[0022] In order to make the content of the utility model more easily be clearly understood, the following according to specific embodiment and combining with the drawings, the utility model is further explained in detail.

[0023] As Figures 1-3 Indicated in the present embodiment, a new hydrogen power system is provided, which mainly consists of hydrogen storage assembly 1 and fuel cell assembly 2. Among them, hydrogen storage assembly 1 contains lower pipe 10 and hydrogen storage bottle 11 arranged in lower pipe 10, fuel cell assembly 2 contains battery box 20 communicated with the bottom end of lower pipe 10, fuel cell 21 arranged in battery box 20 and cooling fan 22 installed on the side of fuel cell 21 close to lower pipe 10.

[0024] Specifically, installation slope 200 parallel to lower pipe 10 is provided on the front side of battery box 20, and fuel cell 21 is installed on the inside of installation slope 200 through support frame 24, and controller 210 is further arranged above fuel cell 21; air outlet 202 is opened at the communication place of battery box 20 and lower pipe 10, and a plurality of air inlets 201 are opened on the bottom surface adjacent to installation slope 200 of battery box 20. Hydrogen storage bottle 11 releases hydrogen through hydrogen outlet, and supplies fuel cell 21 through pipeline to generate chemical reaction and produce electric energy; and fuel cell 21 generates a large amount of heat through chemical reaction, and the heat is blown to air outlet 202 in the form of hot air through cooling fan 22, the hot air is blown to hydrogen storage bottle 11 through air outlet 202, and then the surface of hydrogen storage bottle 11 is heated, the surface temperature of hydrogen storage bottle 11 is improved, and the hydrogen release efficiency of hydrogen storage bottle 11 is improved, without additional heating device for hydrogen storage bottle, saving resources and improving energy utilization rate.

[0025] The above installation slope 200 is to better drain water, and threading hole 203 close to the inside of installation slope 200 is further opened at the connection place of battery box 20 and lower pipe 10 in the present embodiment, threading hole 203 can be used to thread brake lines, electric wires, hydrogen pipes and other wire harnesses on one hand, and can also drain the rainwater entering lower pipe 10 on the other hand, and the slope is more conducive to the rainwater to be drained out of battery box 20 through air inlet 201, reduces the risk of water accumulation in battery box 20, and effectively improves the waterproof performance without increasing the space.

[0026] The plurality of air inlets 201 on the bottom of the battery box 20 can make air enter the battery box 20 through the air inlets 201 and finally be sucked into the fuel cell 21 to participate in chemical reaction, which is convenient to operate; meanwhile, the air inlets 201 are located on the bottom of the battery box 20, which can reduce the rainwater entering the battery box and improve the waterproof performance of the battery box.
