PEM hydrogen production consumable gas diffusion layer porous titanium plate

PEM hydrogen production consumable gas diffusion layer porous titanium plate is a new type of porous filter material made of industrial high-purity metal powder (99.4%) through processes such as powder classification, molding, sintering, and mechanical welding. The porosity and filtration accuracy can be adjusted in a wide range. It is widely used in the fields of pharmaceutical industry, water treatment industry, food industry, bioengineering, chemical industry, petrochemical industry, metallurgical industry and gas purification. Prospects for novel filter materials as well as porous gas diffusion distribution materials.

The gas diffusion layer porous titanium plate of the PEM hydrogen production consumable is more used on the electrode plate because of its air permeability and internal irregular air holes. Then it is cooled and formed into a large plate, which can be cut or finely turned into a circle. The required shape and specification can be customized according to the needs, and the precision can also be customized. By controlling the size of the powder particles, the precision aperture can be controlled. The product has a breathable function, the pore size is invisible to the naked eye, and the bubbling, or gas distribution, gas shunting, etc. are performed through the pore size.

Product form: The gas diffusion layer porous titanium plate of the PEM hydrogen production consumable is generally in the form of a sheet, which is divided into a circular plate and a square filter plate. The circular filter plate is generally cut by a lathe. After the edge is finely turned, there is no burr. Bright and smooth, or processed by laser cutting, there will be some slight blackening at the edge, which is a normal phenomenon.

Background technique

The electrolytic cell for hydrogen production by electrolysis of water uses water as raw material, and external voltage is applied to form a complete electrification circuit. The injection of electric energy causes the chemical bonds of water molecules to be cracked, hydrogen atoms and oxygen atoms are reconstructed, and finally hydrogen and oxygen are precipitated. Polymer electrolysis system . The main component of the polymer electrolysis system is the membrane electrode, which integrates the proton exchange membrane and the electrode for hydrogen production by electrolysis, greatly shortens the distance between the two electrodes, and effectively reduces the additional power loss caused by the overpotential of the cathode and anode and other resistances. The proton exchange membrane for hydrogen production by electrolysis of water is one of the core components of the membrane electrode of the electrolyzer. The proton exchange membrane (pem) for hydrogen production by electrolysis of water provides channels for the migration and transport of protons, supports the cathode and anode catalysts, and at the same time blocks the product hydrogen and oxygen , and its performance is closely related to that of the proton exchange membrane for hydrogen production from water electrolysis. However, the currently used electrolytic water hydrogen production proton exchange membrane has a large impedance and weak proton conduction, thereby reducing the performance of the electrolytic water hydrogen production proton exchange membrane.

Product industry application:

Now it is mainly used in water electrolysis to produce hydrogen, which is a new energy pillar for the sunrise industry. The micropore diameter of the porous titanium plate is used to fully react with the medium to produce hydrogen energy. The surface is coated to prevent oxidation and increase the efficiency of hydrogen production. It is currently in the market. Good application in the industry.

Hydrogen energy is a major application, and it also has great applications in petrochemical and pharmaceutical filtration. It has obvious advantages, is strong, and is an indispensable substitute product with great prospects for the industry.

Precautions for product use:

Every kind of filter material will be blocked, so it is very important to choose the pore size. If you choose the right pore size, you will have a good filtration efficiency, and the blocking situation will be alleviated. If the blockage is serious, regular replacement can solve this problem.
