold. |
