Titanium Expanded Mesh – Good Corrosion & Oxidation Resistant Ability

Titanium expanded mesh is made of titanium plate or titanium coil. It is cut and stretched by automatic mesh expanders to form a metal mesh with uniform diamond-shaped openings. Titanium expanded mesh is mostly used as a mixed metal oxide electrode base material to increase the surface area so that more catalyst material can be used. In addition, the flow rate through the base material can be adjusted upwards for better ion separation. Due to the uniformly distributed edges across the anode surface, titanium expanded mesh produces excellent results in current density and plating, providing good solution movement, electrolyte transfer, and plating.

Working Principle

Electrolyzers work by breaking water into hydrogen and oxygen through an electrochemical reaction. The process takes place in a PEM electrolyzer, which consists of two basic components: an anode and a cathode, separated by a proton exchange membrane (PEM).

At the anode, water molecules are broken down into oxygen (O2) and positively charged hydrogen ions (H+), which are facilitated by the application of an electric current. The proton exchange membrane allows only protons to pass through, separating them from electrons. In the cathode chamber, these protons migrate through the membrane and combine with oxygen and electrons to form hydrogen (H2).

Titanium expanded mesh then acts as a support structure for the anode, maintaining anode stability and electrical conductivity.
