Abstract: A fuel cell system includes: a fuel cell; a reformer to generate a hydrogen-containing gas; an electric power generation raw material supply unit; a reforming material supply unit configured to supply at least one of reforming water and reforming air, to the reformer; an oxidizing gas supply unit to supply an oxidizing gas to a cathode of the fuel cell; a combustor to ignite an exhaust gas discharged from the fuel cell; and a controller. In an operation stop process of the fuel cell system, the controller causes the oxidizing gas supply unit to supply the oxidizing gas, causes the electric power generation raw material supply unit and the reforming material supply unit to intermittently supply the electric power generation raw material and at least one of the water and the air to the reformer, and causes the ignitor to perform an ignition operation.

Abstract: A solid oxide fuel cell system includes: an igniting portion configured to ignite a raw material when starting up the solid oxide fuel cell system; a raw material supply portion configured to supply the raw material; a reforming air supply portion configured to supply reforming air; and an electric power generation air supply portion configured to supply electric power generation air. When starting up the solid oxide fuel cell system, the raw material supply portion supplies the raw material, and the electric power generation air supply portion supplies the electric power generation air. The igniting portion ignites the raw material. After the ignition, the reforming air supply portion supplies the reforming air. With this, the safety can be increased in consideration of characteristics in respective phases from the start-up of the solid oxide fuel cell system until the electric power generation.
