1.3×2.6mm Titanium Expanded Mesh Sheet for PEM Electrolysis
1.3×2.6mm titanium expanded mesh sheet for PEM electrolysis is manufactured from high-purity titanium sheet through precision slitting and stretching technology, creating a uniform micro-diamond mesh structure with excellent conductivity and mechanical stability. The fine 1.3×2.6mm opening design provides efficient gas release, optimized electrolyte circulation, and stable current distribution in PEM electrolysis systems.
Titanium expanded mesh is widely used in hydrogen production and electrochemical industries due to its outstanding corrosion resistance, lightweight structure, and long operational life. Its high open area and durable performance make it an ideal material for PEM electrolyzer electrodes, current collectors, and anode support components.

Titanium's ability to form a stable, self-healing oxide layer ensures the mesh remains inert in aggressive electrochemical environments. It is highly resistant to pitting and stress corrosion, making it the ideal substrate for long-cycle-life batteries and fuel cells operating under harsh conditions.
The 1.3mm (SWD) × 2.6mm (LWD) aperture is meticulously calibrated to provide a high Specific Surface Area. This maximizes contact points for catalysts or active battery pastes, ensuring uniform current distribution and reducing the risk of localized overheating.
As an expanded metal product, this mesh is formed from a single sheet without welds, joints, or weaves. This "one-piece" construction offers superior mechanical rigidity and electrical continuity. At roughly 45% the weight of steel, it is critical for applications where power density and weight reduction are paramount.
The angled strands of the expanded structure promote micro-turbulence, which enhances gas diffusion and prevents bubble accumulation on the electrode surface. This is vital for maintaining high reaction rates in fuel cells and water electrolyzers.
