Composite nickel fiber felt co-sinters sintered nickel fiber felt with expanded nickel mesh into one body - felt porosity plus mesh strength and conductivity - for AEM/alkaline electrolyzer electrodes, gas diffusion layers and precision filtration. Structure and basis weight customizable.
Fine nickel fibers are randomly laid and sintered into felt, which is then co-sintered with expanded nickel mesh into a single body. The mesh adds mechanical strength and a low-resistance electron path; the felt adds 3D high porosity for gas and liquid transport. The two layers are metallurgically bonded - no delamination, no fibre shedding.
The composite uses the best of both layers: expanded mesh raises tensile strength and flatness for large-area assembly and clamping, and shortens the electron conduction path; the felt layer, sintered from >=99.5 percent high-purity nickel fiber, offers adjustable porosity of 50-80 percent with interconnected, evenly permeable pores for long service in alkaline electrolysis.
AEM/alkaline electrolyzer electrodes and gas diffusion layers, fuel cell electrode skeletons, alkaline liquid filtration, EMI shielding and catalyst carriers. Sheets, discs and custom shapes available.
All data above are obtained under specific test conditions; the actual solution must be engineered to site conditions. AIFILTECH provides custom design and sizing based on actual gas volume, temperature, dust characteristics and emission limits.
