To provide a solid oxide fuel cell capable of extending the time period over which a minimum rated output power can be maintained while restraining the advance of fuel cell module degradation. The present invention is a solid oxide fuel cell (1), having a fuel cell module (2), a fuel supply device (38), an oxidant gas supply device (45), and a controller (110); wherein the controller is furnished with a degradation determining circuit for determining degradation (110a) and a fuel correction circuit for correcting operating condition (110b); in which the fuel correction circuit executes a correction to reduce rated output power so that the fuel supply amount is reduced when a determination is made that the fuel cell module has degraded, and when degradation of the fuel cell module advances and predetermined correction switching condition is satisfied, the fuel correction circuit corrects the fuel supply amount supplied to the fuel cell module so as to maintain the reduced rated output power.
