[0002] Currently, with the rapid development of hydrogen energy, the number of domestic and foreign enterprises producing hydrogen production equipment has increased rapidly. At present, most of the electrolytic cells used for hydrogen production on the market are circular in structure, and a few are square in structure

[0003] Among them, the circular electrolytic cell has obvious advantages in liquid stirring, because the liquid can flow more evenly in the circular electrolytic cell, and the electrodes are also more easily covered by the liquid to achieve the effect of uniform electrolysis. However, the manufacturing difficulty of the circular electrolytic cell is relatively large, and the cost is also higher than that of the square electrolytic cell. The square electrolytic cell has a relatively low manufacturing cost, is easy to manufacture and develop and improve, and because the electrodes can be composed of multiple flat ceramic or metal plates, it can be applied to electrolytic cells of different sizes and shapes. However, the square electrolytic cell is not as stable as the circular electrolytic cell in liquid stirring, and dead corners are likely to appear, which is not conducive to the uniform flow of the liquid. Therefore, there is an urgent need for an "H"-type electrolytic cell end plate to solve the above problems Summary of the Utility Model

[0028] In the above technical solution, the reaction tank 102 of the end plate 1 has the same shape as that of a traditional circular electrolytic cell, enabling the liquid to evenly cover the inside of the reaction tank 102, achieving the effect of uniform electrolysis of the electrodes. The frame body 201 of the electrode plate frame 2 and the convex block 202 cooperate to form an H-shaped structure, making its overall shape a square with a notch, reducing the production process difficulty compared to the circular electrolytic cell with respect to the center of the circle, and facilitating subsequent research and improvement.
