Pure Nickel Ni200 Ni201 Expanded Metal Wire Mesh with Extreme Corrosion Resistance and Optimized Gas Diffusion for Hydrogen Fuel Cells

• Exceptional Electrical Conductivity - Ni200/Ni201 alloys are nearly pure nickel (99.0% minimum), ensuring minimal ohmic loss. The one-piece expanded structure provides a continuous path for electrons, which is vital for maintaining high efficiency in current collection within the fuel cell stack.
• Outstanding Alkaline Corrosion Resistance - Nickel is renowned for its stability in caustic environments. It resists corrosion in high-concentration potassium hydroxide (KOH) and other alkaline electrolytes, ensuring long-term structural integrity of anode/cathode support without metal ion contamination risk.
• Optimized Gas Diffusion Architecture - The expanded "diamond" aperture creates a 3D surface that promotes turbulent flow and uniform gas distribution. This geometry facilitates efficient transport of hydrogen and oxygen to the catalyst layer while managing water byproduct removal.
• Thermal & Mechanical Stability - With a high melting point and excellent ductility, Ni201 (the low-carbon version of Ni200) is particularly suited for applications exceeding 315°C, as it prevents intergranular embrittlement. This ensures dimensional stability during thermal cycling of fuel cell operation.

This nickel expanded metal mesh serves as a high-performance core component with versatile industrial applications. It is specially designed for hydrogen fuel cells and water electrolyzers to enable efficient energy conversion, and widely used in renewable energy systems requiring reliable gas diffusion and current collection capabilities.
