The invention discloses a hydrogen fuel cell exhaust system and an automobile. The exhaust system comprises an exhaust pipeline provided with a silencer, and the exhaust pipeline is provided with a gas-water separation structure at the upstream of the silencer; the gas-water separation structure comprises a pipeline flaring part, a polymerization turbulator and an automatic drainage structure, and the caliber of the gas outlet end of the pipeline flaring part is larger than that of the gas inlet end of the pipeline flaring part so that water in the gas flow can be separated out; the polymerization turbulator is arranged in the pipeline flaring part and used for enabling airflow to do centrifugal motion through turbulent flow, separating gas from water and enabling the separated water to flow to a drainage area along the inner wall of the exhaust pipeline; the automatic drainage structure is arranged in the drainage area and used for discharging water accumulated in the drainage area outwards. The exhaust system has the functions of gas-water separation and drainage, moisture can be prevented from being accumulated in the silencer to interfere with noise reduction, the influence of water in exhausted gas on the silencer is reduced to the minimum, and the performance and efficiency of the exhaust system are improved.

    本发明公开了一种氢燃料电池排气系统及汽车,所述排气系统包括设有消音器的排气管路,所述排气管路在所述消音器的上游设有气水分离结构;所述气水分离结构包括管路扩口部、聚合扰流器以及自动排水结构,所述管路扩口部的出气端口径大于其进气端口径,以析出所述气流中的水;所述聚合扰流器设于所述管路扩口部的内部,用于通过扰流使气流做离心运动,将气体和水分离,并使分离的水沿所述排气管路的内壁流向排水区;所述自动排水结构设于所述排水区,用于将所述排水区蓄积的水向外排出。该排气系统具有气水分离和排水功能,可避免水分在消音器中积聚干扰消音,使排气中的水对消音器的影响降低最低,提高了排气系统的性能和效率。
