[0002] An electrolytic cell consists of a cell body, an anode, and a cathode, with a diaphragm separating the anode and cathode compartments in most cases. Depending on the electrolyte, it is classified into three categories: aqueous solution electrolytic cells, molten salt electrolytic cells, and non-aqueous solution electrolytic cells. When direct current passes through the electrolytic cell, an oxidation reaction occurs at the interface between the anode and the solution, and a reduction reaction occurs at the interface between the cathode and the solution, producing the desired product. Optimizing the design of the electrolytic cell structure and rationally selecting electrode and diaphragm materials are key to improving current efficiency, reducing cell voltage, and saving energy.

The diaphragm is disposed between the first main electrode plate and the second main electrode plate, the first diffusion layer is disposed between the first main electrode plate and the diaphragm, and the second diffusion layer is disposed between the second main electrode plate and the diaphragm. The alkaline electrolytic cell includes a first pole frame, a second pole frame, and a sealing gasket. The first pole frame is welded to the periphery of the first main electrode plate, and the second pole frame is welded to the periphery of the second main electrode plate. The first pole frame is used to fix and support the first main electrode plate, and the second pole frame is used to fix and support the second main electrode plate.

The diaphragm assembly 14 and the cathode tank 8 are detachable. During installation, the diaphragm assembly 14 is inserted into the assembly groove 9 so that the diaphragm assembly 14 separates the anode tank 5 from the cathode tank 8. After assembly, the proton exchange membrane 15 is located exactly at the through hole 10. When it needs to be removed, the handle 17 is pulled upward to stretch the handle 17 above the groove 16, and then the handle 17 is grasped to lift the entire diaphragm assembly 14 upward. This structure can facilitate users to quickly assemble and replace the diaphragm assembly 14, and the operation is simple.

[0025] Among them, support rods 20 are provided on both sides of the lifting groove 18, and sliders 19 are sleeved on the outer walls of the support rods 20, and both sides of the lower bottom of the handle 17 slide and displace on the support rods 20 through the sliders 19; sliding and lifting on the support rods 20 by the sliders 19 can effectively improve the stability of the sliding process, which is more conducive to the lifting operation; further, the lower bottom size of the handle 17 is larger than the upper opening of the lifting groove 18, and the upper top size of the handle 17 is smaller than the upper opening of the lifting groove 18. Since the bottom size of the handle 17 is larger than the upper opening of the lifting groove 18, during the lifting process, only the upper top of the handle 17 can pass through the upper opening, and the lower bottom is restricted in the lifting groove 18. The lifting and lowering of the handle 17 is restricted by the opening of the lifting groove 18 to prevent the handle 17 from detaching when it is stretched upward.

During the electrolysis process, hydrogen and oxygen gather on both sides of the diaphragm respectively, thereby achieving separation. The gas collection port 3 is connected to the pipeline, and the gas is sent out through the pump body. When it needs to be removed, the handle 17 is pulled upward to stretch the handle 17 above the groove 16, and then the handle 17 is grasped to lift the entire diaphragm assembly 14 upward. Since the bottom size of the handle 17 is larger than the upper opening of the lifting groove 18, during the lifting process, only the upper top of the handle 17 can pass through the upper opening, and the lower bottom is restricted in the lifting groove 18. The lifting and lowering of the handle 17 is restricted by the opening of the lifting groove 18 to prevent the handle 17 from detaching when it is stretched upward;
