PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell in which the generation power followability for the demand power is enhanced while minimizing deterioration of fuel cell stack.SOLUTION: The solid oxide fuel cell includes a fuel cell module, a reformer, fuel supply means, water supply means, oxidizer gas for power generation supply means, and control means for generating a power corresponding to the demand power. The control means includes first delay control means for increasing the generation power with a delay after increasing the supply amount of water, oxidizer gas and fuel when increasing the generation power, and second delay control means for increasing the generation power with a delay after increasing the supply amount of water, oxidizer gas and fuel more rapidly than the first delay control means, and increasing the generation power more gently than increase of fuel supply. The first and second delay control means are used while being switched. |
