The invention relates to the technical field of fuel cell vehicles, in particular to a fuel cell vehicle tail gas and water vapor separation and emission system and a control method thereof. The tailgas and water vapor separation and emission system comprises a fuel cell stack, a tail gas conveying pipe, a water tank, a fuel cell control unit, a first control switch, an exhaust pipe and a drain pipe, one end of the tail gas conveying pipe is communicated with the tail gas output end of the fuel cell stack, and the other end of the tail gas conveying pipe is communicated with a gas inlet of the water tank; the exhaust pipe is communicated with a gas outlet of the water tank, a filter unit is arranged at one end, far away from the water tank, of the exhaust pipe, the filter unit is used forfiltering gas, the drain pipe is communicated with a water outlet of the water tank, and the first control switch is arranged on the drain pipe and used for connecting or disconnecting the drain pipe. Liquid separated by the system is collected in a centralized mode, regular and fixed-point drainage is conducted, and the problem that in the prior art, tail gas is discharged at will, and consequently the road surface environment is affected is solved.

    本发明涉及燃料电池汽车技术领域,尤其涉及燃料电池汽车尾气水汽分离和排放系统及其控制方法。该尾气水汽分离和排放系统,包括燃料电池堆、尾气输送管、水箱、燃料电池控制单元、第一控制开关、排气管和排水管,所述尾气输送管的一端与所述燃料电池堆的尾气输出端连通,其另一端与所述水箱的进气口连通,所述排气管与所述水箱的出气口连通,且其远离所述水箱的一端设有过滤单元,所述过滤单元用于对气体进行过滤处理,所述排水管与所述水箱的出水口连通,所述第一控制开关设置在所述排水管上,其用于连通或断开所述排水管。该系统分离出来的液体进行集中收集,并进行定期和定点排水,解决了现有技术中尾气随意排放对路面环境造成的影响。
