Abstract:
1. A fuel cell system comprising: a fuel cell; a gas supply source of a supply gas; a supply path for supplying the supply gas from the gas supply source to the fuel cell; a control device that controls the fuel cell system; a circulation path for returning a circulation gas discharged from the fuel cell to the supply path; a joining part at which the supply gas meets the circulation gas; and a circulation device configured to control the flow rate of the circulation gas to be fed to the joining part, wherein the control device is programmed to set a flow rate of the circulation gas with respect to that of the supply gas in consideration of condensation latent heat of water vapor in the circulation gas, so that a temperature of a combined gas constituted by combining the supply gas and the circulation gas is higher than a predetermined temperature.
