The invention discloses a resistance reduction system of a fuel cell automobile, the fuel cell automobile and a resistance reduction method of the fuel cell automobile. The fuel cell automobile comprises an automobile body and the drag reduction system, the drag reduction system comprises a fuel cell stack, and the fuel cell stack is provided with a water outlet; the water recovery device is connected with the water outlet; the first water pump assembly is connected with the water recovery device; and the jet atomization device is connected with the first water pump assembly. The invention discloses a resistance reduction method for a fuel cell automobile. The method comprises the following steps: step a, recovering water of a fuel cell stack by using a water recovery device; and b, water is pumped out to a spraying atomization device through a first water pump assembly, and water vapor is formed through the spraying atomization device and sprayed out to the rear portion of the fuel cell automobile. The pressure of the low-pressure area rises again, the pressure difference between the positive-pressure area in front of the automobile and the low-pressure area at the tail of the automobile is reduced, and the pressure difference resistance serving as main air resistance is effectively reduced, so that the pneumatic resistance is reduced.

    本发明公开了燃料电池汽车减阻系统、燃料电池汽车及其减阻方法。燃料电池汽车,包括车体和减阻系统,减阻系统包括燃料电池电堆,燃料电池电堆设有水出口;水回收装置,水回收装置与水出口连接;第一水泵组件,第一水泵组件与水回收装置连接;喷射雾化装置,喷射雾化装置与第一水泵组件连接。燃料电池汽车减阻方法,具有以下步骤:步骤a:使用水回收装置对燃料电池电堆的水进行回收;步骤b:通过第一水泵组件将水泵出至喷射雾化装置并通过喷射雾化装置形成水汽向燃料电池汽车的后方喷出。使低压区的压力回升,汽车前方的正压区与尾部的低压区之间的压差减小,作为主要空气阻力的压差阻力被有效降低,以实现了气动阻力的减低。
