A fuel cell module according to the present embodiment includes a hydrodesulfurizer, a cell stack, an exhaust gas channel portion, and an air-preheating channel portion. The hydrodesulfurizer is configured to desulfurize fuel gas using a hydrodesulfurization catalyst. A reformer is configured to generate a hydrogen-containing gas. The cell stack is constituted by stacking a plurality of fuel cells and is configured to generate electric power. The exhaust gas channel portion is configured to discharge the hydrogen-containing gas, and discharge exhaust gas that is generated by the combustion of the oxygen-containing gas. The air-preheating channel portion is an air-preheating channel portion that is disposed so as to be adjacent to the exhaust gas channel portion and that is configured to preheat the oxygen-containing gas through heat exchange with the exhaust gas channel portion. The air-preheating channel portion is disposed between the hydrodesulfurizer and the cell stack.
