A fuel cell module (12) includes a fuel cell stack (24), a partial oxidation reformer (45) for reforming a mixed gas of a raw fuel and an oxygen-containing gas, a steam reformer (46) for reforming a mixed gas of the raw fuel and water vapor, an evaporator (48) for supplying water vapor to the steam reformer (46), a heat exchanger (50) for raising the temperature of the oxygen-containing gas by heat exchange with a combustion gas, and an exhaust gas combustor (52) for producing the combustion gas. A fuel gas discharge chamber (62b) of the steam reformer (46) is connected to a fuel gas supply passage (44a) of the fuel cell stack (24) through a fuel gas channel (66), a fuel gas outlet (61b) of the partial oxidation reformer (45) is connected to a mixed gas supply chamber (62a) of the steam reformer (46) through a fuel gas pipe (60c), and a water vapor pipe (74b) extending from the evaporator (48) is merged to the fuel gas pipe (60c). |
