Custom High Temperature Pure Nickel Fiber Felt Sheet

Nickel fiber felt: an ideal material for the hydrogen production industry

Nickel fiber felt is a high-performance material made of micron-level pure nickel fiber through a special felting process and ultra-high temperature vacuum sintering process. It has a unique three-dimensional mesh porous structure and has shown outstanding advantages and broad application prospects in the hydrogen production industry.

1. Product Features

• Excellent conductivity: Nickel fiber felt has excellent conductivity, which can effectively improve the current efficiency in the process of hydrogen production by electrolysis of water, reduce energy consumption, and ensure the stability and efficiency of the hydrogen production process.

• High specific surface area and porosity: Its high specific surface area and porosity, usually between 50%-94%, provide sufficient active sites and good gas diffusion channels for the electrolysis reaction, which is conducive to improving the efficiency and yield of hydrogen production by electrolysis of water, and promoting the generation and release of hydrogen.

• Excellent corrosion resistance: Nickel fiber felt performs well in corrosive environments such as strong alkaline electrolytes, can work stably for a long time, and is not easily corroded, thereby extending the service life of hydrogen production equipment and reducing the maintenance cost of equipment.

• Good mechanical strength: It has high tensile strength and flexibility, can withstand various stresses and deformations in the hydrogen production process, maintain the integrity and stability of the structure, and ensure the normal operation of equipment such as electrolyzers.

• High catalytic activity: Nickel fiber felt has good catalytic activity for the electrolysis of water to produce hydrogen, which can reduce the overpotential of the reaction, increase the reaction rate, reduce the energy consumption required for hydrogen production, and improve the performance and economy of the entire hydrogen production system.

• Good processability: It can be processed into products of various shapes and sizes according to the needs of different hydrogen production equipment, such as sheets, plates, tubes, etc., which are convenient for integration and matching with existing hydrogen production systems to meet diverse application requirements.

2. Application in the hydrogen production industry

AEM hydrogen production electrolyzer electrode: Nickel fiber felt is an ideal application material for the anode diffusion layer of anion exchange membrane (AEM) water electrolysis hydrogen production. Its ultrafine fiber and high porosity structure can effectively improve the performance and efficiency of the electrolyzer, reduce the internal resistance of the electrolyzer, and increase the current density, thereby achieving efficient and stable hydrogen production.

Anode diffusion layer of PEM water electrolyzer: In proton exchange membrane (PEM) water electrolysis, nickel fiber felt can be used as anode diffusion layer (GDL). Its good gas diffusion performance and conductivity can promote the generation and release of hydrogen, improve the efficiency and stability of PEM water electrolyzer, and extend its service life.

Alkaline electrolyzer electrode: Compared with traditional nickel mesh and nickel foam electrodes, nickel fiber felt has obvious advantages in thickness, pore size, unit weight, porosity, etc. It can be used as an electrode material for alkaline electrolyzers to improve the performance and efficiency of electrolyzers and reduce the cost of hydrogen production. It is one of the important directions for the development of hydrogen production technology in alkaline electrolyzers in the future.
