[0002] In actual industrial production, to reduce the costs of hydrogen compression, storage, transportation, and refueling in subsequent processes, the pressure of hydrogen output from the hydrogen side of the electrolysis module is usually increased during the hydrogen production stage, thus eliminating the need for compressors in subsequent processes.

[0013] In some embodiments, each of the fuel cell stacks further includes a third seal disposed on the side of the non-metallic anode frame away from the anion exchange membrane, and the third seal abuts against the non-metallic anode frame and the metal inspection partition of two adjacent fuel cell stacks.

[0014] In some embodiments, a third sealing groove is provided on the side of the non-metallic anode frame away from the anion exchange membrane, and a third sealing element is disposed in the third sealing groove. The width of the third sealing groove is 1mm-5mm, and the depth of the third sealing groove is 0.1mm-3mm.

The first aspect is the issue of cracking; the second aspect is that the pressure-bearing capacity of the non-metallic anode frame can be adapted to the oxygen pressure, so that the non-metallic anode frame can maintain structural stability and reliability when the electrolysis module produces oxygen.

Thus, through the metal inspection partition and the non-metallic anode frame, the structure of the electrolysis module is adapted to the output pressure of the electrolysis module.

[0026] In actual industrial production, to reduce the costs of hydrogen compression, storage, transportation, and refueling in subsequent processes, the pressure of hydrogen output from the hydrogen side of the electrolysis module is typically increased during the hydrogen production stage, thus eliminating the need for compressors in subsequent processes. However, the pressure of oxygen output from the oxygen side of the electrolysis module usually only needs to be set to atmospheric pressure or slightly positive pressure to meet production requirements. In related technologies, the structures of the hydrogen and oxygen sides of the electrolysis module are symmetrically arranged, resulting in a mismatch between the structure and the output pressure.

[0027] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the electrolysis module 100 provided in the embodiments of this application. Figure 2 This is an exploded view of a portion of the structure of the electrolysis module 100 provided in this application embodiment. The electrolysis module 100 includes a first end assembly 10, a second end assembly 20, and multiple stack units 30. The second end assembly 20 is spaced apart from the first end assembly 10. The multiple stack units 30 are located between the first end assembly 10 and the second end assembly 20. The number of stack units 30 can be specifically set according to actual needs, and this application does not impose a specific limitation. Each stack unit 30 includes a metal inspection partition 31, a cathode diffusion layer 32, an anion exchange membrane 33, an anode diffusion layer 34, an anode flow field 35, and a non-metallic anode frame 36 arranged sequentially. The non-metallic anode frame 36 is provided with a receiving hole 361. The anode flow field 35 and the anode diffusion layer 34 are received in the receiving hole 361. The non-metallic anode frame 36 can be a plastic frame.

[0028] The electrolysis module 100 can be applied to the field of AEM (anion exchange membrane) water electrolysis for hydrogen production. Due to the high mechanical strength and high density of the anion exchange membrane 33, the portion between the metal inspection partition 31 and the anion exchange membrane 33 in the electrolysis module 100 can still enable the electrolysis module 100 to produce hydrogen normally while maintaining a high pressure. When the electrolysis module 100 is energized, the metal inspection partition 31 is connected to the negative terminal of the power supply, and the anode flow field 35 is connected to the positive terminal. Under the action of the electric field, the liquid between the metal inspection partition 31 and the anion exchange membrane 33 decomposes to produce hydrogen, and the liquid between the anode flow field 35 and the anion exchange membrane 33 decomposes to produce oxygen. The anode flow field 35 can be configured as a metallic structure to improve its electrical conductivity.

[0029] In this embodiment, each fuel cell stack unit 30 includes a metal inspection partition 31, a cathode diffusion layer 32, an anion exchange membrane 33, an anode diffusion layer 34, an anode flow field 35, and a non-metallic anode frame 36 arranged sequentially. Firstly, the metal inspection partition 31 made of metal can improve the mechanical strength and creep resistance of the metal inspection partition 31, improve the pressure bearing capacity of the metal inspection partition 31, and make the pressure bearing capacity of the metal inspection partition 31 compatible with the hydrogen pressure, so that the structure of the electrolysis module 100 remains stable and reliable during the electrolysis of hydrogen production, and avoid the problems of structural deformation, damage, and breakage of the metal inspection partition 31. Secondly, the non-metallic anode frame 36, made of non-metallic material, has a pressure-bearing capacity that can be adapted to oxygen pressure, enabling the non-metallic anode frame 36 to maintain structural stability and reliability during the electrolysis of oxygen by the electrolysis module 100. At the same time, it can also reduce the weight of the non-metallic anode frame 36, thereby reducing the overall weight of the electrolysis module 100, reducing material waste, reducing the overall manufacturing cost of the electrolysis module 100, and reducing the difficulty of hoisting, assembling, and transporting the electrolysis module 100. Thus, through the metal inspection partition 31 and the non-metallic anode frame 36, the structure of the electrolysis module 100 is adapted to the output pressure of the electrolysis module 100.

[0030] Compared to methods where both the inspection partition and the anode frame are made of metal, in this embodiment, the metal inspection partition 31 and the non-metallic anode frame 36 avoid the over-design problem of the electrolysis module 100, reducing the weight and production cost of the non-metallic anode frame 36, thereby optimizing the structure of the electrolysis module 100 and reducing its overall weight and manufacturing cost. Furthermore, the non-metallic anode frame 36 provides flexible structural compensation for the seal between the metal inspection partition 31, the anion exchange membrane 33, and the non-metallic anode frame 36. When the electrolysis module 100 is operating, when the pressure between the metal inspection partition 31 and the anion exchange membrane 33 increases, the non-metallic anode frame 36 can elastically deform under pressure, making the sealing connection between the metal inspection partition 31, the anion exchange membrane 33, and the non-metallic anode frame 36 tighter, improving the sealing effect and reducing the risk of leakage.

[0031] In configurations where both the inspection baffle and the anode frame are non-metallic, the non-metallic inspection baffle suffers from insufficient mechanical strength and creep resistance when facing high-pressure hydrogen output from the hydrogen side. This leads to deformation and cracking of the non-metallic inspection baffle during production, causing the electrolysis module to fail and preventing normal operation. In this embodiment, the metallic inspection baffle 31 and the non-metallic anode frame 36 enable the electrolysis module 100 to adapt to the production requirements of high-pressure hydrogen output from the hydrogen side, thereby reducing hydrogen production costs.

[0032] The hydrogen production pressure of the electrolysis module 100 is greater than or equal to 1 MPa, and the oxygen production pressure is less than 1 MPa. By ensuring the hydrogen production pressure of the electrolysis module 100 is greater than or equal to 1 MPa, the costs of hydrogen compression, storage, transportation, and refueling in subsequent processes can be reduced, eliminating the need for compressors in subsequent processes and thus reducing hydrogen production costs. The hydrogen production pressure can be specifically set according to actual needs, and this application does not impose a specific limitation. For example, the hydrogen production pressure can be 1.1 MPa, 1.2 MPa, 1.3 MPa, 1.4 MPa, 1.5 MPa, 1.6 MPa, 1.7 MPa, 1.8 MPa, 1.9 MPa, 2.0 MPa, etc.

[0033] The electrolysis module 100 is connected to a first gas collecting pipe (not shown) and a second gas collecting pipe (not shown). The first gas collecting pipe is connected between the metal inspection partition 31 and the anion exchange membrane 33, and is used to collect hydrogen generated during the operation of the electrolysis module 100. The second gas collecting pipe is connected between the non-metallic anode frame 36 and the anion exchange membrane 33, and is used to collect oxygen generated during the operation of the electrolysis module 100. The hydrogen production pressure can be the hydrogen pressure in the first gas collecting pipe. The oxygen production pressure can be the oxygen pressure in the second gas collecting pipe. In some embodiments, the hydrogen production pressure can also be the hydrogen pressure at the hydrogen outlet of the electrolysis module 100 located between the metal inspection partition 31 and the anion exchange membrane 33, and the oxygen production pressure can also be the oxygen pressure at the oxygen outlet of the electrolysis module 100 located between the non-metallic anode frame 36 and the anion exchange membrane 33.

[0034] Please refer to the following: Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 3 This is a partial cross-sectional view of the electrolysis module 100 provided in an embodiment of this application. Figure 4 This is a partial structural schematic diagram of the metal inspection partition 31 provided in an embodiment of this application. Figure 5 This is a partial structural schematic diagram of the anode flow field 35 provided in an embodiment of this application. A plurality of first flow channels 311 are provided on the side of the metal inspection partition 31 facing the cathode diffusion layer 32. These first flow channels 311 form channels for liquid flow, facilitating liquid flow between the metal inspection partition 31 and the cathode diffusion layer 32. A plurality of second flow channels 351 are provided on the side of the anode flow field 35 facing the anode diffusion layer 34. These second flow channels 351 form channels for liquid flow, facilitating liquid flow between the anode flow field 35 and the anode diffusion layer 34. The first flow channels 311 and the second flow channels 351 can be formed by processes such as etching, machining, and stamping.

[0035] For example, the first flow channels 311 may extend in a straight line, and multiple first flow channels 311 may be arranged in parallel to form a parallel flow field structure on the metal inspection baffle 31. In some embodiments, the first flow channels 311 may also extend in a serpentine manner to form a serpentine flow field structure on the metal inspection baffle 31. In some embodiments, multiple first flow channels 311 may also be arranged in an alternating pattern to form a grid flow field structure on the metal inspection baffle 31. In some embodiments, multiple first flow channels 311 may also be arranged in a biomimetic pattern to form a biomimetic flow field structure on the metal inspection baffle 31.

[0036] The second flow channel 351 can be configured in the same way or differently from the first flow channel 311. The second flow channel 351 can extend in a straight line, extend in a serpentine shape, be arranged in an interlaced manner, or be arranged in a biomimetic shape, so as to form a parallel flow field, a serpentine flow field, a grid flow field, or a biomimetic flow field on the anode flow field 35.

[0037] For example, the depth L11 of the first flow channel 311 can be 0.3mm-2mm, and the width L12 of the first flow channel 311 can be 1mm-8mm, so that the first flow channel 311 has good flow guiding ability, avoiding difficulties in liquid flow due to the depth L11 and width L12 of the first flow channel 311 being too small, and avoiding insufficient flow guiding and diversion ability of the liquid due to the depth L11 and width L12 of the first flow channel 311 being too large. The depth L11 and width L12 of the first flow channel 311 can be specifically set according to actual needs, and are not specifically limited in this application. For example, the depth L11 of the first flow channel 311 can be 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.2mm, 1.4mm, 1.5mm, 1.6mm, 1.8mm, 2mm, etc. The width L12 of the first flow channel 311 can be 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, etc.

[0038] For example, the depth L21 of the second flow channel 351 can be 0.3mm-2mm, and the width L22 of the second flow channel 351 can be 1mm-8mm, so that the second flow channel 351 has good flow guiding ability, avoiding difficulties in liquid flow due to the depth L21 and width L22 of the second flow channel 351 being too small, and avoiding insufficient flow guiding and diversion ability of the liquid due to the depth L21 and width L22 of the second flow channel 351 being too large. The depth L21 and width L22 of the second flow channel 351 can be specifically set according to actual needs, and are not specifically limited in this application. For example, the depth L21 of the second flow channel 351 can be 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.2mm, 1.4mm, 1.5mm, 1.6mm, 1.8mm, 2mm, etc. The width L22 of the second flow channel 351 can be 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, etc.

[0039] Please refer to the following: Figure 2 and Figure 6 , Figure 6 This is a partial cross-sectional view of the fuel cell unit 30 provided in an embodiment of this application. Figure 6This is a cross-sectional view of the fuel cell stack unit 30 in the decomposed state. Each fuel cell stack unit 30 also includes a first seal 312. The first seal 312 abuts against the metal inspection partition 31 and the anion exchange membrane 33 to seal the first cavity formed between the metal inspection partition 31 and the anion exchange membrane 33, thereby preventing hydrogen leakage and ensuring the safe operation of the electrolysis module 100.

[0040] In some embodiments, the first seal 312 and the metal inspection partition 31 can be integrally formed to improve the tightness of the connection between them, enhance sealing reliability, reduce leakage risk, and solve the problem of unreliable connection between the first seal 312 and the metal inspection partition 31 due to material differences. Furthermore, by integrating the first seal 312 and the metal inspection partition 31 into a single unit, the problem of poor sealing performance caused by displacement of the first seal 312 during assembly of the electrolysis module 100 can be addressed. The first seal 312 and the metal inspection partition 31 can be formed into a single unit through injection molding or dispensing processes, thereby reducing the risk of leakage due to unreliable connection. In some embodiments, the first seal 312 and the metal inspection partition 31 can also be formed into a single unit through other processes.

[0041] For example, the first seal 312 and the metal inspection partition 31 can be integrally formed by injection molding. During molding, the metal inspection partition 31 is placed in the injection mold, molten rubber material is injected into the mold, and after the mold cools, the integrally formed metal inspection partition 31 and the first seal 312 are removed. The rubber material can be, but is not limited to, fluororubber, EPDM rubber, and silicone.

[0042] In some embodiments, the first seal 312 and the metal inspection partition 31 can be formed as a single unit through a dispensing process. During molding, liquid sealant is applied to the metal inspection partition 31 in a continuous circular pattern using an automatic dispensing device. The sealant is then cured by allowing it to stand at room temperature, under ambient light, or under ultraviolet light to form the first seal 312. The width of the sealant application can be 1mm-5mm, and the height can be 0.2mm-6mm. The width and height of the sealant application can be specifically set according to actual needs and are not specifically limited in this application. For example, the width of the sealant application can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc. The application height of the sealant can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, etc.

[0043] In some embodiments, the first sealing element 312 and the metal inspection partition 31 can be separately configured to simplify the manufacturing process of the first sealing element 312 and the metal inspection partition 31 and reduce the manufacturing cost of the electrolysis module 100. The first sealing element 312 can be configured as a sealing gasket, which is independently configured with respect to the metal inspection partition 31. The sealing gasket is sandwiched between the metal inspection partition 31 and the anion exchange membrane 33, and a seal is formed between the metal inspection partition 31 and the anion exchange membrane 33 by clamping the sealing gasket.

[0044] In some embodiments, the metal inspection partition 31 is provided with a first sealing groove 313. A first sealing element 312 is disposed within the first sealing groove 313. After the electrolysis module 100 is assembled, the sidewall of the first sealing groove 313 is used to abut against the first sealing element 312 to limit the deformation of the first sealing element 312, increase the contact force between the first sealing element 312 and the anion exchange membrane 33, improve the sealing effect, and reduce the risk of leakage. The first sealing groove 313 is also used to position the first sealing element 312 so that when the metal inspection partition 31 is injection molded, glued, or when the sealing gasket is assembled with the metal inspection partition 31, the first sealing element 312 is easily aligned with the metal inspection partition 31, reducing the difficulty of molding and assembly.

[0045] The width W1 of the first sealing groove 313 can be 1mm-5mm, and the depth D1 of the first sealing groove 313 can be 0.1mm-3mm. The width W1 and depth D1 of the first sealing groove 313 can be specifically set according to actual needs, for example, according to the width and height of the first sealing member 312 (the dimension of the first sealing member 312 along the direction of the metal inspection partition 31 toward the anion exchange membrane 33), and are not specifically limited in this application. For example, the width W1 of the first sealing groove 313 can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc. The depth D1 of the first sealing groove 313 can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, etc. The depth D1 of the first sealing groove 313 is less than the height of the first sealing member 312, so that the first sealing member 312 protrudes relative to the first sealing groove 313, so that the first sealing member 312 abuts against the anion exchange membrane 33.

[0046] In some embodiments, the seal between the first seal 312 and the anion exchange membrane 33 is a line seal, forming a continuous sealing line to prevent leakage points between the first seal 312 and the anion exchange membrane 33. The first seal 312 is annularly arranged, and its annular shape can be adapted to the shape of the metal inspection partition 31. In some embodiments, there may be one first seal 312. In some embodiments, there may be multiple first seals 312 arranged in a nested configuration, forming a concentric arrangement, with the outer first seal 312 surrounding the inner first seal 312, and adjacent first seals 312 spaced apart.

[0047] The cross-sectional shape of the first seal 312 can be trapezoidal or semi-circular. For example, Figure 6 The cross-sectional shape of the first sealing element 312 is illustrated using a semi-circular shape as an example. When the first sealing element 312 is compressed, the inclined side of the trapezoid and the arc-shaped side of the semi-circle can bulge outward and deform, compressing the sidewall of the first sealing groove 313.

[0048] In some embodiments, each stack unit 30 further includes a second seal 362. The second seal 362 abuts against the non-metallic anode frame 36 and the anion exchange membrane 33. The second seal 362 and the anion exchange membrane 33 are sealed together to seal the second cavity formed between the anode flow field 35, the non-metallic anode frame 36 and the anion exchange membrane 33, thereby preventing oxygen leakage and ensuring the safe operation of the electrolysis module 100.

[0049] In some embodiments, the second seal 362 and the non-metallic anode frame 36 can be integrally formed to improve the tightness of the connection between them, enhance sealing reliability, reduce leakage risk, and solve the problem of poor sealing performance caused by displacement of the second seal 362 during electrolysis module 100 assembly, thus integrating the second seal 362 and the non-metallic anode frame 36 into a single unit. Compared to a metallic anode frame, both the non-metallic anode frame 36 and the second seal 362 are non-metallic structures, which further improves the tightness of the connection between them, enhances sealing performance, and reduces the risk of leakage in the electrolysis module 100. The second seal 362 and the non-metallic anode frame 36 can be integrated using injection molding or dispensing processes, thereby reducing the risk of leakage due to unreliable connection between them. In some embodiments, the second seal 362 and the non-metallic anode frame 36 can also be formed as a whole through other processes.

[0050] For example, the second seal 362 and the non-metallic anode frame 36 can be integrally formed by injection molding. During molding, the non-metallic anode frame 36 is placed in an injection mold, molten rubber material is injected into the mold, and after the mold cools, the integrally formed non-metallic anode frame 36 and the second seal 362 are removed. The rubber material can be, but is not limited to, fluororubber, EPDM rubber, and silicone.

[0051] In some embodiments, the second seal 362 and the non-metallic anode frame 36 can be integrally formed through a dispensing process. During molding, liquid sealant is applied to the non-metallic anode frame 36 in a continuous circular pattern using an automatic dispensing device. The sealant is then cured by allowing it to stand at room temperature, under ambient light, or under ultraviolet light to form the second seal 362. The width of the sealant application can be 1mm-5mm, and the height can be 0.2mm-6mm. The width and height of the sealant application can be specifically set according to actual needs and are not specifically limited in this application. For example, the width of the sealant application can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc. The application height of the sealant can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, etc.

[0052] In some embodiments, the second seal 362 and the non-metallic anode frame 36 can be separately configured to simplify the manufacturing process of the second seal 362 and the non-metallic anode frame 36, and reduce the manufacturing cost of the electrolysis module 100. The second seal 362 can be configured as a sealing gasket, which is independently configured with respect to the non-metallic anode frame 36. The sealing gasket is sandwiched between the non-metallic anode frame 36 and the anion exchange membrane 33, and a seal is formed between the non-metallic anode frame 36 and the anion exchange membrane 33 by clamping the sealing gasket. The second seal 362 includes a first sealing portion 3621 and a second sealing portion 3622. The first sealing portion 3621 is planar on the side facing the anion exchange membrane 33 and is positioned opposite the first sealing member 312. This planar arrangement provides support for the anion exchange membrane 33, creating a stable sealing interface between the first sealing member 312 and the anion exchange membrane 33, and providing flexible support to the anion exchange membrane 33, reducing the risk of damage at the contact point between the anion exchange membrane 33 and the first sealing member 312. The second sealing portion 3622 is connected to the side of the first sealing portion 3621 facing the non-metallic anode frame 36 and abuts against the non-metallic anode frame 36. The second sealing portion 3622 is trapezoidal or semi-circularly protruding.

[0053] In some embodiments, a second sealing groove 363 is provided on the non-metallic anode frame 36 at the position corresponding to the second sealing portion 3622. After the electrolysis module 100 is assembled, the second sealing element 362 is disposed in the second sealing groove 363. The groove sidewall of the second sealing groove 363 is used to abut against the second sealing element 362 to increase the contact area between the second sealing element 362 and the non-metallic anode frame 36, thereby improving the sealing effect after the second sealing element 362 abuts against the non-metallic anode frame 36 and reducing the risk of leakage problems.

[0054] The second sealing groove 363 is also used to position the second sealing element 362, so as to facilitate the alignment of the second sealing element 362 with the metal inspection partition 31 when the non-metallic anode frame 36 is injection molded, glued, or when the sealing gasket is assembled with the non-metallic anode frame 36, reducing the difficulty of molding and assembly. When the second sealing element 362 is integrally set with the non-metallic anode frame 36, the second sealing element 362 is fixed to the bottom wall of the second sealing groove 363 and protrudes towards the anion exchange membrane 33 relative to the second sealing groove 363. When the second sealing element 362 and the non-metallic anode frame 36 are separately set, the second sealing part 3622 of the second sealing element 362 is disposed within the second sealing groove 363, and the first sealing part 3621 of the second sealing element 362 is located outside the second sealing groove 363 and sandwiched between the non-metallic anode frame 36 and the anion exchange membrane 33.

[0055] The width W2 of the second sealing groove 363 can be 1mm-5mm, and the depth D2 of the second sealing groove 363 can be 0.1mm-3mm. The width W2 and depth D2 of the second sealing groove 363 can be specifically set according to actual needs, for example, based on the width and height of the second sealing member 362 (the dimension of the second sealing member 362 along the direction from the non-metallic anode frame 36 towards the anion exchange membrane 33), and are not specifically limited in this application. For example, the width W2 of the second sealing groove 363 can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc. The depth D2 of the second sealing groove 363 can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, etc. The depth D2 of the second sealing groove 363 is less than the height of the second sealing member 362, so that the second sealing member 362 protrudes relative to the second sealing groove 363, so that the second sealing member 362 abuts against the anion exchange membrane 33.

[0056] In some embodiments, the second seal 362 is annularly arranged, and the annular shape of the second seal 362 can be adapted to the shape of the non-metallic anode frame 36. In some embodiments, there may be one second seal 362. In some embodiments, there may also be multiple second seals 362 arranged in a nested configuration to form a concentric arrangement, with the outer second seal 362 surrounding the periphery of the inner second seal 362, and adjacent second seals 362 spaced apart.

[0057] When the second seal 362 and the non-metallic anode frame 36 are separately disposed, the sealing form between the second sealing portion 3622 of the second seal 362 and the non-metallic anode frame 36 is a line seal to avoid leakage points between the second seal 362 and the non-metallic anode frame 36. The cross-sectional shape of the second sealing portion 3622 can be trapezoidal or semi-circular. For example, Figure 6 The cross-sectional shape of the second sealing part 3622 is illustrated using a trapezoidal shape as an example. When the second sealing part 3622 is compressed, the inclined side of the trapezoid and the semi-circular arc side can bulge outward and deform, compressing the sidewall of the second sealing groove 363, thereby improving the sealing effect between the second sealing part 3622 and the non-metallic anode frame 36.

[0058] In some embodiments, each fuel cell stack 30 further includes a third seal 364. The third seal 364 is disposed on the side of the non-metallic anode frame 36 facing away from the anion exchange membrane 33. The third seal 364 abuts between the non-metallic anode frame 36 and the metallic inspection partition 31 of two adjacent fuel cell stack 30 to form a seal between the two adjacent fuel cell stack 30.

[0059] In some embodiments, the third seal 364 and the non-metallic anode frame 36 can be integrally formed to improve the tightness of the connection between them, enhance sealing reliability, reduce leakage risk, and integrate them into a single unit. This addresses the problem of poor sealing performance caused by displacement of the third seal 364 during electrolysis module 100 assembly. The third seal 364 and the non-metallic anode frame 36 can be integrated using injection molding or dispensing processes, thereby reducing the risk of leakage due to unreliable connection. In some embodiments, the third seal 364 and the non-metallic anode frame 36 can also be integrated using other processes.

[0060] For example, the third seal 364 and the non-metallic anode frame 36 can be integrally formed by injection molding. During molding, the non-metallic anode frame 36 is placed in an injection mold, molten rubber material is injected into the mold, and after the mold cools, the integrally formed non-metallic anode frame 36 and the third seal 364 are removed. The rubber material can be, but is not limited to, fluororubber, EPDM rubber, and silicone.

[0061] In some embodiments, the third seal 364 and the non-metallic anode frame 36 can be integrally formed through a dispensing process. During molding, liquid sealant is applied to the non-metallic anode frame 36 in a continuous circular pattern using an automatic dispensing device. The sealant is then cured by standing at room temperature, exposure to ambient light, or ultraviolet radiation to form the third seal 364. The width of the sealant application can be 1mm-5mm, and the height can be 0.2mm-6mm. The width and height of the sealant application can be specifically set according to actual needs and are not specifically limited in this application. For example, the width of the sealant application can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc. The application height of the sealant can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, etc.

[0062] In some embodiments, the third seal 364 and the non-metallic anode frame 36 may be separately configured to simplify the manufacturing process of the third seal 364 and the non-metallic anode frame 36 and reduce the manufacturing cost of the electrolysis module 100. The third seal 364 may be configured as a sealing gasket, which is independently configured with respect to the non-metallic anode frame 36 and sandwiched between the non-metallic anode frames 36 and the metal inspection partition 31 of two adjacent stack units 30.

[0063] In some embodiments, in each fuel cell stack unit 30, a third sealing groove 365 is provided on the side of the non-metallic anode frame 36 facing away from the anion exchange membrane 33. A third sealing element 364 is disposed within the third sealing groove 365. After the electrolysis module 100 is assembled, the sidewall of the third sealing groove 365 abuts against the third sealing element 364 to limit the deformation of the third sealing element 364, increase the contact force between the third sealing element 364 and the metal inspection partition 31 of the adjacent fuel cell stack unit 30, improve the sealing effect, and reduce the risk of leakage. The third sealing groove 365 is also used to position the third sealing element 364 so that when the non-metallic anode frame 36 is injection molded, glued, or when the sealing gasket is assembled with the non-metallic anode frame 36, the third sealing element 364 and the non-metallic anode frame 36 are aligned, reducing the difficulty of molding and assembly. In each fuel cell stack unit 30, the side of the metal inspection partition 31 facing away from the anion exchange membrane 33 can be planar.

[0064] The width W3 of the third sealing groove 365 can be 1mm-5mm, and the depth D3 of the third sealing groove 365 can be 0.1mm-3mm. The width W3 and depth D3 of the third sealing groove 365 can be specifically set according to actual needs, for example, based on the width and height of the third sealing element 364 (the dimension of the third sealing element 364 along the direction from the non-metallic anode frame 36 towards the anion exchange membrane 33), and are not specifically limited in this application. For example, the width W3 of the third sealing groove 365 can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc., and the depth D3 of the third sealing groove 365 can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, etc. The depth D3 of the third sealing groove 365 is less than the height of the third sealing member 364, so that the third sealing member 364 protrudes relative to the third sealing groove 365, so that the third sealing member 364 abuts against the metal inspection partition 31 of the adjacent fuel cell unit 30.

[0065] In some embodiments, the seal between the third seal 364 and the anion exchange membrane 33 is a line seal to form a continuous sealing line, preventing leakage points between the third seal 364 and the metal inspection partition 31 of the adjacent fuel cell unit 30. The third seal 364 is annularly arranged, and its annular shape can be adapted to the shape of the non-metallic anode frame 36. In some embodiments, there may be one third seal 364. In some embodiments, there may be multiple third seals 364 arranged in a nested configuration, forming a concentric arrangement, with the outer third seal 364 surrounding the inner third seal 364, and adjacent third seals 364 spaced apart.

[0066] The cross-sectional shape of the third seal 364 can be trapezoidal or semi-circular. For example, Figure 6 The cross-sectional shape of the third seal 364 is illustrated using a semi-circular shape as an example. When the third seal 364 is compressed, the inclined side of the trapezoid and the arc-shaped side of the semi-circle can bulge outward and deform, compressing the sidewall of the third sealing groove 365.

[0067] Please refer to the following: Figure 2 and Figure 3 The cathode diffusion layer 32 includes a cathode support portion 321 and a cathode diffusion portion 322. The cathode support portion 321 is disposed on the side of the cathode diffusion portion 322 near the metal inspection partition 31. The porosity of the cathode support portion 321 is less than that of the cathode diffusion layer 32. The cathode support portion 321 is used to support the cathode diffusion portion 322 to improve the overall structural strength of the cathode diffusion layer 32. The cathode diffusion portion 322 is used to conduct electrons, increase the contact area with the liquid, and improve the electrolysis efficiency. In some embodiments, the cathode support portion 321 and the cathode diffusion portion 322 can be integrally disposed. In some embodiments, the cathode support portion 321 and the cathode diffusion portion 322 can also be separately disposed, and the cathode support portion 321 and the cathode diffusion portion 322 are independently disposed.

[0068] In some embodiments, the cathode diffusion layer 32 further includes a cathode catalyst section, in which a catalyst for improving electrolysis efficiency is disposed. In some embodiments, the cathode catalyst layer and the cathode diffusion section 322 may be integrally disposed, or the cathode catalyst layer and the cathode diffusion section 322 may be separately disposed, with the cathode catalyst layer and the cathode diffusion section 322 being disposed independently of each other.

[0069] The anode diffusion layer 34 includes an anode support portion 341 and an anode diffusion portion 342. The anode support portion 341 is disposed on the side of the anode diffusion portion 342 near the anode flow field 35. The porosity of the anode support portion 341 is less than that of the anode diffusion layer 34. The anode support portion 341 is used to support the anode diffusion portion 342 to improve the overall structural strength of the anode diffusion layer 34. The anode diffusion portion 342 is used to conduct electrons, increase the contact area with the liquid, and improve the electrolysis efficiency. In some embodiments, the anode support portion 341 and the anode diffusion portion 342 can be integrally disposed. In some embodiments, the anode support portion 341 and the anode diffusion portion 342 can also be separately disposed, and the anode support portion 341 and the anode diffusion portion 342 are disposed independently of each other.

[0070] In some embodiments, the anode diffusion layer 34 further includes an anode catalyst portion, in which a catalyst for improving electrolysis efficiency is disposed. In some embodiments, the anode catalyst layer and the anode diffusion layer 342 may be integrally disposed, or the anode catalyst layer and the anode diffusion layer 342 may be separately disposed, with the anode catalyst layer and the anode diffusion layer 342 being disposed independently of each other.

[0071] Please refer to the following: Figure 2 and Figure 7 , Figure 7 This is a schematic diagram of the anion exchange membrane 33 provided in this embodiment.

The frame portion 331 is sandwiched between the metal inspection partition 31 and the non-metallic anode frame 36. The main body portion 332 is a functional component of the anion exchange membrane 33, performing the function of anion exchange. During water electrolysis in the electrolysis module 100, the anion exchange area is concentrated in the portion of the anion exchange membrane 33 opposite to the cathode diffusion layer 32 and the anode diffusion layer 34. The anion exchange rate is lower and the efficiency is lower in the portion of the anion exchange membrane 33 opposite to the non-metallic anode frame 36. In this embodiment, the frame portion 331 is used to protect the main body portion 332, and the frame portion 331 reduces the area of ​​the main body portion 332 used for anion exchange in the anion exchange membrane 33, thereby reducing the manufacturing cost of the anion exchange membrane 33 and the overall manufacturing cost of the electrolysis module 100. The frame portion 331 may be made of one or more of the following materials, but not limited to: polyphenylene sulfone (PPSU), polyphenylene sulfide (PPS), polyether ether ketone (PEEK), fluorinated ethylene propylene copolymer (FEP), or polytetrafluoroethylene (PTFE).

[0072] The first sealing element 312 and the second sealing element 362 abut against the opposite sides of the frame portion 331 so as to achieve a sealed contact between the metal inspection partition 31, the anion exchange membrane 33, and the non-metallic anode frame 36 through the frame portion 331.

[0073] In some embodiments, the anion exchange membrane 33 may further include a first catalyst section and a second catalyst section. The first catalyst section is disposed on the side of the main body 332 facing the cathode diffusion layer 32. The second catalyst section is disposed on the side of the main body 332 facing the anode diffusion layer 34.

A plurality of fuel cell stack units 30 are disposed between the cathode current collector 13 and the anode current collector 23. The anode insulating plate 22 is used to form insulation between the second end plate 21 and the anode current collector 23.

[0076] The electrolysis module 100 also includes a connector 371, a fixing member 372, and an elastic member 373.
