Problem: To provide a fuel cell module and a fuel cell device with improved power output.Resolution means: A fuel cell module (27) according to the present invention includes: a housing (2); a plurality of cell stack devices (1) arranged inside the housing (2), each cell stack device (1) including a cell stack (3) in which a plurality of fuel cells (2) that generate power using fuel gas and oxygen-containing gas are arranged; and exhaust gas discharge paths (39, 40) formed between the cell stack devices (1) for discharging the exhaust gas from the fuel cells. Consequently, the exhaust gases can be efficiently discharged, thereby improving the power output. A fuel cell device (52) can have improved power output by being provided with the above-described fuel cell module (27).
