As a leading manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory brings over two decades of expertise in producing high-performance nickel electrode mesh. This Nickel Electrode Mesh 0.5mm Opening 0.2mm Wire is specifically engineered for hydrogen electrolyzer cell stacks, offering superior conductivity and corrosion resistance. Our mesh is crafted from pure nickel, ensuring reliable performance in alkaline water electrolysis environments. With annual export values between US$5 million and US$10 million, we serve global markets including North America, Europe, and Asia, providing consistent quality and customized solutions.
This product features a precise 0.5 mm opening and 0.2 mm wire diameter, optimized for efficient gas bubble release and uniform current distribution in electrolyzer cells. The plain weave structure provides excellent mechanical strength while maintaining low electrical resistance, making it ideal for hydrogen production applications. Each roll is manufactured under strict quality control to ensure dimensional accuracy and surface cleanliness, reducing the need for post-processing.
Key Product Features & Benefits
- High Purity Nickel (99.5%+): Ensures excellent corrosion resistance in alkaline electrolytes, extending service life.
- Optimized Opening Size (0.5mm): Facilitates effective gas (H₂ & O₂) bubble detachment, reducing overpotential and improving efficiency.
- Fine Wire Diameter (0.2mm): Provides a high surface area to volume ratio, enhancing catalytic activity when coated with catalysts.
- Uniform Weave Structure: Guarantees consistent current distribution across the electrode surface, minimizing hot spots.
- Customizable Dimensions: Available in various widths (up to 1.2m) and lengths to fit your cell stack design.
- Low Electrical Resistance: Reduces energy loss during electrolysis, contributing to higher hydrogen yield.

This mesh is widely used as a substrate or electrode in proton exchange membrane (PEM) and alkaline electrolyzers. Its fine wire diameter and large open area allow for efficient electrolyte flow and gas release, while the nickel material withstands the highly corrosive environment of KOH or NaOH solutions. The mesh can be further coated with catalysts (e.g., NiFe, NiMo) to enhance hydrogen evolution reaction (HER) or oxygen evolution reaction (OER) performance.
Application Advantages
- Hydrogen Electrolyzer Cell Stack: Acts as a current collector and support for catalyst layers.
- Battery Electrodes: Suitable for nickel-based batteries (e.g., NiMH, NiCd) as a conductive substrate.
- Filter Media: Can be used for high-temperature gas filtration in chemical processes.
- Electrochemical Sensors: Provides a stable electrode surface for sensing applications.

Frequently Asked Questions (FAQ)
-
Q: What is the purity of the nickel used in this mesh?
A: Our nickel electrode mesh is made from commercially pure nickel with a minimum purity of 99.5%. Higher purity (e.g., 99.9%) is available upon request for specialized applications. -
Q: Can this mesh be used directly in an alkaline electrolyzer without further treatment?
A: Yes, the mesh is supplied clean and degreased. However, for optimal catalytic activity, it is often recommended to apply a catalyst coating (e.g., NiFe or NiMo) to enhance HER/OER performance. -
Q: What are the standard roll dimensions?
A: Standard width is 1000 mm, and length can be customized per order. Typical rolls are 30 meters long, but we can cut to specific sheet sizes as needed. -
Q: Is this mesh compatible with PEM electrolyzers?
A: While primarily designed for alkaline electrolyzers, nickel mesh can be used in PEM systems as a current collector or bipolar plate component, provided it is coated with a corrosion-resistant layer (e.g., gold or platinum). -
Q: How do you ensure the mesh opening size is consistent?
A: We use precision weaving looms and conduct 100% visual inspection plus random sampling with optical measuring tools to guarantee ±0.02 mm tolerance on opening size. -
Q: What is the lead time for bulk orders?
A: For standard specifications, lead time is 15–20 days after order confirmation. Customized orders may require 25–30 days depending on the quantity and complexity. -
Q: Do you offer free samples for testing?
A: Yes, we provide small free samples (e.g., 100×100 mm) for evaluation. The buyer pays for shipping. Contact us to request a sample. -
Q: Can the mesh be cut to non-standard widths?
A: Absolutely. We can slit the mesh to any width between 50 mm and 1200 mm. Custom widths are available with a minimum order quantity.
