Nickel Fiber Felt for AEM Electrolyzer | High Porosity Pure Nickel Diffusion Layer

Nickel Fiber Felt is a high-performance porous material manufactured from high-purity nickel metal fibers. Featuring a continuous three-dimensional interconnected structure, this material offers excellent porosity, high surface area, superior conductivity, and outstanding corrosion resistance.

Compared with traditional nickel mesh and nickel foam materials, nickel fiber felt provides lower contact resistance, improved gas-liquid transport efficiency, and higher mechanical strength, making it an ideal diffusion layer material for AEM (Anion Exchange Membrane) electrolyzers and hydrogen production systems.

Due to the strong passivation capability of nickel, a thin protective oxide layer can rapidly form on the surface, allowing the material to resist corrosion from alkaline environments and certain acidic media. Combined with its stable 3D fiber structure, nickel fiber felt is widely used in advanced hydrogen energy, electrolysis, fuel cell, and industrial filtration applications.

Key Features of Nickel Fiber Felt

High Porosity Structure

Nickel fiber felt features a highly porous 3D interconnected network structure with porosity ranging from 50% to 80%, enabling efficient gas and liquid flow while reducing flow resistance.

Excellent Conductivity

The pure nickel material provides excellent electrical conductivity, helping improve current distribution and electrolysis efficiency in AEM electrolyzers.

Superior Corrosion Resistance

Manufactured from high-purity nickel (Ni ≥ 99.00%), the material offers exceptional resistance to alkaline corrosion and chemical attack, making it suitable for harsh operating environments.

Large Specific Surface Area

Compared with nickel mesh and nickel foam, nickel fiber felt has a larger specific surface area, allowing better contact with anion exchange membranes and reducing interface contact resistance.

Strong Mechanical Strength

The continuous fiber structure provides higher mechanical stability and compression resistance, ensuring long-term operational reliability.

Excellent Permeability

Its interconnected pore structure allows superior gas diffusion and liquid transport performance, improving overall system efficiency.

Customizable Specifications

Thickness, porosity, and dimensions can be customized according to different electrolyzer and industrial application requirements.
