Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell technology, and in particular to a square hydrogen production electrolytic cell with high-density hydrogen-oxygen flow channels. Background Technology

[0002] A square hydrogen electrolyzer is a device used to produce hydrogen through the electrolysis of water. Its distinctive design feature is its square shape. These electrolyzers are typically made of corrosion-resistant materials, such as titanium alloys or stainless steel, to withstand the chemical corrosion generated during electrolysis. They contain an electrolyte solution, usually an aqueous solution containing a certain concentration of sodium hydroxide or potassium hydroxide. When an electric current passes through the electrolyte solution, water molecules are decomposed into hydrogen and oxygen. Hydrogen is produced on the cathode side of the electrolyzer, while oxygen is produced on the anode side. The square design of the hydrogen electrolyzer gives it high structural strength and stability, enabling it to withstand high operating pressures and temperatures. Furthermore, the square design facilitates installation and maintenance, improving the equipment's reliability and lifespan. In the renewable energy sector, square hydrogen electrolyzers are widely used in hydrogen production, providing clean and efficient energy for fuel cells and hydrogen-powered vehicles.

[0003] The following problems exist: In the current use of electrolytic cells, the integrated electrolytic cells take up a lot of space during transportation and the internal cleaning is quite complicated, which restricts the transportation and cleaning of electrolytic cells and affects the transportation flexibility and cleaning convenience of electrolytic cells.

[0018] (1) By setting the connection structure between the frame and the insert frame, it is convenient for the staff to stack two or more sets of electrolytic cells, which helps to reduce the space occupied during the transfer of electrolytic cells. By setting the reset spring, the insert plate can be pushed. At this time, the two sets of insert plates on the first side plate of the same group can slide in opposite directions. When one end of the outer wall of the insert plate moves to the top of the second side plate, the top cover can be fixed. Using the pull ring, the insert plate can be pulled back into the square hole on the inner wall of the rotating plate. At this time, the top cover can be disassembled, which also makes it convenient for the staff to clean the inside of the electrolytic cell.

The inner wall of the top cover is equipped with a limiting mechanism. When the top cover is placed vertically downward on the box, the limiting mechanism inside the top cover will automatically insert into the box. At this time, the top cover cannot slide, which also improves the sealing of the connection structure between the top cover and the box. Attached Figure Description
