Hebei Ruiyun Wire Mesh Technology Co., Ltd.
Iridium-Plated Foam Titanium is a high-performance porous material designed for hydrogen production, electrolysis, and fuel cells. It features a titanium foam structure coated with high-purity iridium, providing superior corrosion resistance, excellent conductivity, and enhanced catalytic efficiency. This material is widely used in PEM electrolyzers, fuel cells, and advanced electrochemical applications.
We offer customized sizes, pore structures, and iridium loadings to meet specific industrial and research needs. Contact us for more details!
Product Description
Iridium-plated Titanium Foam combines the lightweight, high-porosity structure of Grade 1 Titanium with the exceptional electrocatalytic activity of high-purity Iridium. Specifically engineered for the Oxygen Evolution Reaction (OER), this material serves as a premium Liquid/Gas Diffusion Layer (LGDL) and anode current collector, significantly reducing overpotential and enhancing the efficiency of hydrogen production.

Core Advantages
The high-purity Iridium coating provides a robust protective layer, preventing the titanium substrate from forming a resistive oxide layer (passivation) in the harsh, acidic environments of PEM electrolyzers.
With an optimized Iridium loading (up to 5 mg/cm²), our foam titanium offers a high specific surface area, maximizing the contact between the catalyst and the electrolyte to lower the OER overpotential.
The 70% porosity and controlled pore size (100–500 µm) facilitate efficient bubble release and rapid electrolyte supply, minimizing mass transfer losses even at high current densities.
Using advanced electroplating technology, the Iridium atoms are firmly bonded to the Titanium skeleton, ensuring zero peeling and long-term stability during thousands of hours of operation.
