Product Description
This pure nickel zigzag flow mesh serves as a durable substrate or current collector in alkaline water electrolyzers. The zigzag geometry creates an optimized flow field that enhances mass transport of KOH electrolyte, minimizes gas accumulation, and improves overall cell performance compared with conventional parallel or simple pin designs. Ideal for zero-gap configurations, it combines excellent electrical conductivity, outstanding alkali corrosion resistance, and customizable dimensions to meet specific electrolyzer stack requirements.
High-Purity Nickel Construction – Made from pure nickel (Ni200 / Ni201 grade or equivalent) for superior electrical conductivity and long-term stability in concentrated KOH (typically 20–40%).
Zigzag Flow Field Design – Engineered zigzag channels promote uniform electrolyte distribution, efficient bubble removal (H₂/O₂), lower pressure drop, and more even current density across the electrode surface.
Excellent Corrosion Resistance – Forms a stable passive oxide layer in alkaline environments, ensuring extended service life under industrial operating temperatures (60–90 °C) and high current densities.
Customizable Specifications – Available in various mesh sizes, wire diameters, thicknesses, opening geometries, and overall dimensions; suitable for woven, expanded, or specialized zigzag configurations.
Enhanced Surface Area & Mechanical Strength – Provides large active surface for electrochemical reactions while maintaining structural integrity under compression in zero-gap stacks.

FAQ
We use high-purity nickel (typically ≥ 99.5%, with options up to 99.9%+) to ensure optimal conductivity and corrosion resistance in alkaline electrolytes.
The zigzag configuration improves electrolyte flow uniformity, accelerates gas bubble detachment, reduces localized overheating, and helps achieve lower cell voltage and higher efficiency compared with conventional parallel or simple expanded mesh designs.
Yes. Mesh number, wire diameter, thickness, overall size, zigzag pattern depth/angle, and surface finishing can all be tailored to your stack design and operating conditions.
Yes. Pure nickel zigzag flow mesh performs well on both sides in alkaline environments. Additional catalyst coatings can be applied depending on the specific reaction requirements (OER or HER).
Yes. Samples and engineering support are available to help match the pure nickel zigzag flow mesh to your alkaline water electrolyzer requirements.
