[0033] The structure and power system topology of the present invention are as figure 2 and image 3As shown, the system has two power sources, namely fuel cell stack and lithium battery. The output terminal of the fuel cell stack 2 is connected with the relay, the anti-reverse diode (integrated with the sensor in the electronic component box 7) and the power resistor 6 in sequence, and then connected in parallel with the lithium battery pack 4. When the system works, the fuel cell stack 2 and the lithium battery The battery packs work together to power the motors. The hydrogen supply system of the system is arranged in the space under the pedals of the motorcycle. The hydrogen storage scheme of the high-pressure hydrogen storage tank is adopted. The hydrogen in the tank is decompressed by the two-stage pressure reducing valve to supply gas to the anode of the electric stack. Since the electric stack is air-cooled The type cathode is open, so the supply of oxygen is realize...
