Abstract: A fuel cell module includes: a housing; a cell stack; a reformer; and an oxygen-containing gas supply section. The cell stack comprises fuel cells which are arranged along a predetermined arrangement direction, and is housed in the housing. The reformer is disposed above the cell stack in the housing. The oxygen-containing gas supply section is disposed along the predetermined arrangement direction of the fuel cells so as to face the cell stack and the reformer, and has a gas flow channel through which an oxygen-containing gas to be supplied to the fuel cell flows downwardly. Moreover, in the oxygen-containing gas supply section, the gas flow channel has a first region and a second region which is greater than the first region in flow channel width in a direction perpendicular to a direction in which an oxygen-containing gas flows, and the predetermined arrangement direction of the fuel cells.
