[0001] The embodiments in this application relate to the field of new energy equipment technology, and in particular to an electrolysis component and an electrolysis hydrogen production device. Background Technology

[0002] In related technologies, electrolytic cells and other electrolytic components can usually have gaskets placed between the electrode frames. The gaskets play a sealing role in the electrolytic component, which can prevent electrolyte leakage and also play a role in pressure distribution to the electrodes or diaphragms, ensuring the stable operation of the electrolytic component.

[0003] However, current gaskets cannot be reused well after assembly, and they are prone to shear breakage, which reduces the practicality and reliability of electrolysis components. Utility Model Content

[0004] Several embodiments in this application propose an electrolysis assembly and an electrolysis hydrogen production device, aiming to improve the structural design of the electrode frame and gasket, and enhance the practicality and reliability of the electrolysis assembly.

[0005] An embodiment of this application provides an electrolysis assembly including an electrode frame and a gasket. The electrode frame includes a first frame and a second frame, which are stacked. The surface of the first frame facing the second frame and the surface of the second frame facing the first frame are provided with a limiting groove. The gasket is disposed between the first frame and the second frame. The surface of the gasket facing the first frame and the surface of the gasket facing the second frame are provided with a protrusion, which engages with the limiting groove.

[0006] In one embodiment, the gasket includes a first sealing portion and a second sealing portion, the second sealing portion being sleeved on the outer periphery of the first sealing portion, and the protrusion being provided on the surface of the second sealing portion.

[0007] In one embodiment, at least one of the surfaces of the first sealing portion facing the first frame and the first sealing portion facing the second frame is provided with a rib.

[0008] In one embodiment, the first sealing part includes a first ring and a first cover, the first cover being disposed around the first ring; the first ring is made of an elastic gel material, and the first cover is made of a corrosion-resistant material.

[0009] In one embodiment, the second sealing part includes a second ring and a second cover, the second cover being disposed around the second ring; the second ring is made of an elastic colloid material, and the second cover is made of a corrosion-resistant material.

[0010] In one embodiment, the second ring body includes at least two single rings, which are sequentially and spaced apart.

[0011] In one embodiment, the first sealing part and the second sealing part are an integral structure.

[0012] In one embodiment, the width of the limiting groove gradually decreases along the direction away from the washer.

[0014] An embodiment of this application also proposes an electrolytic hydrogen production device, which includes a device body and an electrolysis component, wherein the electrolysis component is the aforementioned electrolysis component, and the electrolysis component is installed on the device body.

[0015] In the various embodiments provided in this application, at least one of the first frame and the second frame is provided with a limiting groove, and at least one of the two opposing surfaces of the gasket is provided with a protrusion.

[0031] In related technologies, electrolytic cells and other electrolytic components typically use gaskets between the electrode frames. These gaskets act as seals, preventing electrolyte leakage and distributing pressure across the electrodes or diaphragm, thus ensuring stable operation. However, current gaskets are not easily reusable after assembly and are prone to shear breakage, reducing their practicality and reliability.

[0032] It is understandable that an electrolysis assembly typically includes a first frame, a second frame, electrodes, a diaphragm, and gaskets. By stacking positive and negative electrodes on the opposing surfaces of the first and second frames, and placing a diaphragm on either the positive or negative electrode, a gasket can be positioned between the first and second frames. This allows the first and second frames to be pre-tightly stacked and assembled to form the electrolysis chamber of the electrolytic cell. The gaskets prevent electrolyte leakage from the electrolysis chamber and separate the positive and negative electrodes, preventing the gases generated by the positive and negative electrodes from mixing and interfering. Most gaskets in electrolysis assemblies are flat gaskets. However, sealing water lines such as teeth or ribs can be provided on the surface of the electrode frame to press against the gasket surface. This increases the contact force between the sealing water lines and the gasket, preventing the gasket from detaching from the electrode frame and achieving a more stable and reliable sealing effect. However, using a sealing water line to press the gasket creates a deep indentation on the gasket surface and easily causes shear fracture due to the pressure of the sealing water line, affecting the overall structural stability of the gasket and making it unusable. To address these problems, this application proposes an electrolysis assembly 100.

[0033] Please see Figures 2 to 5In one embodiment of this application, the electrolysis assembly 100 includes an electrode frame 10 and a gasket 30. The electrode frame 10 includes a first frame 11 and a second frame 13, which are stacked. The surface of the first frame 11 facing the second frame 13 and the surface of the second frame 13 facing the first frame 11 are provided with a limiting groove 15. The gasket 30 is disposed between the first frame 11 and the second frame 13. The surface of the gasket 30 facing the first frame 11 and the surface of the gasket 30 facing the second frame 13 are provided with a protrusion 335, which engages with the limiting groove 15.

[0034] In this application, by providing mutually cooperating limiting grooves 15 and protrusions 335 on the relative contact surfaces of the electrode frame 10 and the gasket 30, and utilizing the engagement of the protrusions 335 and the limiting grooves 15, a stable limiting assembly of the gasket 30 between the first frame 11 and the second frame 13 can be achieved, preventing the gasket 30 from shifting on the electrode frame 10 and effectively preventing the gasket 30 from detaching from the electrode frame 10. Furthermore, the mutually cooperating limiting grooves 15 and protrusions 335 enable a structural fit between the electrode frame 10 and the gasket 30, reducing indentations caused by the electrode frame 10 pressing on the gasket 30, lowering the shear stress on the gasket 30, preventing deformation or breakage of the gasket 30, ensuring the sealing effect of the gasket 30 in the electrolysis assembly 100, and allowing for better reuse of the gasket 30.

[0035] In one configuration, the pole frame 10 can have a limiting groove 15 on the surface of the first frame 11 facing the second frame 13. In this configuration, the washer 30 can have a corresponding protrusion 335 on the surface of the first frame 11, allowing the washer 30 to engage with the first frame 11 for a secure fit. Alternatively, the pole frame 10 can have a limiting groove 15 on the surface of the second frame 13 facing the first frame 11. In this configuration, the washer 30 can have a corresponding protrusion 335 on the surface of the second frame 13, allowing the washer 30 to engage with the first frame 11 for a secure fit. The snap-fit ​​connection achieves a stable assembly between the washer 30 and the pole frame 10; alternatively, the pole frame 10 may have limiting slots 15 on both the surface of the first frame 11 facing the second frame 13 and the surface of the second frame 13 facing the first frame 11, and protrusions 335 on both the surface of the washer 30 facing the first frame 11 and the surface of the washer 30 facing the second frame 13, so that the washer 30 can be engaged with the first frame 11 and the second frame 13 respectively by using the protrusions 335 on the two opposing surfaces, thereby achieving a more stable assembly between the pole frame 10 and the washer 30.

[0036] The limiting slot 15 can be designed as a square slot, a circular slot, a triangular slot, etc., and the protrusion 335 can be designed as a square protrusion, a semi-circular protrusion, a triangular protrusion, etc. The number of limiting slots 15 can be set to one, two, three, four, five, etc., and the number of protrusions 335 can correspond to the number of limiting slots 15. When more than two limiting slots 15 are used, multiple limiting slots 15 can be arranged sequentially and alternately. At this time, multiple protrusions 335 corresponding to the number of limiting slots 15 can be simultaneously and sequentially arranged and alternately placed on the surface of the washer 30, so that multiple limiting slots 15 and multiple protrusions 335 can be engaged one-to-one, achieving a more stable and reliable assembly effect between the washer 30 and the pole frame 10. This application does not limit the shape and number of limiting slots 15 and protrusions 335, as long as the corresponding engagement of the limiting slots 15 and protrusions 335 can be achieved.

[0037] In one embodiment of this application, a limiting groove 15 is provided on at least one of the first frame 11 and the second frame 13, and a protrusion 335 is provided on at least one of the two opposing surfaces of the gasket 30. The limiting groove 15 and the protrusion 335 are engaged and locked together. The engagement and positioning of the protrusion 335 and the limiting groove 15 can be used to achieve the positioning and assembly of the gasket 30 in the electrode frame 10, preventing the gasket 30 from shifting during assembly and achieving a better sealing effect of the gasket 30 in the electrolysis assembly 100. Furthermore, by pre-setting the engaging structure on the electrode frame 10 and the gasket 30 respectively, the indentation left by the electrode frame 10 pressing on the surface of the gasket 30 can be effectively reduced, effectively reducing the shear force on the gasket 30, ensuring the overall structural stability of the gasket 30 after disassembly and assembly, and enabling the gasket 30 to be reused more effectively, thus improving the practicality and reliability of the electrolysis assembly 100.

[0038] See Figures 7 to 9 In one embodiment of this application, the gasket 30 includes a first sealing part 31 and a second sealing part 33. The second sealing part 33 is sleeved on the outer periphery of the first sealing part 31, and a protrusion 335 is provided on the surface of the second sealing part 33.

[0039] Understandably, see Figure 1 , Figure 2 and Figure 6The electrolysis assembly 100 can have positive electrode plates 50, negative electrode plates 70, and separators 90 stacked between the first frame 11 and the second frame 13, so that the electrolysis assembly 100 can better utilize the first frame 11 and the second frame 13 to form a closed electrolysis chamber, ensuring the stable operation of the electrolytic hydrogen production equipment. In some embodiments, the electrolysis assembly 100 can have the positive electrode plates 50 stacked on the surface of the first frame 11 facing the second frame 13, and the negative electrode plates 70 attached to the surface of the second frame 13 facing the first frame 11. The separator 90 can be placed between the positive electrode plates 50 and the negative electrode plates 70, and can be arranged to cover either the positive electrode plate 50 or the negative electrode plate 70, so that the separation of the positive electrode plates 50 and the negative electrode plates 70 by the separator 90 ensures the stable generation of hydrogen and oxygen in the electrolysis assembly 100 and reduces the mixing of generated hydrogen and oxygen.

[0040] In this embodiment, the gasket 30 may include a first sealing portion 31 and a second sealing portion 33. A protrusion 335 may be provided on the surface of the second sealing portion 33 to allow the second sealing portion 33 to engage and limit the electrode frame 10, ensuring a stable seal between the gasket 30 and the first frame 11 and the second frame 13, and preventing leakage from the electrode frame 10. At this time, by using the second sealing portion 33 to surround the first sealing portion 31, the first sealing portion 31 can separate the positive electrode plate 50 and the negative electrode plate 70 between the first frame 11 and the second frame 13. This allows the gasket 30 to separate the area where hydrogen is generated from the area where oxygen is generated within the electrode frame 10, effectively preventing the generated hydrogen and oxygen from mixing and ensuring stable electrolysis operation of the electrolysis assembly 100. Alternatively, the two opposing surfaces of the first sealing part 31 can be sealed to the positive electrode plate 50 and the diaphragm 90 respectively, so that the diaphragm 90 covers the superimposed negative electrode plate 70, thereby allowing the gasket 30 and the diaphragm 90 to better separate the positive electrode plate 50 and the negative electrode plate 70 into two independent closed chambers; or, the two opposing surfaces of the first sealing part 31 can be sealed to the negative electrode plate 70 and the diaphragm 90 respectively, so that the diaphragm 90 covers the superimposed positive electrode plate 50, thereby allowing the gasket 30 and the diaphragm 90 to better separate the positive electrode plate 50 and the negative electrode plate 70 into two independent closed chambers, ensuring the stable electrolysis operation of the electrolysis assembly 100.

[0041] With the cooperation and positioning of the second sealing part 33 and the electrode frame 10, the first sealing part 31 can be positioned by the second sealing part 33 sleeved on top of the first sealing part 31, effectively preventing the first sealing part 31 from detaching from the electrode frame 10. At the same time, with the sequential sealing action of the first sealing part 31 and the second sealing part 33, leakage of liquid and gas generated from the electrode frame 10 can be better prevented, further improving the practicality and structural reliability of the electrolysis assembly 100.

[0042] See Figure 8 and Figure 9 In one embodiment of this application, at least one of the surfaces of the first sealing part 31 facing the first frame 11 and the first sealing part 31 facing the second frame 13 is provided with a rib 315.

[0043] In this embodiment, the gasket 30 may have a rib 315 on the surface of the first sealing part 31. The rib 315 may be a surface protrusion structure integrally formed by the first sealing part 31, or it may be an elastic annular rib attached to the surface of the first sealing part 31. The rib 315 may undergo a certain elastic deformation during the assembly of the electrolysis assembly 100. This deformation of the rib 315 is beneficial to improve the pressing force between the gasket 30 and the electrode plate and the diaphragm 90, so that the first sealing part 31 can more stably press the electrode plate and the diaphragm 90, thereby achieving a better sealing effect of the gasket 30, effectively preventing the generated hydrogen and oxygen from mixing, and further improving the practicality and structural reliability of the electrolysis assembly 100.

[0044] The first sealing part 31 may have a rib 315 on the surface facing the first frame 11 so that the rib 315 presses against the electrode plate or diaphragm 90 on the surface of the first frame 11; or, the first sealing part 31 may have a rib on the surface facing the second frame 13 so that the rib 315 presses against the electrode plate or diaphragm 90 on the surface of the second frame 13; or, the first sealing part 31 may have ribs 315 on both the surface facing the first frame 11 and the surface facing the second frame 13 so that the first sealing part 31 can achieve a better sealing effect between the first frame 11 and the second frame 13, ensuring the stable operation of the electrolysis assembly 100.

[0045] See Figure 9 In one embodiment of this application, the first sealing part 31 includes a first ring body 311 and a first cover 313, the first cover 313 being disposed around the first ring body 311; the first ring body 311 is made of an elastic colloid material, and the first cover 313 is made of a corrosion-resistant material.

[0046] In this embodiment, the first ring body 311 can be made of elastic colloidal materials such as rubber or silicone. The first ring body 311 is wrapped by a first cover 313, which can be made of corrosion-resistant materials such as modified polytetrafluoroethylene, polyvinylidene fluoride, or corrosion-resistant flexible structural adhesive, capable of withstanding certain acids and alkalis. The corrosion resistance of the first cover 313 better protects the first ring body 311 from electrolyte erosion, ensuring the stable sealing of the first sealing part 31 within the electrode frame 10, and further improving the structural stability and reliability of the electrolysis assembly 100. Using the first cover 313 to wrap the first ring body 311 to form the first sealing part 31 allows the first sealing part 31 to use the lower-cost first ring body 311 as its main structure, which helps to reduce the production cost of the gasket 30 and further improves the practicality of the electrolysis assembly 100.

[0047] See Figure 9 In one embodiment of this application, the second sealing part 33 includes a second ring body 331 and a second cover 333, the second cover 333 being disposed around the second ring body 331; the second ring body 331 is made of an elastic colloid material, and the second cover 333 is made of a corrosion-resistant material.

[0048] In this embodiment, the second ring 331 can be made of elastic colloidal materials such as rubber or silicone. By wrapping the second ring 331 with a second cover 333, which can be made of corrosion-resistant materials such as modified polytetrafluoroethylene, polyvinylidene fluoride, or corrosion-resistant flexible structural adhesive, the corrosion resistance of the second cover 333 better protects the second ring 331 from electrolyte erosion, ensuring the stable sealing of the second sealing part 33 within the electrode frame 10, and further improving the structural stability and reliability of the electrolysis assembly 100. Using the second cover 333 to wrap the second ring 331 to form the second sealing part 33 allows the second sealing part 33 to use the lower-cost second ring 331 as its main structure, which helps to reduce the production cost of the gasket 30 and further improves the practicality of the electrolysis assembly 100.

[0049] See Figure 9 In one embodiment of this application, the second ring 331 includes at least two single rings 3311, which are sequentially and spaced apart.

[0050] In this embodiment, the second ring 331 can be composed of at least two sequentially spaced single rings 3311. The second cover 333 encloses at least two single rings 3311, creating a thinner connection structure between adjacent single rings 3311. This allows the second sealing part 33 to form a protrusion 335 around the single ring 3311, ensuring a stable engagement between the protrusion 335 and the limiting groove 15, thus improving the structural stability of the gasket 30. Using multiple sequentially spaced single rings 3311 to form the second sealing part 33 allows for better engagement of the second sealing part 33 with the limiting groove 15 to form the protrusion 335, facilitating the production and processing of the gasket 30 and further improving the practicality and structural reliability of the electrolysis assembly 100.

[0051] See Figure 3 and Figure 4 In one embodiment of this application, the first sealing part 31 and the second sealing part 33 are an integral structure.

[0052] In this embodiment, the gasket 30 can be constructed with the first and second sealing elements as a single unit. In this case, the first and second sealing elements can be integrally molded from corrosion-resistant materials such as modified polytetrafluoroethylene, polyvinylidene fluoride, or corrosion-resistant flexible structural adhesive, which can withstand certain acids and alkalis. Alternatively, when the first sealing portion 31 includes a first ring 311 and a first cover 313 enclosing the first ring 311, and the second sealing portion 33 includes a second ring 331 and a second cover 333 enclosing the second ring 331, the first cover 313 and the second cover 333 can be integrally molded, allowing the connected first cover 313 and second cover 333 to enclose the first ring 311 and the second ring 331 to form a single structure. By using the first sealing portion 31 and the second sealing portion 33 as a single unit, the overall structural stability and strength of the gasket 30 can be improved, facilitating the assembly and disassembly of the electrolysis assembly 100.

[0053] Furthermore, in other embodiments, the gasket 30 can be configured with a separate structure for the first sealing part 31 and the second sealing part 33, allowing the second sealing part 33 to be fitted around the first sealing part 31, ensuring the stable sealing effect of the gasket 30 within the pole frame 10. This separate gasket 30 design facilitates independent disassembly, maintenance, and replacement of the first sealing part 31 and the second sealing part 33, and also allows for misaligned assembly of the first sealing part 31 and the second sealing part 33 with the internal structural layout of the pole frame 10, for example… Figure 5As shown, the separate first sealing part 31 and second sealing part 33 can better enable the second sealing part 33 to engage with the protrusion 335 and the limiting groove 15, while ensuring the sealing of the first sealing part 31 with the electrode plate and the diaphragm 90. This effectively avoids the gasket 30 from being torn due to misalignment of the first sealing part 31 and the second sealing part 33, ensuring the overall structural stability of the gasket 30 and further improving the practicality and reliability of the electrolysis assembly 100.

[0054] The first sealing part 31 and the second sealing part 33 are configured as separate parts. The first sealing part 31 can be configured as a combination structure in which the first covering part 313 wraps around the first ring body 311, and the second sealing part 33 can be configured as a one-piece structure made of corrosion-resistant material. Alternatively, the first sealing part 31 can be configured as a one-piece structure made of corrosion-resistant material, and the second sealing part 33 can be configured as a combination structure in which the second covering part 333 wraps around the second ring body 331. Alternatively, the first sealing part 31 and the second sealing part 33 can each be configured as a one-piece structure made of corrosion-resistant material. Alternatively, the first sealing part 31 can be configured as a combination structure in which the first covering part 313 wraps around the first ring body 311, and the second sealing part 33 can be configured as a combination structure in which the second covering part 333 wraps around the second ring body 331.

[0055] See Figure 3 and Figure 4 In one embodiment of this application, the width of the limiting slot 15 is gradually reduced along the direction away from the washer 30.

[0056] In this embodiment, by gradually narrowing the width of the limiting groove 15, the limiting groove 15 can have a structure similar to a groove that is wider at the top and narrower at the bottom. This allows the protrusion 335 of the gasket 30 to engage with the limiting groove 15 more effectively, thanks to the wider groove opening. Furthermore, the mutual pressing of the first frame 11 and the second frame 13 allows the protrusion 335 to better abut and seal against the narrower part of the limiting groove 15, achieving a more convenient engagement and reducing indentations formed by the electrode frame 10 on the gasket 30. Simultaneously, the wider-at-the-top, narrower-at-the-bottom groove structure facilitates easier removal of the gasket 30 during disassembly of the electrolysis assembly 100, preventing the protrusion 335 from jamming with the limiting groove 15 and further enhancing the ease of assembly and disassembly and practicality of the electrolysis assembly 100.

[0057] See Figure 7 In one embodiment of this application, the washer 30 is provided with a flow channel hole 35, which is located on the side of the protrusion 335 away from the edge of the washer 30.

[0058] It is understood that the electrolysis assembly 100 can have interconnected openings on the electrode frame 10 and the gasket 30, respectively, to allow the electrolyte to flow into the space enclosed by the electrode frame 10 of the electrolysis assembly 100, and to allow the produced hydrogen and oxygen to be discharged, ensuring the stable operation of the electrolysis assembly 100. The opening on the gasket 30 can be a flow channel hole 35 penetrating the gasket 30. By positioning the flow channel hole 35 on the side of the protrusion 335 facing away from the edge of the gasket 30, the protrusion 335 can be engaged and sealed with the limiting groove 15, effectively preventing electrolyte or generated gas from leaking through the flow channel hole 35 from the gap between the gasket 30 and the electrode frame 10. This allows the electrolysis assembly 100 to achieve more stable and reliable operation, further improving the structural stability and reliability of the electrolysis assembly 100.

[0059] This application also proposes an electrolytic hydrogen production device, which includes a device body and an electrolysis component 100. The specific structure of the electrolysis component 100 is as described in the above embodiments. Since this electrolytic hydrogen production device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0060] The electrolytic hydrogen production equipment utilizes multiple first frames 11, second frames 13, and gaskets 30 to form a multi-layered electrolytic cell structure, allowing the positive electrode plate 50 and negative electrode plate 70 to be alternately arranged among the multiple electrolytic components 100. This enables faster and more reliable electrolysis operations. The equipment body can use two end plates to press the two ends of the integrated structure formed by the multiple electrolytic components 100, and positioning rods can pass through the multiple electrolytic components 100 and connect to the end plates to ensure the aligned assembly of the multiple electrolytic components 100. This better prevents electrolyte and gas leakage, achieving more stable and reliable electrolysis operations and improving the structural stability and reliability of the electrolytic hydrogen production equipment.

[0061] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
