An object of the present invention is to provide a fuel cell system capable of avoiding damage to a circulation pump at a low temperature to improve system efficiency. The fuel cell system of the present invention includes a fuel gas circulation system having a circulation path which re-circulates, through a fuel cell, a fuel off gas discharged from the fuel cell, and a circulation pump which feeds under pressure the fuel off gas in the circulation path; and a controller which controls driving of the circulation pump. The controller stops the driving of the circulation pump at a predetermined low temperature. |
