本发明公开了一种燃料电池尾排装置、燃料电池系统及燃料电池汽车,涉及新能源汽车技术领域。燃料电池尾排装置包括排氢阀、混排管路和弥散排氢管,弥散排氢管连通排氢阀,从而将排氢阀排出的氢气排入弥散排氢管的内部,弥散排氢管的管壁设有多个弥散孔,弥散孔连通弥散排氢管的内部和混排管路,从而可将弥散排氢管内部的氢气排入混排管路,降低氢气排入混排管路的流速,拉长氢气从排氢阀到尾排口的排放时间,使得氢气与混排管路中的尾排空气的混合更充分,将氢气更好地稀释,最终降低尾排氢气的浓度。
The invention discloses a fuel cell tail exhaust device, a fuel cell system and a fuel cell automobile, and relates to the technical field of new energy automobiles. The fuel cell tail discharging device comprises a hydrogen discharging valve, a mixed discharging pipeline and a dispersion hydrogen discharging pipe, the dispersion hydrogen discharging pipe is communicated with the hydrogen discharging valve, so that hydrogen discharged by the hydrogen discharging valve is discharged into the dispersion hydrogen discharging pipe, a plurality of dispersion holes are formed in the pipe wall of the dispersion hydrogen discharging pipe, and the dispersion holes are communicated with the interior of the dispersion hydrogen discharging pipe and the mixed discharging pipeline. Therefore, hydrogen in the dispersion hydrogen discharging pipe can be discharged into the mixed discharging pipeline, the flow speed of the hydrogen discharged into the mixed discharging pipeline is reduced, the discharging time of the hydrogen from the hydrogen discharging valve to the tail discharging port is prolonged, the hydrogen and tail discharging air in the mixed discharging pipeline are mixed more sufficiently, the hydrogen is diluted better, and finally the concentration of the tail discharging hydrogen is reduced.
