Nickel Fiber Felt For AEM PTL
- Product Details
🌐 Nickel Fiber Felt for Hydrogen Production
Changzhou DLX Alloy Co., Ltd. offers high-performance Nickel Fiber Felt, specially engineered for applications in hydrogen production, including alkaline electrolysis (AWE) and anion exchange membrane (AEM) water electrolyzers.
🔧 Product Description
Nickel fiber felt is a porous, sintered metal material made of ultra-fine nickel fibers (typically 4–40 μm in diameter). With its excellent electrical conductivity, high porosity, and corrosion resistance, it is ideal for demanding electrochemical and hydrogen-related environments.
⚡ Key Applications
- Catalyst Support Layer in AWE and AEM electrolyzers 
- Gas Diffusion Layer (GDL) / Porous Transport Layer (PTL) 
- Electrode Substrate for sintered nickel electrodes 
- Support & filtering media in hydrogen purification and storage systems 
- Thermal conductive layer for metal hydride hydrogen storage tanks 
🌟 Product Features
- ✅ High porosity (>85%) and open 3D structure 
- ✅ Excellent corrosion resistance in alkaline environments 
- ✅ Stable electrical and thermal conductivity 
- ✅ Compressible and easy to shape or laminate 
- ✅ Suitable for coating with catalytic materials (e.g., Raney Ni, Ir, Ru)
