[0001] The invention relates to the technical field of electrolytic cells for electrolyzing water to produce hydrogen, in particular to an electrolytic cell for electrolyzing water to produce hydrogen. Background Art

[0002] Hydrogen energy is a clean, efficient and sustainable secondary energy source that can be used in industries, transportation, power generation and energy storage. Therefore, hydrogen production technology is particularly important. In the process of producing hydrogen through water electrolysis, the electrolyzer is the key equipment for producing hydrogen. By applying direct current, water molecules are decomposed into hydrogen and oxygen, thus producing hydrogen effectively.

[0003] For example, the patent disclosed in the prior art with the publication number "CN117107267A" is named "A filter press type electrolyzer and control method for supercapacitor decoupling electrolysis of water to produce hydrogen", which discloses a circumferential pole frame that penetrates the end plate, supercapacitor pole plate and conductive flow channel plate along the axial direction of the cylinder, and penetrates the sealing gasket to respectively set the electrolyte liquid inlet channel, hydrogen side gas-liquid discharge channel and oxygen side gas-liquid discharge channel, each channel and the external pipeline of the electrolyzer, gas-liquid separation tank, pump and flow meter constitute an electrolyte circulation system, the hydrogen production chamber of each electrolysis chamber is connected to the hydrogen side gas-liquid discharge channel, and the oxygen production chamber of each electrolysis chamber is connected to the oxygen side gas-liquid discharge channel. For example, the prior art publication number "CN216 The patent name disclosed in "738564U" is "A New Electrolyzer for Hydrogen Production by Alkaline Water Electrolysis". It discloses that a drive motor is started by a drive motor switch, the drive motor drives a first helical gear to rotate, the first helical gear drives a second helical gear to rotate, the second helical gear drives a transmission rod to rotate, the transmission rod rotates a connecting pipe, and the connecting pipe rotates a stirring blade. The two connecting pipes are respectively placed on one side of the anode and one side of the cathode. When the stirring blade rotates, it stirs the alkaline electrolyte, and the alkaline electrolyte flushes the surface of the anode and the surface of the cathode, causing bubbles attached to the anode and the cathode to overflow, thereby increasing the working surface area of ​​the anode and the cathode, and improving the efficiency of hydrogen production by alkaline water electrolysis.

[0004] When the electrolytic cell in the above-mentioned prior art is in use, although the alkaline electrolyte is stirred by the stirring blade to cause the bubbles attached to the anode and cathode to overflow, the position of the stirring blade is fixed, so that the stirring range of the stirring blade is fixed, which makes the stirring effect poor, resulting in some bubbles being retained on the cathode and anode, thereby affecting the electrolysis efficiency of the electrolytic cell and thus affecting the hydrogen production efficiency.

[0033] The inner side of the first end plate 1 is rotatably mounted with a ring gear 7 and a transmission gear 6, and the transmission gear 6 is meshed with the ring gear 7, and a convex plate 71 is fixed to one side of the ring gear 7, and a row of protrusions 72 are installed on the inner side of the protrusion 71, and the protrusions 72 are arranged in an arc shape. The outer side of the ring gear 7 is provided with a bolt 3, and the rotation angle of the ring gear 7 is less than 180 degrees. The first push column 18 forms a sliding structure through the protrusion 72, and a horizontal plate 23 is installed on one side of the horizontally arranged stirring block 22, and stirring plates are fixed on the upper and lower sides of the horizontal plate 23. 24. A second fixed tube 20 is fixed in both the first cylinder frame 8 and the second cylinder frame 11, and a second sealing piston 211 is fittedly connected to the interior of the second fixed tube 20. One side of the second sealing piston 211 is connected to the second push column 21. A second push column 21 is fixed above the side of the horizontal plate 23 away from the stirring block 22. A liquid inlet pipe 25 is fixed through the left side of one end of the second fixed tube 20, and a spraying pipe 26 is fixed through the right side of one end of the second fixed tube 20. One-way valves are installed inside the liquid inlet pipe 25 and the spraying pipe 26.

[0034] Firstly, the electrolyte is injected into the electrolytic tank body 4 through the electrolyte inlet 2, and flows into the first cylinder frame 8 and the second cylinder frame 11 through the electrolyte passage holes in the cathode plate 9, the anode plate 12 and the diaphragm body 17. Then, the cathode terminal 91 and the anode terminal 121 are connected to the power supply outside, so that the cathode plate 9 and the anode plate 12 are connected to the direct current. Then, hydrogen is generated at the cathode plate 9 and is discharged through the hydrogen discharge port 81 and the hydrogen discharge pipe 5. Oxygen is generated at the anode plate 12 and is discharged through the oxygen discharge port 111 and the oxygen discharge pipe 13. Since this part is prior art, it will not be described in detail here.

[0035] During the electrolysis process, the left end of the transmission gear 6 is connected to the servo motor outside, and the servo motor drives the transmission gear 6 to rotate clockwise and counterclockwise reciprocatingly. The transmission gear 6 drives the gear ring 7 to rotate clockwise and counterclockwise reciprocatingly by less than 180°, as shown in the accompanying drawings. When the gear ring 7 rotates counterclockwise, the gear ring 7 drives the outer convex plate 71 and the convex block 72 to rotate. When the convex block 72 rotates to contact the first push column 18 at the corresponding position, the arc-shaped convex block 72 applies an inward pushing force to the first push column 18 at the corresponding position. Thus, the plurality of first push columns 18 drive the stirring block 22 and the first sealing piston 181 to move into the first cylinder frame 8 and the second cylinder frame 11, respectively. At the same time, one end of the horizontally arranged stirring block 22 drives the transverse plate 23 and the stirring plate 24 to move inward together. Therefore, the arc-shaped stirring block 22 and the wave-shaped stirring plate 24 reciprocate to stir the electrolyte in the first cylinder frame 8 and the second cylinder frame 11, thereby improving the stirring efficiency and increasing the stirring range, avoiding the retention of bubbles on the cathode plate 9 and the anode plate 12, and thus improving the electrolysis efficiency of the electrolytic tank body 4. Figure 2 When the transverse plate 23 moves inward, the second push column 21 and the second sealing piston 211 move inward. At this time, the peripheral part of the electrolyte enters the second fixed pipe 20 through the liquid inlet pipe 25 with a one-way valve installed inside. When the transverse plate 23 moves outward to reset, the second push column 21 and the second sealing piston 211 move inward, and the electrolyte in the second fixed pipe 20 is sprayed to one side of the cathode plate 9 and the anode plate 12 through the spraying pipe 26. Thus, the bubbles retained on the cathode plate 9 and the anode plate 12 can be further removed, the effective reaction area of the cathode plate 9 and the anode plate 12 is increased, and thus the electrolysis efficiency of the electrolytic tank body 4 can be further improved, and the hydrogen production efficiency can be further improved.

[0036]

[0037] ​Example 2: The electrolytic cell for hydrogen production by electrolysis of water in this embodiment is based on Example 1, which not only facilitates the stacking assembly of the first cylinder frame 8, the second cylinder frame 11, the cathode plate 9, the anode plate 12 and the diaphragm body 17 in a guided and limited manner, but also facilitates the replacement of the first cylinder frame 8, the second cylinder frame 11, the cathode plate 9, the anode plate 12 or the diaphragm body 17 without being placed in a disorderly manner. For the specific structure, refer to the attached Figure 6 and Figure 9 As shown, a rectangular guide plate 15 is fixed to the left side of the second end plate 16, and a connecting block 142 is fixed above the first cylinder frame 8, the cathode plate 9, the anode plate 12, the second cylinder frame 11 and the diaphragm body 17. The top of the connecting block 142 is connected to the guide block 14 by a fixing screw 141, and the guide plate 15 is provided through the inside of the guide block 14.

[0038] When it is necessary to replace the first cylinder frame 8, the second cylinder frame 11, the cathode plate 9, the anode plate 12 or the diaphragm body 17, first use a tool to separate the bolt 3 from the second end plate 16, then separate the oxygen exhaust pipe 13 from the multiple oxygen exhaust ports 111, and separate the hydrogen exhaust pipe 5 from the multiple hydrogen exhaust ports 81. At this time, the multiple first cylinder frames 8, the second cylinder frames 11, the cathode plate 9, the anode plate 12 and the diaphragm body 17 are suspended on the outside of the rectangular guide plate 15 through the guide block 14, and then find one of the first cylinder frames 8. Frame 8, second cylinder frame 11, cathode plate 9, anode plate 12 or diaphragm body 17, remove the corresponding fixing screws 141 to separate the connecting block 142 from the guide block 14, so that one of the first cylinder frames 8, second cylinder frames 11, cathode plate 9, anode plate 12 or diaphragm body 17 can be disassembled and replaced, and at the same time, multiple first cylinder frames 8, second cylinder frames 11, cathode plate 9, anode plate 12 and diaphragm body 17 are not placed randomly, and do not need to be sorted later, thereby improving the efficiency of later stacking and assembly.

[0039] Example 3: The electrolytic cell for electrolysis of water to produce hydrogen in this embodiment can further improve the efficiency of cooling or heating the electrolytic cell body 4 on the basis of Example 1. For the specific structure, refer to the attached Figure 8 As shown, the interiors of the first push column 18 and the stirring block 22 are both hollow, and the interiors of the first push column 18 and the stirring block 22 are communicated with each other.

[0040] The temperature is detected by a temperature sensor installed on the electrolytic cell body 4. When the temperature inside the electrolytic cell body 4 is low, a certain amount of hot water is injected into the first hollow push column 18 and the stirring block 22. Similarly, when the temperature inside the electrolytic cell body 4 is high, a certain amount of cold water is injected into the first hollow push column 18 and the stirring block 22. The coordinated use of the reciprocating first push column 18 and the stirring block 22 facilitates the auxiliary regulation of the temperature inside the electrolytic cell body 4, so that the electrolytic cell body 4 is used at an appropriate temperature, thereby controlling the viscosity of the electrolyte, accelerating the movement speed of ions, and improving the conductivity of the electrolyte. At the same time, by controlling the temperature of the electrolytic cell body 4, the electrochemical reaction activity can be reduced, the rate of the oxidation reaction can be reduced, and the hydrogen yield can be increased, thereby further improving the electrolysis efficiency, improving the performance and life of the electrolytic cell body 4, and completing a series of tasks.
