Abstract
The present invention is to provide a solid oxide fuel cell capable of improving the overall energy efficiency. The present invention is directed to a solid oxide fuel cell and comprising: a fuel cell module; a fuel supply device; a combustion chamber for burning excess fuel and heating; a heat storing material, a power demand detecting sensor; a temperature detection device, and a control device for controlling so that the fuel utilization rate is high when generated power is large, and also for changing output power at a delay to the fuel supply rate; whereby the control device comprises a stored heat amount estimating circuit, and when it is estimated that a utilizable heat amount has accumulated in the heat storing material, the fuel supply rate is reduced so that the fuel utilization rate increases vs. the same generated power.
