The customer is a Middle Eastern green-hydrogen developer building a megawatt-scale alkaline water electrolysis plant. Nickel mesh from the previous supplier had inconsistent openings, affecting current distribution across the electrode. Unremoved burrs damaged electrode coatings during assembly. The customer required consistent openings, burr-free edges and long-term operation in 30%KOH electrolyte.
Case Overview
Jiangsu DZX supplied alkaline electrolyzers for a UAE green-hydrogen project with customized N4 pure nickel expanded electrode mesh. Diamond openings were tailored to electrode drawings, with consistent dimensions for uniform current distribution. Square/round pieces were cut precisely (±0.5mm tolerance) and deburred to protect electrode coatings. The mesh withstands long-term operation in 30%KOH. Samples were delivered in 1-2 weeks and production batches in 3-5 weeks; electrode-stack assembly passed acceptance on the first attempt.
