A fuel cell module includes a fuel cell stack, a partial oxidation reformer for reforming a mixed gas of a raw fuel and an oxygen-containing gas, a steam reformer for reforming a mixed gas of the raw fuel and water vapor, an evaporator for supplying water vapor to the steam reformer, a heat exchanger for raising the temperature of the oxygen-containing gas by heat exchange with a combustion gas, and an exhaust gas combustor for producing the combustion gas. A fuel gas discharge chamber of the steam reformer is connected to a fuel gas supply passage of the fuel cell stack through a fuel gas channel, a fuel gas outlet of the partial oxidation reformer is connected to a mixed gas supply chamber of the steam reformer through a fuel gas pipe, and a water vapor pipe extending from the evaporator is merged to the fuel gas pipe. |
