As a leading manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Alkaline Water Electrolysis Nickel Screen for Hydrogen Evolution, designed specifically for industrial H2 production. With over two decades of expertise in wire mesh fabrication, we deliver high-performance nickel screens that serve as efficient cathodes in alkaline water electrolyzers. Our screens are engineered to maximize hydrogen evolution reaction (HER) efficiency, reduce energy consumption, and withstand harsh alkaline environments. Trusted by clients across North America, Europe, and Asia, our products are essential for green hydrogen generation plants and large-scale electrolysis systems.
Key Features & Technical Specifications
- High-Purity Nickel Material: Made from pure nickel (≥99.9%) to ensure excellent corrosion resistance and long service life in 30% KOH electrolyte at 80-90°C.
- Optimized Surface Area: Expanded or woven mesh structure provides a large active surface area, enhancing hydrogen bubble detachment and reducing overpotential.
- Customizable Mesh Parameters: Wire diameter from 0.1mm to 0.5mm, aperture size from 0.5mm to 5mm, and sheet dimensions tailored to your electrolyzer stack design.
- Low Hydrogen Evolution Overpotential: Our nickel screen exhibits superior catalytic activity for HER, helping to lower cell voltage and improve overall energy efficiency.
- Mechanical Strength & Durability: Robust construction withstands thermal cycling and mechanical stress during continuous operation.
- Uniform Current Distribution: The mesh structure ensures even electrical field distribution across the electrode surface, minimizing localized hot spots.
- Easy Integration: Available in roll or sheet form, with optional edge reinforcement or bus bar connection for seamless assembly.
- Eco-Friendly Production: Manufactured with energy-efficient processes, supporting your sustainability goals.

Advantages for Your Electrolysis System
- Improved Hydrogen Purity: The uniform mesh structure reduces gas entrapment, leading to higher purity H2 output.
- Energy Savings: Lower overpotential translates to reduced electricity consumption per kilogram of hydrogen produced.
- Longer Maintenance Intervals: Excellent corrosion resistance minimizes degradation, extending electrode lifespan.
- Faster Installation: Pre-cut shapes and ready-to-use configurations save assembly time.
- Global Logistics Support: We ship from major Chinese ports (Tianjin, Qingdao, Shanghai, Foshan) with reliable delivery to worldwide markets.
Alkaline water electrolysis is the most mature technology for large-scale green hydrogen production. Our nickel screen electrodes are specifically designed to meet the rigorous demands of industrial electrolyzers operating at current densities from 2,000 to 6,000 A/m². The combination of high surface area, durable nickel substrate, and customizable geometry enables our clients to achieve optimal performance in their specific reactor designs. Whether you are building a 1 MW pilot plant or a 100 MW hydrogen facility, our screens can be scaled to your requirements.
Frequently Asked Questions (FAQ)
-
Q: What is the typical lifespan of your nickel screen in an alkaline electrolyzer?
A: Under normal operating conditions (30% KOH, 80-90°C, 4,000 A/m²), the screen can last 3-5 years. Actual lifespan depends on maintenance and operating parameters. -
Q: Can you provide screens with a specific wire diameter and mesh size?
A: Yes, we offer full customization. Our production lines can manufacture wire diameters from 0.1mm to 1.0mm and aperture sizes from 0.5mm to 10mm to meet your exact specifications. -
Q: Do you offer any surface activation to improve catalytic performance?
A: Yes, we can provide surface treatments such as acid etching, plasma treatment, or nickel foam coating upon request to enhance HER activity. Please contact us for details. -
Q: How do you ensure the quality of your nickel screens?
A: We have a strict quality control system. Each batch undergoes material composition analysis, dimensional inspection, and surface uniformity testing. We also provide a test report upon shipment. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is 100 square meters. For custom specifications, MOQ may vary; please consult our sales team. -
Q: How do you package the screens for export?
A: Screens are packed in waterproof paper, then in wooden crates or pallets to prevent damage during transit. We also offer vacuum packaging for sensitive surface treatments. -
Q: Can you ship to my country quickly?
A: With our established logistics network, we ship from multiple Chinese ports and deliver to all major markets (North America, Europe, Southeast Asia, etc.) within 15-30 days depending on destination. -
Q: What is the price range for your nickel screen?
A: Pricing depends on material grade, mesh structure, dimensions, quantity, and surface treatment. Please request a quote for an accurate price.
