Description

Technical Field

[0001] The present invention relates to the technical field of electrolytic cell structures, in particular to a three-dimensional porous flow field plate electrolytic cell structure. Background Art

[0002] The three-dimensional porous flow field plate electrolyzer is a key device used for electrochemical reactions such as water electrolysis to produce hydrogen. Its core component, the three-dimensional porous flow field plate, acts like a city's underground pipe network, ensuring uniform electrolyte distribution to each reaction cell through a carefully designed three-dimensional network of channels. This unique structure facilitates smoother electrolyte flow, much like how a highway interchange improves traffic flow efficiency over a flat road. This significantly improves the uniformity and efficiency of the electrolysis reaction. The porous structure within the electrolyzer acts like countless micro-pumps within the reaction area, promoting electrolyte penetration through capillary action, much like tree roots absorb water and nutrients through countless tiny root fibers, ensuring sufficient contact between reactants and the electrode surface. The three-dimensional design of the flow field plate also resembles the air duct layout of an air conditioning system, effectively controlling the reaction temperature distribution and preventing localized overheating. During the hydrogen production process, this electrolyzer acts like a sophisticated chemical plant, converting electrical energy into chemical energy more efficiently by optimizing fluid distribution and reaction interfaces. Its performance directly impacts hydrogen production and energy consumption. Traditional flat-plate electrolyzers have problems such as uneven reaction and bubble retention, just like a traffic jam at an intersection will reduce overall traffic efficiency. The introduction of three-dimensional porous structures is precisely to solve these key problems that restrict electrolysis efficiency.

[0003] In existing electrolyzer structures, the installation and positioning accuracy of the three-dimensional porous flow field plate stack directly affects electrolysis efficiency and equipment life. However, traditional fixing methods have significant drawbacks: First, insufficient mechanical positioning accuracy leads to uneven electrolyte distribution. Just as leaks at water pipe joints reduce water delivery efficiency, positioning deviations can cause uneven electrolysis reactions. Second, conventional clamping mechanisms lack adaptive capabilities, and gaps can form due to thermal deformation of the material over long-term operation. This is similar to a loose bicycle chain that affects transmission efficiency and can lead to poor contact in the stack. Third, existing locking mechanisms are unreliable and prone to displacement under vibration conditions, similar to an unlocked door swaying in the wind. Stack shifting can cause localized overheating. Finally, the overall structure is difficult to maintain, requiring specialized tools for disassembly, similar to repairing a complex mechanical watch, which increases maintenance costs and time. The essence of these problems lies in the fact that existing technologies fail to organically integrate key elements such as precise positioning, reliable locking, adaptive clamping, and convenient maintenance. This results in limited electrolyzer performance, insufficient operational stability, and high maintenance costs, severely restricting the development and application of electrolysis technology.

[0004] In view of this, we propose a three-dimensional porous flow field plate electrolyzer structure. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] A three-dimensional porous flow field plate electrolytic cell structure, such as Figure 1 - Figure 8As shown, it includes an electrolytic cell base 1, and a three-dimensional porous flow field plate stack 4 is arranged above the electrolytic cell base 1; it also includes a control component 2, which is used to align and position the three-dimensional porous flow field plate stack 4 during installation; a linkage component 3, which is used to ensure that the three-dimensional porous flow field plate stack 4 can be pressed tightly and will not deviate when the control component 2 positions the three-dimensional porous flow field plate stack 4; the control component 2 includes a bottom plate 21, the top surface of the bottom plate 21 is in contact with the bottom surface of the electrolytic cell base 1, and the inner side of the electrolytic cell base 1 is rotatably connected to a toggle disk 22, the surface of the toggle disk 22 is provided with a toggle groove 23, the bottom surface of the toggle disk 22 is fixedly connected to a ratchet 24, and the interior of the electrolytic cell base 1 is provided with a movable cavity 25, the inner side of the movable cavity 25 is slidably connected to a linkage plate 26, the bottom surface of the linkage plate 26 is fixedly connected to a toggle rod 27, and the bottom end of the toggle rod 27 is inserted into the toggle groove 23 provided on the surface of the toggle disk 22.

A linkage rod 29 is fixedly connected to the top surface of the linkage plate 26. A limit slot 215 is defined on the inside of the electrolytic cell base 1, and the linkage rod 29 is inserted into the limit slot 215. When the toggle disk 22 is rotated, the toggle slot 23 on its surface drives the toggle rod 27 to move. The toggle rod 27 is fixedly connected to the linkage plate 26, pushing the linkage plate 26 to slide along the guide rod 214. The spring 28 sleeved on the guide rod 214 provides a return force, ensuring smooth transmission. The linkage plate 26 drives the linkage rod 29 to slide within the limit slot 215. The interference rod 210 fixed on the linkage rod 29 smoothly pushes the three-dimensional porous flow field plate stack 4 to the predetermined position through its arc-shaped end surface, and the linkage rod 29 is slidably connected to the limiting groove 215. The linkage rod 29 is penetrated by the interference rod 210, and the linkage rod 29 is fixedly connected to the interference rod 210. Since the linkage rod 29 is inserted into the inner side of the limiting groove 215 and is slidably connected to the limiting groove 215, the limiting groove 215 will relatively limit the linkage rod 29, ensuring that the limiting groove 215 accurately controls the movement trajectory of the linkage rod 29 and ensures positioning accuracy.

At this time, the dial 22 can rotate freely, which is convenient for adjusting the position of the battery stack, and the external resistance rod 210 can reduce the manual alignment work of the multi-layer three-dimensional porous flow field plate.

[0023] The linkage assembly 3 includes a lifting groove 31, which is opened on the inner side of the linkage rod 29. A slider 32 is passed through the inner side of the lifting groove 31, and the slider 32 is slidably connected to the lifting groove 31. A limiting rod 34 is fixedly connected to the inner side of the lifting groove 31, and the limiting rod 34 passes through the slider 32 and is slidably connected. A spring three 35 is sleeved on the outer side of the limiting rod 34, and one end of the spring three 35 is fixedly connected to the inner side of the lifting groove 31, and the other end of the spring three 35 is fixedly connected to the top surface of the slider 32. The side of the slider 32 is fixedly connected with a second guide rod 33, and the inner side of the limit groove 215 is provided with a guide groove 38. The second guide rod 33 is inserted into the inner side of the guide groove 38, and the second guide rod 33 is slidably connected to the guide groove 38. The top surface of the linkage rod 29 is fixedly connected with a pressure plate 36. When the linkage rod 29 moves, the second guide rod 33 fixed on the slider 32 slides along the guide groove 38, so that the second guide rod 33 will drive the slider 32 to pull the linkage rod 29 to gradually move downward a certain distance, and the linkage rod 29 will pull the pressure plate 36 to ensure that the pressing direction is accurate. One end of the linkage rod 29 located above the abutment rod 210 is sleeved with a spring four 37, one end of the spring four 37 is fixedly connected to the bottom surface of the pressure plate 36, and the other end of the spring four 37 is fixedly connected to the top surface of the abutment rod 210. When the linkage rod 29 is in place, the spring four 37 is compressed to generate a continuous pressing force to ensure that the stack is stable and not loose. After ensuring that the edges of the three-dimensional porous flow field plate are aligned, the linkage rod 29 pulls the pressure plate 36 to ensure that the aligned three-dimensional porous flow field plate fits better and avoids loosening, ensuring the stability of the three-dimensional porous flow field plate during installation. A sealing plate 310 is provided above the three-dimensional porous flow field plate stack 4. The sealing plate 310, the electrolytic cell base 1 and the inner side of the bottom plate 21 are all penetrated and threaded by screws 39.

The screws 39 are threaded, and the three-point fixing structure can effectively resist vibration and thermal deformation during the electrolysis process.

[0024] The present invention discloses a three-dimensional porous flow field plate electrolytic cell structure. When in use, the electrolytic cell structure is mainly composed of an electrolytic cell base 1, a three-dimensional porous flow field plate stack 4, a control component 2 and a linkage component 3. When the three-dimensional porous flow field plate stack 4 is being installed or replaced, the control component 2 is responsible for the precise alignment of the stack, and the linkage component 3 ensures the stable fixation of the stack. The two work together to achieve the precise positioning and anti-drift function of the stack. The control component 2 is connected to the electrolytic cell base 1 through the bottom plate 21. When the dial 22 is rotated, the dial groove 23 on its surface drives the dial rod 27 to move. The dial rod 27 is fixedly connected to the linkage plate 26, pushing the linkage plate 26 to slide along the guide rod 214. The spring 28 sleeved on the guide rod 214 provides a reset elastic force to ensure smooth transmission. The linkage plate 26 drives the linkage rod 29 to slide in the limit groove 215. The resistance rod 210 fixed on the linkage rod 29 smoothly pushes the three-dimensional porous flow field plate stack 4 to the predetermined position through its curved end face. Since the linkage rod 29 is inserted into the inner side of the limit groove 215 and is slidably connected with the limit groove 215, the limit groove 215 will relatively limit the linkage rod 29, ensuring that the limit groove 215 accurately controls the movement trajectory of the linkage rod 29 and ensures positioning accuracy. The ratchet 24 at the bottom of the dial 22 engages with the pawl 211 on the inner side of the bottom plate 21 and remains locked under the action of spring 213. This design ensures that the dial 22 can only rotate in one direction to prevent it from moving back after positioning. When repositioning is required, the pawl 211 is disengaged from the ratchet 24 by pulling the pull rod 212. At this time, the dial 22 can rotate freely, which is convenient for adjusting the position of the battery stack. In addition, the external resistance rod 210 can reduce the manual alignment of the multi-layer three-dimensional porous flow field plate, ensuring that the edges of the three-dimensional porous flow field plate are more neat during installation, avoiding deviations that affect the subsequent operation of the electrolytic cell.

[0025] A slider 32 is provided in the lifting groove 31 inside the linkage rod 29. The slider 32 is elastically supported by a limiting rod 34 and a spring 35. When the linkage rod 29 moves, the guide rod 23 fixed to the slider 32 slides along the guide groove 38, so that the guide rod 23 drives the slider 32 to pull the linkage rod 29 gradually downward a certain distance, and the linkage rod 29 pulls the pressure plate 36 to ensure the correct clamping direction. A spring 4 37 is provided between the pressure plate 36 and the contact rod 210, forming a double spring clamping structure. When the linkage rod 29 is in place, the spring 4 37 is compressed to generate a continuous clamping force, ensuring that the battery stack is stable and not loose. After ensuring that the edges of the three-dimensional porous flow field plate are aligned, the linkage rod 29 pulls the pressure plate 36 to ensure that the aligned three-dimensional porous flow field plate is more closely fitted to prevent loosening, thereby ensuring the stability of the three-dimensional porous flow field plate during installation.

[0026] After the three-dimensional porous flow field plate stack 4 is positioned and pressed, a sealing plate 310 is installed on the top, and the sealing plate 310, the electrolytic cell base 1 and the bottom plate 21 are firmly connected by screws 39. The screws 39 are threaded, and the three-point fixing structure can effectively resist vibration and thermal deformation during the electrolysis process, ensuring long-term operational stability.
