[0002] Hydrogen fuel cells are a type of power generation device that utilizes hydrogen energy through chemical reactions. During operation, only water is generated, achieving true zero emissions. Compared with traditional methods of burning fuels, hydrogen fuel cells have higher energy conversion efficiency and lower emissions, becoming one of the important technologies for future environmentally friendly energy.

[0003] The basic principle is the reverse reaction of water electrolysis, supplying hydrogen and oxygen to the anode and cathode respectively, and hydrogen diffuses outward through the anode and the electrolyte.

[0004] Existing hydrogen fuel cells are configured in a square shape and are fixed to the vehicle body with bolts. However, when installing hydrogen fuel cells on some large trucks, they are installed on the vehicle chassis. Since there are multiple support beams on the vehicle chassis, the space for fixing the hydrogen fuel cell is limited, resulting in the bottom of the hydrogen fuel cell being unable to be placed flat. The fixing method is limited and there is no protective function. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 In an embodiment of the utility model, a hydrogen fuel cell with a safety protection structure includes a battery 1, two bottom support beams 10 are welded at the bottom of the battery 1, and two clips 11 are clamped at the bottom of each bottom support beam 10 and fixedly connected by bolts; a rubber protection plate 13 is bonded to the bottom of the two clips 11; the clips 11 are C-shaped and are externally connected with a locking bolt 12;

[0024] A cross bracket 14 arranged in an "X" shape is also fixed to the bottom of the battery 1, and pressure sensors 15 are fixed to the four outer ends of the cross bracket 14; multiple pressure sensors 15 are electrically connected to the control board; the control board is embedded in the hollow part in the middle position of the cross bracket 14, and a buzzer 16 is provided on the outside of the control board; the buzzer 16 is electrically connected to the control board.

[0025] By adopting the above technical solution, the four pressure sensors 15 can monitor the buckling force of the four buckles 11. When one of the buckles 11 becomes loose or deflected, the verticality of the corresponding pressure sensor 15 will change to a certain extent; the monitoring values ​​of the four pressure sensors 15 will be transmitted to the control board, and the pressure of the four pressure sensors will be analyzed by the control board; when the pressure is uneven, an alarm will be sounded through the buzzer 16 to alert the staff, so that the staff can adjust the battery status in time, which effectively plays the role of early warning and advance protection.

[0026] In this embodiment, the battery 1 includes a battery housing 101, and a hydrogen chamber 102 and an oxygen chamber 106 are provided inside the battery housing 101; the hydrogen chamber 102 and the oxygen chamber 106 are separated by a positive electrode sheet 103 and a negative electrode sheet 105; and an electrolyte storage chamber 104 is between the positive electrode sheet 103 and the negative electrode sheet 105.

[0027] In this embodiment, a catalyst layer is provided at the lower end of the positive electrode sheet 103 and the negative electrode sheet 105 .

[0028] In this embodiment, a battery cover 9 is fixed to the top of the battery housing 101 by bolts; and protective ribs 2 are integrally provided around the battery housing 101 .

[0029] In this embodiment, one end of the battery housing 101 is provided with an air inlet connector 3, a hydrogen fuel injection port 4, a positive power column 5, a negative power column 6, a drain port 7 and a power plug 8, wherein the positive power column 5 is connected to the positive electrode sheet 103, and the negative power column 6 is connected to the negative electrode sheet 105; the drain port 7 is connected to the oxygen chamber 106; and the hydrogen fuel injection port 4 is connected to the hydrogen chamber 102.

[0030] The catalyst layer at the lower end of the positive electrode sheet 103 and the negative electrode sheet 105 is pre-buried with an electrode wire, and the two electrode wires are electrically connected to the power plug 8; the power plug 8 is used to supply electricity for the truck.

[0031] The working principle of the utility model is: when installing, first fix a plurality of snap fasteners 11 on the two bottom support beams 10, then use bolts to lock and fix, then bond and fix the rubber protective plate 13 to the snap fasteners 11, then fix the snap fasteners 11 to the crossbeam of the truck, and then use the locking bolts 12 to lock; thereby, the battery and the truck are fixed, and this fixing method can be perfectly connected to the truck, and does not require the bottom of the battery 1 to be completely placed on the truck, the bottom contact requirement is not high, and the installation is relatively convenient;

[0032] When in use, hydrogen is sent to the negative electrode sheet 105 of the fuel cell through the hydrogen fuel injection port 4. After the action of the catalyst (platinum), one electron in the hydrogen atom is separated, and the hydrogen ion (proton) that has lost the electron passes through the proton exchange membrane and reaches the positive electrode sheet 103 of the fuel cell. However, the electron cannot pass through the proton exchange membrane. This electron can only reach the positive electrode sheet 103 of the fuel cell through the external circuit, thereby generating current in the external circuit. After the electron reaches the positive electrode sheet 103, it recombines with the oxygen atom and the hydrogen ion to form water. Since the oxygen supplied to the positive electrode sheet 103 can be obtained from the air, as long as hydrogen is continuously supplied to the negative electrode sheet 105, air is supplied to the positive electrode sheet 103, and water (steam) is taken away in time, electric energy can be continuously provided. The electricity generated by the fuel cell is supplied to the motor through the inverter, controller and other devices, and then the wheels are driven to rotate through the transmission system, drive axle, etc., so that the vehicle can be driven on the road.

[0033] The four pressure sensors 15 can monitor the snapping force of the four snapping parts 11. When one of the snapping parts 11 becomes loose or deflected, the verticality of the corresponding pressure sensor 15 will change to a certain extent. The monitoring values ​​of the four pressure sensors 15 will be transmitted to the control board, and the pressure of the four pressure sensors will be analyzed by the control board. When the pressure is uneven, an alarm will be sounded through the buzzer 16 to alert the staff, so that the staff can adjust the battery status in time, which effectively plays the role of early warning and advance protection.
