Titanium expanded mesh is produced from titanium plates or coils, where it undergoes cutting and stretching using automated mesh expanders to form a metal mesh with consistent diamond-shaped openings. This type of mesh is commonly employed as a base material for mixed metal oxide electrodes to augment the surface area, enabling greater utilization of catalyst materials. Moreover, the base material allows for enhanced flow rates, facilitating improved ion separation.

Featuring evenly distributed edges along the anode surface, titanium expanded mesh delivers exceptional results in terms of current density and plating, facilitating efficient solution movement, electrolyte transfer, and plating processes.

How does Titanium Expanded Mesh function in Electrolyzers‌?

Titanium expanded mesh serves as a ‌core electrode and structural backbone‌ in electrolyzers, enabling efficient electrochemical reactions through the following mechanisms:

Electron Conduction & Catalyst Support‌

Acts as a ‌conductive substrate‌ that transfers electrons between the electrolyte/membrane and the catalyst layer, ensuring uniform current distribution and minimizing resistive losses.
Its ‌porous, high-surface-area structure‌ anchors catalysts (e.g., IrO₂, Pt) for hydrogen evolution (HER) or oxygen evolution (OER), enhancing reaction kinetics.

Gas-Liquid Management‌

The ‌open-aperture design‌ facilitates rapid diffusion of reactants (water, CO₂) to the catalyst surface and efficient removal of gas products (H₂, O₂, CO), preventing bubble accumulation and reducing overpotential.
Tunable pore geometries (e.g., diamond, hexagonal) optimize flow paths to balance gas release and electrolyte contact, critical for high-current-density operations.

Membrane Interaction‌

In PEM electrolyzers, the mesh's ‌smooth surface‌ protects the proton-exchange membrane from abrasion while ensuring even compression for consistent catalyst-membrane adhesion.
Uniform pore distribution minimizes localized current spikes ("hotspots"), extending membrane lifespan.

Compatibility with Electrolyzer Types‌

Functions effectively in ‌alkaline‌, ‌PEM‌, and ‌AEM electrolyzers‌ due to its pH resilience and adaptable geometry, supporting diverse configurations (e.g., zero-gap or flow-through designs).

By integrating conductivity, durability, and fluid dynamics optimization, titanium expanded mesh ensures stable, energy-efficient operation across electrolysis applications.
