Claim Text:
1. A fuel cell system comprising: a reformer which reforms a feedstock to produce a reformed gas; a feedstock supplying section which supplies the feedstock to the reformer; a fuel cell which generates electricity using a fuel gas contained in the reformed gas; a burner section which combusts fuel gas that was not consumed in electricity generation in the fuel cell to heat the reformer; a carbon monoxide sensor being situated between the burner section and a catalytic unit that reduces a concentration of carbon monoxide contained in effluent gases discharged from the burner section; and a control portion programmed to control a feed rate of the feedstock supplied from the feedstock supplying section to the reformer, wherein the control portion is programmed to: determine one temperature of the burner section based on a concentration or amount of a carbon monoxide contained in effluent gases discharged from the burner section sensed by the carbon monoxide sensor, and maintain a temperature of the reformer within a prescribed temperature range appropriate for reforming the feedstock by controlling the feed rate of the feedstock based only on the determined one temperature.
