Iridium-Coated Titanium PTL – Optimized for PEM Electrolysis
Designed for high-performance PEM electrolyzers, our iridium-coated titanium PTLs combine a high-porosity substrate with a binder-free, ultra-uniform iridium catalyst layer. Using a proprietary impaction-assisted spark ablation technique, we deliver coatings that are durable, nano-structured, and scalable. The result is a highly stable electrode platform suitable for both industrial electrolysis and advanced electrochemical research.
