[0020] Through the above technical solution: during installation, the original electric bicycle battery placement box 1 is removed from the bicycle, and the through hole 12 is processed in the front and rear lower parts of the box 1. After the ventilation mesh plate 5 is installed inside the through hole 12, the fuel cell system 6 is fixedly set on one side of the bottom of the box 1, and then four supporting angle pieces 3 are installed on the left and right sides of the inner wall of the box 1 by screws 7 through and fixed, and after ensuring that the upper planes of the four supporting angle pieces 3 remain in the same plane, the partition plate 8 is fixed on the supporting angle piece 3, and then the lithium battery 2, the circuit controller 9 and the power board 10 are fixed on the surface of the partition plate 8 in sequence. The above arrangement method utilizes the partition plate 8 The internal space of the bicycle battery placement box 1 is divided into two upper and lower areas, and the fuel cell system 6 and the lithium battery 2 energy system and the control circuit board can be separated and arranged in two relatively independent spaces, which is convenient for the separate management of the fuel cell and the lithium battery 2.
