PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell that stably controls an interior temperature of a fuel cell module while reducing waste of fuel.SOLUTION: A solid oxide fuel cell (1) includes: a fuel cell module (2); fuel supply means (38); temperature detection means (142); and control means (110) that controls interior temperature of the fuel cell module (2) on the basis of detected temperature. The control means (110) has: first temperature control means (110a) that, when the detected temperature leaves a first temperature range, exercise such control that the detected temperature enters a second temperature range on the inside of the first temperature range; and second temperature control means (110b) that, when once the detected temperature enters the second temperature range, exercises such control that the detected temperature is to be maintained. When the detected temperature enters the second temperature range, the temperature control is switched from the first temperature control means (110a) to the second temperature control means (110b). When the detected temperature leaves the first temperature range, the temperature control is switched to the first temperature control means (110a) |
