[0002] At present, the main methods for producing hydrogen include: hydrogen production from fossil energy, industrial by-product hydrogen, water electrolysis, bioenergy fermentation, thermochemical method and solar energy hydrogen production. Among them, large-scale application methods include hydrogen production from fossil energy and industrial by-product hydrogen, which currently account for 97%, and alkaline water electrolysis is also in the small-scale practical stage, accounting for about 3%, while other methods have not yet been applied on a large scale.
[0003] Photovoltaic electrolysis of water to produce hydrogen is to convert solar energy into electrical energy through photovoltaic cells, and then convert the electrical energy into hydrogen energy through water electrolysis. Photoelectrode hydrogen production can directly convert solar energy into hydrogen energy in one step, which significantly improves both cost and efficiency.
[0004] In order to separate the generated oxygen and hydrogen, photoelectrode hydrogen production has gradually developed into photoelectrochemical water decomposition. The photocatalyst is made into an electrode. The catalyst electrode and the counter electrode are placed in two chambers respectively. The catalyst electrode and the counter electrode are connected by a wire, and a bias voltage is usually added. If the semiconductor material is n-type, oxygen is generated at the catalyst electrode and hydrogen is generated at the counter electrode; if the semiconductor material is p-type, the opposite is true.
[0005] During the entire hydrogen production process, acidic solution or alkaline solution needs to be continuously added to keep the pH value in the chamber within the optimal range of the photocatalytic reaction. However, after adding acidic solution or alkaline solution, the acidic solution or alkaline solution diffuses unevenly in the water and the diffusion time is long, resulting in the defect of uneven solution pH value.

[0031] The following is combined with Figure 1-8 This application is described in further detail.
[0032] The embodiment of the present application discloses a solar water decomposition hydrogen production system.
[0033] refer to Figure 1As shown in the figure, a solar water decomposition hydrogen production system includes a decomposition station 1, wherein two decomposition chambers 11 are provided in the decomposition station 1, and two liquid replenishment tanks 8 are arranged above each decomposition chamber 11. The liquid replenishment tanks 8 are hollow structures, and one of the liquid replenishment tanks 8 above each decomposition chamber 11 is used to hold an acidic solution, and the other liquid replenishment tank 8 above each decomposition chamber 11 is used to hold an alkaline solution. The bottom of the liquid replenishment tank 8 extends into the decomposition chamber 11, and the outer wall of the liquid replenishment tank 8 is fixed to the decomposition station 1.
[0034] In order to ensure that the pH value in the decomposition chamber 11 is within the optimal range of the photocatalytic reaction, it is necessary to add an acidic solution or an alkaline solution to the decomposition chamber 11 through the liquid replenishment tank 8. After the addition is completed, the solution in the decomposition chamber 11 is fully stirred to improve the uniformity of the pH value in the decomposition chamber 11 and reduce the diffusion time of the added acidic solution or alkaline solution.
[0035] refer to Figure 3 A closing plate 81 is provided in the fluid replenishing tank 8. Two closing plates 81 are provided. The two closing plates 81 are arranged opposite to each other. The opposite sides of the two closing plates 81 are rotatably connected to the inner wall of the fluid replenishing tank 8. A torsion spring 811 is installed at the rotation connection between the closing plate 81 and the fluid replenishing tank 8.
[0036] refer to Figure 3 , the two closing plates 81 are hinged on one side relative to each other with a liquid baffle plate 82, and a sealing sheet is fixedly arranged at the hinge between the liquid baffle plate 82 and the closing plate 81, and the sealing sheet is made of a flexible material and is used to seal the hinge between the closing plate 81 and the liquid baffle plate 82, and the sealing sheet is not shown in the figure, and a slider 821 is hinged on the side of the liquid baffle plate 82 away from the closing plate 81, and a sealing sheet is also fixedly arranged at the hinge between the liquid baffle plate 82 and the slider 821, and a slide groove 83 is provided on the inner wall of the liquid infusion tank 8 for slidingly matching with the slider 821, and the slide groove 83 is provided in the vertical direction, and an auxiliary spring 84 is arranged in the slide groove 83, and one end of the auxiliary spring 84 is fixed to the slider 821, and the other end of the auxiliary spring 84 is fixed to the liquid infusion tank 8.
[0037] When the closing plate 81 is squeezed, the two closing plates 81 move away from each other. At this time, the torsion spring 811 is in a stretched state, thereby connecting the fluid replenishing tank 8 with the decomposition chamber 11, so that the acidic solution or alkaline solution in the fluid replenishing tank 8 flows into the decomposition chamber 11; at this time, the closing plate 81 drives the slider 821 to slide in the slide groove 83 through the liquid baffle plate 82, and the auxiliary spring 84 is in a compressed state.
[0038] When the closing plate 81 is not squeezed, the torsion spring 811 releases its elastic force to drive the two closing plates 81 closer to each other. At the same time, the auxiliary spring 84 releases its elastic force to drive the liquid baffle plate 82 to reset via the slider 821, thereby separating the liquid infusion tank 8 from the decomposition chamber 11. The acidic solution or alkaline solution in the liquid infusion tank 8 is temporarily stored in the liquid infusion tank 8.
[0039] refer to Figure 3 A one-way valve 10 is installed at the bottom of the liquid replenishment tank 8, and the acidic solution or alkaline solution in the liquid replenishment tank 8 can only flow into the decomposition chamber 11 in one direction, preventing the gas generated in the decomposition chamber 11 from entering the liquid replenishment tank 8.
[0040] refer to Figure 3 and Figure 4 An opening and closing assembly 9 is provided in the infusion tank 8, and the opening and closing assembly 9 includes a support rod 91 and a trigger rod 92. The support rod 91 is fixedly arranged in the infusion tank 8 along the horizontal direction, and the support rod 91 is arranged on the top of the infusion tank 8. A driving motor 911 is fixedly installed on the support rod 91. A driving gear 9111 is fixedly arranged on the output shaft of the driving motor 911. The driving gear 9111 uses an incomplete gear. The trigger rod 92 passes through the support rod 91 and the two are slidably adapted. The bottom end of the trigger rod 92 is used to squeeze the two closing plates 81, and one side of the trigger rod 92 is fixedly provided with a driving rack 921 meshing with the driving gear 9111.

A reset spring 923 is fixedly provided between the reset plate 922 and the support rod 91 , and the reset spring 923 is sleeved on the trigger rod 92 .
[0042] After the driving motor 911 is started, the driving motor 911 drives the driving gear 9111 to rotate; when the driving gear 9111 is engaged with the driving rack 921, the driving gear 9111 drives the trigger rod 92 to squeeze the closing plate 81 through the driving rack 921, so that the acidic solution or alkaline solution in the fluid infusion tank 8 flows into the decomposition chamber 11, and at the same time, the driving rack 921 stretches the reset spring 923 through the reset plate 922; when the driving gear 9111 is not engaged with the driving rack 921, the reset spring 923 releases its elastic force to drive the trigger rod 92 away from the closing plate 81 through the reset plate 922.
[0043] refer to Figure 2 , Figure 4 and Figure 5 A pH value detection sensor is installed in the decomposition chamber 11. The pH value detection sensor is used to detect the pH value in the decomposition chamber 11 and output a pH value signal. The output end of the pH value detection sensor is connected to a comparator. The comparator is used to receive the pH value signal and compare the reference value with the pH value signal. The reference value is the optimal pH value range of the photocatalyst reaction. After comparison, the comparator outputs an execution signal. The execution signal includes a start signal and a stop signal. The output end of the comparator is connected to the drive motor 911.
[0044] When the pH value detected by the pH value detection sensor is lower than the reference value, the comparator transmits a start signal to the drive motor 911 on the fluid replenishment tank 8 containing the alkaline solution. At this time, the alkaline solution in the fluid replenishment tank 8 flows into the decomposition chamber 11, thereby increasing the pH value in the decomposition chamber 11; when the pH value detected by the pH value detection sensor is within the reference value range, the comparator transmits a stop signal to the drive motor 911 on the fluid replenishment tank 8 containing the alkaline solution.
[0045] When the pH value detected by the pH value detection sensor is higher than the reference value, the comparator transmits a start signal to the drive motor 911 on the fluid replenishment tank 8 containing the acidic solution. At this time, the acidic solution in the fluid replenishment tank 8 flows into the decomposition chamber 11, thereby reducing the pH value in the decomposition chamber 11; when the pH value detected by the pH value detection sensor is within the reference value range, the comparator transmits a stop signal to the drive motor 911 on the fluid replenishment tank 8 containing the acidic solution.
