Tail gas treatment system for hydrogen fuel cell stack test system

The invention relates to the technical field of fuel cells, in particular to a tail gas treatment system for a hydrogen fuel cell stack test system. The tail gas treatment system comprises a compressed air mechanism, a dilution catalysis mechanism, a dilution condensation device and a drainage and exhaust mechanism, wherein the dilution catalysis mechanism is communicated with the anode tail discharge of a test system and the compressed air mechanism so as to mix the tail gas of the anode tail discharge with air to form first diluted mixed gas, the dilution condensation device is communicated with the cathode tail discharge of the test system and the dilution catalysis mechanism so as to mix and dilute the first diluted mixed gas and the tail gas of the cathode tail discharge and then condense the first diluted mixed gas and the tail gas of the cathode tail discharge to form a condensed liquid and second diluted mixed gas, and the drainage and exhaust mechanism is communicated with the dilution condensation d
