A solid oxide fuel cell is provided with which the further advance of degradation can be restrained relative to fuel cell units in which degradation has advanced. The present invention is a solid oxide fuel cell (1) which varies output power in response to a required generation amount, having a fuel cell module (2) furnished with multiple fuel cell units, a fuel supply device (38) for supplying fuel to the fuel cell module, an oxidant gas supply device (45) for supplying oxidant gas to the fuel cell module, and a controller (110) for changing the amount of fuel supplied from the fuel supply means in response to the required generation amount; wherein the controller reduces the rate of change in the fuel supply amount per unit time when the required generation amount changes subsequent to an estimate or determination that the fuel cell module has degraded. |
