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.
