Import 50-80% Pure Nickel Fiber Felt For Fuel Cell — Buy in wholesale FOB from Supplier in China

The 50-80% pure nickel fiber felt from Baoji Yinggao Metal Materials is a sintered porous metal material produced from micron-sized pure nickel fibres through high-temperature vacuum sintering. The product is engineered for fuel cell gas diffusion layers and electrode components, with porosity in the 50-80% range indicating substantial open volume for gas permeation and electrochemical reaction sites. Operating temperature is rated at 800-1200°C, with operating pressure specifications incomplete in source data. The material is available as circular discs, square sheets, custom shapes, and filter cartridges, with thicknesses typically ranging from 1 mm to 10 mm in commercial trade.

The manufacturing process combines specialised felting of nickel fibres with vacuum sintering at elevated temperature, which bonds contact points between fibres without fully densifying the structure. This yields a three-dimensional porous architecture with high specific surface area, uniform pore size distribution, and interconnected permeability paths. Pure nickel composition provides strong corrosion resistance in alkaline and high-temperature environments relevant to proton exchange membrane (PEM) and solid oxide fuel cell (SOFC) operations. The sintered structure maintains mechanical integrity under compression while offering the electrical conductivity and thermal dissipation properties required for stack assembly. Standard international material equivalency would reference pure nickel grades such as Ni 200 or Ni 201, though the supplier does not specify ASTM or DIN grade conformance.

Primary applications span hydrogen energy systems, fuel cell stacks, clean energy export equipment, and related electrochemical devices where gas diffusion and current collection occur simultaneously. Buyers include fuel cell stack manufacturers, hydrogen electrolyser producers, research institutions developing next-generation energy systems, and industrial gas filtration specialists adapting nickel felt for high-temperature service. The supplier notes global sourcing patterns from China, Japan, and Germany, positioning Baoji Yinggao within this competitive landscape. Trade is typically in rolls or sheets. Buyers should confirm exact porosity, thickness tolerance, and flatness specifications for their stack design, as fuel cell electrode assemblies demand tight dimensional control to prevent gas crossover and ensure uniform current density distribution.

Baoji Yinggao Metal Materials Co., Ltd. is located at 1502, Unit 1, No.A, Building 12, Chuangyi Building, North 195 High-Tech Road, High-Tech Development Zone, Baoji, Shaanxi Province, China, postal code 721013. Baoji is a recognised centre for titanium and non-ferrous metal industries in China, providing regional context for the supplier's material focus. The company holds harbour trust tier classification. Response rate and average response hours both register as zero in available data, indicating no recorded inquiry activity or a data collection gap. Buyers should initiate direct contact to assess responsiveness and technical English capability before relying on this channel exclusively.

The supplier specialises in porous metal materials, specifically nickel fibre felt for fuel cell and filtration applications. No verified information is available regarding year of establishment, employee count, annual production capacity of nickel felt, ISO 9001 or IATF 16949 certification status, named fuel cell OEM clients, or patent holdings. The company address within a commercial building, rather than an industrial park, suggests possible trading or light manufacturing operations alongside potential primary production. Buyers should request factory visit arrangements, equipment lists (noting need for fibre drawing, felting, and vacuum sintering furnaces), and quality control documentation specific to their batch requirements. Shaanxi Province does offer aerospace and defence supply chain infrastructure, which may indirectly support technical workforce availability.
