The invention provides a hydrogen fuel cell automobile exhaust device. The device comprises a cylinder body and a connecting pipe fixed in the middle of the left end of the cylinder body, wherein a conical cover with a large left part and a small right part is arranged at the right end of the cylinder body; a fixing ring is arranged on the annular outer side of the cylinder body; the left end of the conical cover is in threaded connection with a fixing ring; at least two fixing plates are equidistantly fixed between the fixing ring and the left part of the cylinder body; a main shaft arrangedleft and right is rotationally connected to the middle position in the cylinder body; fixed covers are arranged at the left and right ends of the main shaft; the two fixed covers are respectively arranged in the cylinder body and the conical cover; and the annular outer end of each fixed cover is equidistantly fixedly connected with at least fan blades. Compared with like devices in the prior art,the device of the invention has the following beneficial effects: hydrogen and water vapor in waste gas are uniformly mixed through the fan blades, the waste gas is also mixed with outside air, the concentration of hydrogen in the waste gas is reduced, high-concentration hydrogen is prevented from being generated at an exhaust port, and the safety is improved.

    本发明提供一种氢燃料电池汽车排气装置,包括筒体以及固定在筒体左端中间位置的连接管,所述筒体右端设置左大右小布置的锥形罩,所述筒体环形外侧设置固定环,所述锥形罩左端螺纹连接固定环,所述固定环与筒体左部之间等距固定至少两个固定板,所述筒体内部中间位置转动连接左右布置的主轴,所述主轴左右两端均设置固定盖,且两个固定盖分别设置在筒体内部以及锥形罩内部,所述固定盖环形外端等距固定连接至少四个扇叶,与现有技术相比,本发明具有如下的有益效果:通过扇叶将废气中氢气和水蒸气进行均匀混合,也将废气与外界空气进行混合,降低废气中氢气浓度,防在排出口产生高浓度氢气,提升安全性。
