The hydrogen fuel cell stack, power inverter, and starting battery are fixedly mounted on the bottom surface of the enclosure. The hydrogen fuel cell stack is located on the right side inside the enclosure, and the power inverter is located on the left side of the front of the hydrogen fuel cell stack. The power inverter converts the direct current generated by the hydrogen fuel cell stack through the direct conversion of the chemical energy of hydrogen and oxygen into alternating current. The starting battery is located on the left side of the rear of the hydrogen fuel cell stack; the starting battery is electrically connected to the hydrogen fuel cell stack and the power inverter. The hydrogen cylinder is fixed to the upper part of the hydrogen fuel cell stack, and the rear end of the hydrogen cylinder corresponds to the position of the mounting through hole opened on the rear side of the housing. The suction connector is fixed to the upper part of the front side. The suction connector includes a snap-fit ​​nut and a valve. The front end of the hydrogen cylinder is snapped into the snap-fit ​​nut. When the hydrogen cylinder is snapped into the snap-fit ​​nut and the valve is open, the hydrogen cylinder is in a venting state.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4As shown, a portable hydrogen generator includes a housing 1, a hydrogen fuel cell stack 2, a power inverter 7, a starting battery 9, a hydrogen cylinder 3, an intake connector 5, a hydrogen pipe 4, a controller 8, a switch panel 12, a hydrogen valve switch 10, a radiator 6, a retaining ring 11, a handle 13, and a soft, adjustable rubber pad 14. The housing 1 includes a front side 101, a rear side 102, a left side 103, a right side 104, a top surface 105, and a bottom surface 106. The upper part of the rear side 102 is provided with a mounting through hole 31 through which the hydrogen cylinder can pass. The hydrogen fuel cell stack 2, the power inverter 7, the starting battery 9, and the hydrogen cylinder 3 are all located inside the housing 1. The hydrogen fuel cell stack 2, the power inverter 7, and the starting battery 9 are all located inside the housing 1. The hydrogen fuel cell stack 2 is fixedly installed on the bottom surface 106 of the housing 1. It is located inside the housing 1 on the right side. The power inverter 7 is located on the left side of the front of the hydrogen fuel cell stack 2. The power inverter 7 converts the direct current generated by the direct conversion of the chemical energy of hydrogen and oxygen in the hydrogen fuel cell stack 2 into alternating current. The starting battery 9 is located on the left side of the rear of the hydrogen fuel cell stack 2. The starting battery 9 is electrically connected to the hydrogen fuel cell stack 2 and the power inverter 7. The fixing ring 11 is annular and located on the upper part of the hydrogen fuel cell stack 2. The hydrogen cylinder 3 is cylindrical, and the fixing ring 11 securely engages the hydrogen cylinder 3. The rear end of the hydrogen cylinder 3 is connected to the... The mounting through hole 31 on the rear side of the housing corresponds to the position of the housing. The intake connector 5 is fixed to the upper part of the front side. The intake connector 5 includes a snap-fit ​​nut 51 and a valve 52. The front end of the hydrogen cylinder 3 is snapped into the snap-fit ​​nut 51. When the hydrogen cylinder 3 is snapped into the snap-fit ​​nut 51 and the valve 52 is open, the hydrogen cylinder 3 is in a venting state. Of course, when the valve 52 is closed, the hydrogen cylinder 3 is in a sealed state. The upper end of the hydrogen pipe 4 is connected to the snap-fit ​​nut 51, and the lower end of the hydrogen pipe 4 is connected to the hydrogen fuel cell stack 2. It can input the hydrogen in the hydrogen cylinder 3 into the hydrogen fuel cell stack 2 to directly convert the chemical energy of hydrogen and oxygen and output electricity. The controller 8 is located above the power inverter 7 and controls the operation of the power inverter 7. The switch panel 12 is located on the left side 103 of the enclosure 1 and includes a socket 107 and a controller button 121. The position of the controller button 121 corresponds to the position of the controller 8 and controls the start and stop of the controller 8. The socket 107 outputs the power generated after inversion by the power inverter 7. The hydrogen valve switch 10 is located on the upper part of the rear side, above the mounting through hole 31, and controls the opening of the valve 52. The heat sink 6 is located inside the enclosure 1 and dissipates the heat inside the enclosure 1 to the outside.A heat dissipation hole 16 is also provided on the right side 104 of the housing 1. The radiator 6 is located on the right side inside the housing 1, and the heat dissipation hole 16 corresponds to the position of the radiator 6. A handle 13 is provided on the top surface 105 of the housing 1, forming a space between the handle 13 and the top surface 105 for easy gripping. The front end of the handle 13 is fixedly connected to the front end of the housing 1, and the rear end of the handle 13 is fixedly connected to the rear end of the housing 1. Oval holes 15 for heat dissipation are provided on the sides of the housing 1. Adjustable soft rubber pads 14 are distributed at the bottom of the housing, and are positioned at the same height. This helps to adjust the stability of the generator and reduces vibration and noise.

[0023] The portable hydrogen generator using this technical solution first ensures that there is enough hydrogen in the hydrogen cylinder 3. Then, the hydrogen valve switch 10 and the controller button 121 are opened in sequence. The hydrogen valve switch 10 opens the valve 52, and the hydrogen in the hydrogen cylinder 3 is input into the hydrogen fuel cell stack 2 through the hydrogen pipe 4. The hydrogen fuel cell stack 2 directly converts the chemical energy of hydrogen and oxygen into DC electrical energy. The controller button 121 controls the power inverter 7 to operate, converting the DC power through the power inverter 7 into AC power, which is finally connected to the socket. The user can directly draw power from the socket 107.

[0024] This technical solution features a simple structure. Since the hydrogen cylinder 3 is positioned above the hydrogen fuel cell stack 2, the weight difference between the hydrogen fuel cell stack 2, the power inverter 7, the starting battery 9, and the hydrogen cylinder 3 ensures the entire hydrogen generator is top-light and bottom-heavy, with a low center of gravity. Furthermore, because the hydrogen generator uses hydrogen cylinders for power, it is lightweight and easy to carry. A soft, adjustable rubber pad 14 at the bottom of the housing 1 ensures the generator's stability. The rational layout of the hydrogen fuel cell stack 2, power inverter 7, starting battery 9, and hydrogen cylinder 3 results in a smaller overall footprint and a more compact design, further improving portability. The presence of a heat sink 6 inside the hydrogen fuel cell stack 2 and waist-shaped holes 15 and ventilation holes 16 on the housing 1 prevents overheating due to the compact layout. Additionally, a dedicated built-in handle 13 facilitates carrying.

[0025] When the hydrogen cylinder 3 is empty under normal circumstances, it can be directly replaced with hydrogen tank 3. When it is inconvenient to carry a spare hydrogen cylinder 3 or when the spare hydrogen cylinder 3 is used up, it can also be replenished by using a cartridge gas canister to align with the intake connector 5, which greatly improves flexibility. This utility model provides a brand-new layout structure, which fully reflects the advantages of hydrogen generator.
