Welcome to Anping County Boli Hardware Wiremesh Products Factory, a professional manufacturer established in 1998 with over 25 years of experience in wire mesh production. Our 0.2mm thick nickel electrode mesh with 200 mesh per inch and 800A/m² hydrogen generation efficiency is specifically engineered for high-performance alkaline water electrolysis and other electrochemical applications. This product combines precise mesh geometry with superior nickel conductivity to maximize gas evolution efficiency while minimizing energy loss. As a trusted supplier exporting to global markets including North America, Europe, and Southeast Asia, we ensure consistent quality and reliable performance for your hydrogen production systems.
Our nickel electrode mesh is manufactured from high-purity nickel wire (Ni ≥99.5%) with a thickness of 0.2mm, creating a balanced structure that offers excellent mechanical strength and optimal active surface area. The 200-mesh per inch configuration provides a uniform aperture size of approximately 0.074mm, enabling efficient bubble release and electrolyte circulation. With a rated current density of 800A/m², this mesh is designed to sustain high hydrogen generation rates without significant voltage drop, making it ideal for industrial electrolyzers and research-scale hydrogen production setups.
Key Features & Technical Specifications
- Ultra-thin yet robust: 0.2mm diameter wire ensures high flexibility and easy shaping while maintaining enough rigidity for electrode frames.
- High open area ratio: 200 mesh yields approximately 40-50% open area, allowing effective gas release and reducing overpotential.
- Excellent conductivity: Nickel's electrical resistivity (~6.9×10⁻⁸ Ω·m) ensures low ohmic losses even under high current density.
- Corrosion resistance: Nickel exhibits exceptional stability in alkaline electrolytes (e.g., 30% KOH) at temperatures up to 90°C.
- Customizable dimensions: Available in rolls or sheets, widths from 500mm to 1500mm, lengths up to 50m per roll upon request.
- Consistent mesh geometry: Precision weaving ensures uniform aperture size and wire spacing, critical for reproducible electrolysis performance.

The 800A/m² hydrogen generation efficiency rating means this mesh can achieve a high hydrogen production rate per unit area when used as a cathode or anode in alkaline electrolyzers. The fine 200 mesh structure provides a large electrochemically active surface area, which enhances the reaction kinetics and reduces the overpotential required for hydrogen evolution. Compared to coarse meshes or solid plates, this design offers up to 3-5 times higher effective surface area, directly contributing to improved energy efficiency and lower operating costs.
Advantages for Your Hydrogen Production System
- Enhanced gas bubble management: The open mesh structure allows hydrogen bubbles to detach quickly, minimizing gas blanketing and maintaining low resistance.
- Reduced energy consumption: Lower overpotential means you can achieve the same hydrogen output with less electrical power input, improving overall system efficiency.
- Long service life: Nickel's inherent corrosion resistance, combined with our precise weaving, ensures the mesh maintains its integrity for thousands of operating hours.
- Easy integration: The mesh can be cut, shaped, or welded to fit existing electrode frames, making it a versatile replacement or upgrade option.
- Cost-effective solution: Our mesh offers a balance of performance and price, providing a competitive alternative to coated or precious metal electrodes.

Frequently Asked Questions
-
Q: What is the maximum temperature this mesh can withstand in alkaline electrolyte?
A: The nickel mesh can operate continuously at temperatures up to 100°C in 30% KOH solution. For higher temperatures, please consult with our technical team for customized solutions. -
Q: Can this mesh be used for both cathode and anode in alkaline water electrolysis?
A: Yes, nickel is suitable for both electrodes. For the anode, it may require a surface activation treatment to improve oxygen evolution efficiency; we can provide recommendations or pre-treatment upon request. -
Q: How does the 200 mesh compare to finer meshes like 300 or 400 mesh?
A: 200 mesh offers a good balance of open area and mechanical strength. Finer meshes have higher surface area but may restrict electrolyte flow and bubble release. The 200 mesh is widely used for industrial electrolyzers due to its optimal performance. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 100 square meters for this specification. However, we can accommodate smaller trial orders for new customers; please contact us for details. -
Q: Do you provide samples for testing?
A: Yes, we offer free samples (shipping cost to be covered by the buyer) of A4-size sheets or small pieces. We recommend testing the mesh in your specific electrolyte and conditions before placing a large order. -
Q: Is the mesh supplied with any surface coating?
A: Standard product is supplied clean and degreased. Optional coatings such as nickel-nickel oxide or platinum group metals are available for enhanced catalytic activity; please inquire for custom surface treatments. -
Q: How is the mesh packaged to prevent corrosion during shipping?
A: We use anti-rust paper, plastic film, and wooden crates or pallets for export. The mesh is also oiled lightly if required, but we can provide oil-free packaging for certain applications. -
Q: What certifications do you have for quality control?
A: While we do not hold specific certifications, our internal quality management system follows industry standards for wire mesh. We can provide a mill test certificate for the nickel material and a dimensional inspection report upon request.
