Product Overview
IrTa Coated Titanium Anode for PEM Water Electrolysis is a high-performance mixed metal oxide (MMO) titanium electrode specially developed for oxygen evolution reactions in acidic electrolysis environments. The electrode uses high-purity Grade 1 or Grade 2 titanium as the substrate and is coated with iridium oxide and tantalum oxide through advanced thermal decomposition technology.
Compared with traditional graphite electrodes and conventional metal electrodes, the IrTa coated titanium anode offers significantly improved corrosion resistance, dimensional stability, and electrochemical efficiency. It is particularly suitable for Proton Exchange Membrane (PEM) water electrolysis systems where stable oxygen evolution and long service life are critical.
The IrTa coating system is widely recognized for its excellent catalytic activity during oxygen evolution reactions (OER). The tantalum oxide component improves coating stability and durability, while iridium oxide enhances electrocatalytic performance and reduces oxygen evolution overpotential.
As global demand for hydrogen production and green energy systems continues to increase, IrTa Coated Titanium Anode for PEM Water Electrolysis has become an important material in modern electrochemical engineering applications.
