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.

Abstract: A fuel cell system includes: a reformer generating a reformed gas using a raw material; a fuel cell generating electric power; a raw material supply passage; a hydro-desulfurizer operative to remove sulfur component in the raw material; a recycle passage through which the reformed gas is supplied to the raw material supply passage provided upstream of the hydro-desulfurizer; a temperature detector detecting a temperature of the hydro-desulfurizer; and a controller, wherein: when the temperature of the hydro-desulfurizer reaches a predetermined temperature, the controller increases a flow rate of the raw material from a predetermined flow rate by a flow rate corresponding to a flow rate of the recycled gas, and then, the controller starts supplying the recycled gas to the recycle passage; and after the recycled gas reaches an upstream end of the recycle passage, the controller returns the flow rate of the raw material to the predetermined flow rate.
