Features of Expanded Metal Mesh

Crafted from premium pure nickel-titanium alloy, this 3*5mm expanded metal mesh is engineered to perfectly match the rigorous operating demands of PEM electrolyzers, boasting a portfolio of performance and structural advantages. It combines nickel’s superior electrical conductivity and titanium’s exceptional corrosion and oxidation resistance, enabling stable operation in the acidic, high-temperature and high-pressure electrolyte environment of PEM electrolyzers without premature degradation. The precisely designed 35mm pore size achieves optimal mass and gas transfer efficiency—facilitating unimpeded flow of electrolyte and rapid release of hydrogen/oxygen gas generated during electrolysis, while ensuring uniform current distribution across the mesh surface to avoid local overpotential and improve electrolysis efficiency. As an expanded integral structure, the mesh has no welding seams or weak joints, delivering consistent mechanical strength and electrical conductivity; its excellent fatigue and creep resistance allows it to maintain structural integrity under repeated thermal and pressure cycles of PEM electrolyzer systems, ensuring long service life and low maintenance costs. The metal mesh’s customizable structural density and high dimensional stability also enable seamless fitting with PEM electrolyzer electrode assemblies, reducing assembly gaps and contact resistance for enhanced overall system efficiency.

Applications of Expanded Metal Mesh

This pure nickel-titanium expanded metal mesh (3*5mm) is a high-performance core component exclusively optimized for PEM (Proton Exchange Membrane) electrolyzers, the key equipment for green hydrogen production via water electrolysis. It is primarily applied as anode/cathode current collectors and electrode support layers in PEM electrolyzer stack assemblies, where its excellent conductivity and corrosion resistance bridge the membrane electrode assembly (MEA) and bipolar plates, enabling efficient electron transfer and stable electrolyte circulation. It is widely used in small to medium-sized PEM electrolyzer systems for on-site green hydrogen production, such as renewable energy matching projects (solar/wind power coupled hydrogen production), hydrogen refueling station on-site electrolysis equipment, and laboratory hydrogen production setups. Additionally, it serves as a critical component in portable PEM electrolyzer units for outdoor exploration and mobile hydrogen supply, leveraging its structural compactness and environmental adaptability. The mesh is also an ideal choice for R&D and prototype manufacturing of high-efficiency PEM electrolyzer technologies, and for customized electrolyzer systems in industrial hydrogen production, fuel cell hydrogen supply, and new energy storage fields, supporting the scaling and optimization of green hydrogen production equipment.
