Abstract:
1. A fuel cell system comprising: a hydrogen generator including a reformer configured to generate a hydrogen-containing gas by a reforming reaction using a raw material; a fuel cell configured to generate electric power using the hydrogen-containing gas supplied from the hydrogen generator; a combustor configured to combust an anode off gas discharged from the fuel cell to heat the reformer; a CO detector configured to detect a carbon monoxide concentration of the flue gas discharged from the combustor; an electric heater configured to heat the CO detector; and a controller, wherein the controller is configured to detect a difference between an amount of power consumption of an electric power load and an amount of electric power generated by the fuel cell, and to increase an amount of energization to the electric heater during an electric power generation operation of the fuel cell system in a case where the detected difference is larger than a threshold value.
