[0002] Hydrogen production by electrolyzing water refers to the process in which water molecules are dissociated into oxygen and hydrogen in an electrolytic cell under the action of direct current. Among them, the electrolytic cell is composed of electrode plates, diaphragms, insulating seals, clamping devices and other accessories. The purpose of the electrode plates is to increase the reaction area, reduce the overvoltage, reduce the gas content of the electrolyte, thereby improving the efficiency of the water electrolytic cell, reducing the inter-electrode voltage and reducing the power consumption. Therefore, the production operation of the electrode plates is also a very important link. In order to improve the service life and effect of the electrode plates, etc., manufacturers will also coat some coatings on their surfaces to play a protective role.

[0003] However, the existing electrode plate coating devices are difficult to coat both sides of the electrode plates simultaneously at one time, and the coating efficiency is low; and after the electrode plates are coated, it is necessary to wait for the coatings to dry naturally, and the waiting time is long, which affects the coating work of the next electrode plate and also results in low coating efficiency. Summary of the Utility Model
