A stack of disc-type fuel cells and disc-type separators stacked alternately is housed in a casing. A fuel supply part extends through the central part of the upper wall of the casing to supply fuel to the central part of the stack. An air supply part extends through the central part of the lower wall of the casing to supply air to the central part of the stack. A fuel discharge part extends through the central part of the lower wall of the casing to discharge fuel after power generation. An exhaust discharge part extends through the peripheral part of the lower wall of the casing to discharge an exhaust gas resulting from the combustion of mixture of the fuel after power generation and air, and a recirculation part for mixing the fuel after power generation discharged from the fuel discharge part with newly-supplied fuel.
