Provided is a solid electrolyte fuel cell with an extended period in which the minimum rated output power can be maintained while inhibiting the progression of deterioration in a fuel cell module. The solid electrolyte fuel cell (1) is equipped with a fuel cell module (2), a fuel supply device (38), an oxidant gas supply device (45), and a controller (110) that controls the amount of fuel being supplied. The controller is equipped with a deterioration assessing circuit (110a) that assesses deterioration and a fuel adjusting circuit (110b) that adjusts operating conditions. The fuel adjusting circuit makes adjustments to reduce the rated output power in order to decrease the fuel supply when deterioration is deemed to have occurred in the fuel cell module, and once deterioration in the fuel cell module progresses and preset adjustment switching conditions have been reached, the fuel adjusting circuit makes adjustments to the amount of fuel being supplied to the fuel cell module in order to maintain the reduced rated output power. |
