ABSTRACT:
A fuel cell discharge-gas processing device includes: an anode off-gas introduction path which introduces an anode off-gas discharged from an anode of a fuel cell; a dilution container which is connected to the anode off-gas introduction path, and into which the anode off-gas is introduced; and a bypass path which branches off from a cathode gas supply path for supplying a cathode gas to a cathode of the fuel cell, and is connected to the dilution container so as to bypass the fuel cell. While the fuel cell is in operation, the cathode gas supplied from the bypass path into the dilution container is discharged to an exterior of the dilution container.
