Description

Technical Field

[0001] The utility model belongs to the technical field of water electrolysis hydrogen production equipment, and particularly relates to an electrolytic cell end plate with a high-efficiency conductive coating. Background Art

[0002] Water electrolysis hydrogen production equipment is a key technology for hydrogen energy preparation, and the electrolytic cell end plate plays an important role in conducting electricity and controlling the flow of electrolyte in the equipment. Existing electrolytic cell end plates often lead to a decrease in electrolysis efficiency due to problems such as poor corrosion resistance, insufficient electrical conductivity, and bubble attachment, and frequent maintenance also increases costs. In addition, the traditional electrode post connection structure is complex, and the installation and disassembly are inconvenient, affecting the maintenance and replacement of the equipment. Therefore, there is an urgent need for a new type of electrolytic cell end plate with excellent electrical conductivity, corrosion resistance, and easy maintenance to solve these problems.

[0003] A common problem in the existing alkaline electrolytic cell end plate (publication number: CN221275907U) during use is as follows:

[0004] 1. Poor corrosion resistance and insufficient electrical conductivity: The existing electrolytic cell end plate materials are easily corroded by the electrolyte under high current density and long-term electrolysis environment, resulting in a decline in the performance of the end plate, a shortened service life, and an increase in the frequency of maintenance and replacement. The electrical conductivity of the traditional end plate is poor, and the current conduction efficiency is low, resulting in low electrolysis efficiency, affecting the hydrogen production rate, increasing energy consumption. Therefore, there is an urgent need for an electrolytic cell end plate with optimized electrical conductivity and corrosion resistance.

[0005] 2. Inconvenient connection of electrode posts: The existing electrode posts usually adopt fixed connection, and the installation and disassembly process is complex, time-consuming and laborious, and it is easy to have problems of poor contact after long-term use, increasing the difficulty of equipment maintenance. Therefore, there is an urgent need for an electrolytic cell end plate that is convenient for installing electrode posts. Summary of the Invention

[0006] The main purpose of the utility model is to provide an electrolytic cell end plate with a high-efficiency conductive coating, which can effectively solve the problems in the background art.

[0007] To achieve the above purpose, the technical solution adopted by the utility model is: an electrolytic cell end plate with a high-efficiency conductive coating, including the main body of the electrolytic cell end plate. Flow guiding bumps are arranged on the upper and lower end faces of the main body of the electrolytic cell end plate. An insulating edge layer is arranged around the main body of the electrolytic cell end plate. A fixing module is arranged around the insulating edge layer. A positive electrode terminal is arranged on the left side of the flow guiding bump, a negative electrode terminal is arranged on the right side of the flow guiding bump, and an electrode post connection module is arranged at the lower ends of the positive electrode terminal and the negative electrode terminal.

[0008] Furthermore, a titanium-based coating is applied to the front and back sides of the main body of the electrolytic cell end plate and the flow guiding bumps.

[0009] Furthermore, threaded holes are provided inside the fixing module.

[0010] Furthermore, threaded holes are provided inside the electrode post connection module.

[0011] Furthermore, the diversion bumps adopt an array structure.

[0012] The utility model has the following beneficial effects:

[0013] 1. By coating the titanium-based coating on the front and back of the main body of the electrolytic cell end plate, its electrical conductivity and corrosion resistance can be enhanced, and the following benefits can be brought: Improving electrical conductivity: The titanium-based coating has good electrical conductivity, which can effectively reduce resistance loss, ensure uniform current distribution on the plate surface, improve electrolysis efficiency, and reduce energy consumption. Enhancing corrosion resistance: The titanium-based material has extremely strong corrosion resistance, especially in an acidic or alkaline electrolyte environment. The coating can prevent the plate from corrosion, extend the service life, and reduce the maintenance frequency. Reducing bubble adhesion: The surface of the titanium-based coating is relatively smooth, which can effectively reduce the adhesion of bubbles on the plate, enable the bubbles to quickly detach, maintain good fluidity of the electrolyte, and improve the reaction efficiency. Extending the service life of the equipment: The titanium-based coating is not only wear-resistant and corrosion-resistant, but also can effectively improve the overall mechanical properties of the plate, thereby extending the service life of the electrolytic cell and reducing the maintenance cost of the equipment.

[0014] 2. By providing threads inside the electrode post connection module, the electrode post can be quickly disassembled for convenient replacement, and the following benefits can be brought: Quick disassembly: The threaded structure enables the electrode post to be conveniently rotated and disassembled, greatly simplifying the operation steps and reducing the installation and disassembly time. Convenient maintenance: When the electrode post needs to be maintained or replaced, the threaded design makes the operation more flexible, avoiding the disassembly difficulties caused by traditional fixed connections and reducing the maintenance difficulty. Improving work efficiency: The threaded connection makes the electrode post easier to be regularly inspected and replaced, reducing the equipment downtime and improving the work efficiency. Ensuring stability: The threaded design can provide a stable connection while ensuring quick disassembly, avoiding the loosening or poor contact of the electrode post during use.
