Abstract
A fuel cell system includes: a steam generator configured to heat water to generate steam; a reformer configured to cause a reaction between the steam and hydrocarbon to generate a reformed gas; a fuel cell stack, which has an anode and a cathode, and is configured to generate electric energy through an electrochemical reaction caused between the reformed gas and an oxidant; and an ejector configured to supply at least one of a raw material containing the hydrocarbon or an anode circulating gas. The steam generator includes: an evaporation flow passage through which the water flows; an anode exhaust gas flow passage that is thermally connected to the evaporation flow passage and through which the anode exhaust gas flows; and an auxiliary heating device configured to heat the water. The anode exhaust gas flow passage and the auxiliary heating device are opposed to each other across the evaporation flow passage.
