Abstract
A fuel cell discharge-gas processing device that dilutes anode off-gas discharged from a fuel cell anode by mixing the anode off-gas with a diluent gas so as to produce a diluted gas and then discharges mixture of the anode off-gas and the diluent gas, includes: a dilution container; an anode off-gas introduction path; a diluent gas path through; a diluent gas emission hole; a mixed gas discharge hole; at least one partition panel; and a communication gas path, wherein the anode off-gas emission hole is provided so as to emit anode off-gas toward the partition panel.

A fuel cell discharge-gas processing device that dilutes anode off-gas discharged from a fuel cell anode by mixing the anode off-gas with a diluent gas so as to produce a diluted gas and then discharges mixture of the anode off-gas and the diluent gas, comprising:
- a dilution container;
- an anode off-gas introduction path having an anode off-gas emission hole that emits the anode off-gas to inside the dilution container;
- a diluent gas path through which the diluent gas flows, having drain holes for discharging liquid inside the dilution container;
- a diluent gas emission hole, communicating to the diluent gas path, that emits the diluent gas flowing through the diluent gas path to inside the dilution container;
- a mixed gas discharge hole, communicating to the diluent gas path, that discharges mixed gas of the anode off-gas and the diluent gas mixed inside the dilution container more to the downstream side of the diluent gas path than the communication portion with the diluent gas emission hole;
- at least one partition panel, provided inside the dilution container, that divides the dilution container into an upstream chamber in which the anode off-gas introduction path and the diluent gas emission hole communicate, and a downstream chamber in which the mixed gas discharge hole communicates;
- and
- a communication gas path that communicates with the upstream chamber and the downstream chamber,
- wherein the anode off-gas emission hole is provided so as to emit anode off-gas toward the partition panel.
