Abstract:
1. A fuel cell system comprising: a reformer configured to generate a hydrogen-containing gas through a reforming reaction by using a raw material and steam; a raw material supply device configured to supply the raw material to the reformer; a steam supply device configured to supply the steam to the reformer; a temperature detector configured to detect a temperature of the reformer; a fuel cell configured to generate electric power by using the hydrogen-containing gas; a combustor configured to combust the hydrogen-containing gas discharged from the fuel cell to heat the reformer; and a controller configured to, while controlling the raw material supply device such that the temperature detected by the temperature detector becomes a target temperature, control the steam supply device in accordance with a change in a composition of the raw material, such that a change rate of a steam supply amount to the reformer becomes less than a change rate of a raw material supply amount to the reformer.
