Problems solved by technology

[0005] (2) The sealing effect of the flat gasket seal is proportional to the sealing width. If the sealing surface width of the electrolytic cell is too large, the weight and volume of the electrolytic cell itself will be greatly increased, and the assembly difficulty and production cost will also be increased.
[0006] (3) The existing PTFE flat gasket used for electrolytic cell sealing has a certain permanent deformation after use and cannot be used again. The price of PTFE material is relatively high, which leads to increased maintenance costs during equipment cleaning and maintenance
[0009] (1) The mastoid main plate increases the surface area of ​​the plate through the concave-convex surface of the mastoid surface and supports the auxiliary plate. However, the increase of the surface area of ​​this structure is limited by the number of mastoids. Too many settings and high density will not only make the production

Abstract

The invention relates to an energy-saving high-pressure water electrolysis hydrogen production tank. The energy-saving high-pressure water electrolysis hydrogen production tank is formed by combining and tensioning an anode end plate assembly, a cathode end plate assembly, a plurality of groups of circular polar plate frame assemblies and a plurality of groups of combined sealing gaskets with sealing lips by using a plurality of screw rods. Accessory polar plates are woven by using pure nickel wires and nickel-plated metal wires to form porous and multilayer combined grid plate structures with certain thickness and strength and are arranged at two sides of a veneer-type main polar plate; and a plurality of hexagonal or quadrangular gas and liquid channels are arranged in the radial and axial directions of each circular accessory polar plate. The accessory polar plates are fastened by using a plurality of stainless steel bolts arranged on the main polar plate. Due to the adoption of the structure, the gas and liquid can be kept smooth in the electrolysis process when the accessory polar plates are in a stressed state, the surface areas of the polar plates can be greatly increased, and the electrolysis efficiency can be increased. The energy-saving high-pressure water electrolysis hydrogen production tank is simple in structure and convenient and reliable in installation. Compared with the prior art, the energy-saving high-pressure water electrolysis hydrogen production tank has the characteristics of low manufacturing cost, energy saving, consumption reduction and the like so as to be an efficient and high-pressure novel water electrolysis hydrogen production tank.
