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, an exhaust gas combustor for combusting a fuel exhaust gas and an oxygen-containing exhaust gas discharged from the fuel cell stack thereby to produce a combustion gas, and a heat exchanger for raising the temperature of the oxygen-containing gas by heat exchange with the combustion gas. The heat exchanger is provided on one side of the fuel cell stack, and the partial oxidation reformer and the exhaust gas combustor are provided on the other side of the fuel cell stack. The partial oxidation reformer is provided so as to surround the exhaust gas combustor.
