A solid oxide fuel cell system includes: an igniting portion (8) configured to ignite a raw material when starting up the solid oxide fuel cell system; a raw material supply portion (10) configured to supply the raw material; a reforming air supply portion (11) configured to supply reforming air; and an electric power generation air supply portion (12) configured to supply electric power generation air. When starting up the solid oxide fuel cell system, the raw material supply portion (10) supplies the raw material, and the electric power generation air supply portion (12) supplies the electric power generation air. The igniting portion (8) ignites the raw material. After the ignition, the preforming air supply portion (11) 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.
