Product Overview
Nickel Fiber Felt is a porous metallic material engineered from micron-scale nickel fibers through advanced sintering technology. Its three-dimensional reticulated structure, high porosity (50–90%), and excellent conductivity make it an ideal electrode and gas diffusion layer (GDL) material in hydrogen production by water electrolysis.
In proton exchange membrane (PEM) electrolyzers and alkaline electrolyzers, nickel fiber felt ensures efficient gas evolution, rapid electrolyte penetration, and stable current distribution, directly improving hydrogen generation efficiency and system stability. Compared to traditional nickel mesh or powder sintered plates, nickel fiber felt offers lower polarization resistance, longer lifespan, and superior corrosion resistance, making it a preferred choice for the clean hydrogen energy industry.
Key Features
• Optimized for Water Electrolysis – Ensures efficient hydrogen and oxygen evolution with uniform gas diffusion.
