Titanium-based PEM electrolyzers are widely utilized in chlor-alkali processes; the core of their refurbishment lies in the corrosion-resistant repair and performance upgrading of key components. Although the term "electrolytic chlorination process" typically refers to the ion-membrane electrolysis method within the chlor-alkali industry —while PEM electrolyzers are more commonly employed for hydrogen production via water electrolysis—the two applications share a commonality in their material usage: titanium. Due to its exceptional corrosion resistance and electrical conductivity, titanium is extensively used in critical components such as anodes, bipolar plates, and gas diffusion layers.
When refurbishing such equipment, the key focus areas include:
Anode Coating Repair: Utilizing a ruthenium-iridium-titanium anode composition, enhanced via gradient coating technology (e.g., a dense surface layer atop a porous base layer) to boost resistance against oxidative corrosion.
Bipolar Plate Treatment: Subjecting etched or stamped titanium bipolar plates to surface nanostructuring treatments, followed by platinum or gold plating to minimize contact resistance and improve both electrical conductivity and durability.
Gas Diffusion Layer Replacement: Employing titanium felt, titanium mesh, or porous sintered titanium materials as the anode GDL to ensure stable mass transport within acidic, high-potential environments.
