Products Description
Platinum coated titanium felt is a high quality new metal material made from titanium fibers that have been compressed into a flat form and annealed to ensure a smooth,flat surface suitable for use in electrolytic cells.And through the platinum plating process,a felt-like material with tight coverage,high quality and diverse functions is formed,which greatly extends the service life of the titanium fiber.

Product Features
Mainly used in electrolyzer cells and stacks as flow field or diffuser material, especially on the oxygen (anode) side.Since during the electrolysis reaction,carbon is immediately oxidized into carbon dioxide (if the medium is acidic) or carbonate ions (if the medium is alkaline).The electrolyzer hardware therefore cannot use a carbon-based gas diffusion layer (GDL) on the oxygen evolution electrode, which makes it an ideal candidate diffusion medium while also providing electrical contact between the anode catalyst layer and the bipolar plate or current collector on the anode side.
Function of platinum coating
The primary function of a platinum coating is to maintain the conductivity of the substrate itself for demanding applications such as longer service life or pressurized electrolyzer (up to 100 psi) applications.In industrial use,it has been observed that platinum coated titanium felt can be used on the anode side of PEM electrolyzer hardware at such pressure values.The estimated platinum metal loading of this product is approximately 60-80 micrograms per square centimeter of the physical dimensions of the substrate.

Characterization of Platinum Coated Titanium Felt by SEM and EDM
When should platinum coated titanium felt be used?
Untreated titanium felts are not consumed in the electrolysis unit in the same way as carbon based gas diffusion layers (GDLs),and the presence of oxygen does have an effect if the electrolyzer is operated at pressures slightly above ambient pressure (1 bar to 3 bar).Untreated titanium surfaces rapidly form an electrically insulating oxide layer (TiO2) under high O2 pressures,which ultimately affects the efficiency of the entire system.This oxide coating will behave as an electrical insulator,thus increasing the interfacial resistance in the cell and thus reducing the electrochemical performance.
Product application
Water electrolysis anode,carbon dioxide reduction anode current collector,water electrolysis hydrogen production field,PEM electrolyzer diffusion layer,etc.
Efficient Hydrogen Production
Titanium fiber felt porous material sintered titanium felt has good adsorption capacity for water vapor , and can efficiently extract hydrogen from water.
Reusable
Titanium fiber felt porous material sintered titanium felt has good durability and stability and can be reused many times, reducing the cost and waste of resources in the hydrogen production process.
Environmentally Friendly And Sustainable
Compared with traditional hydrogen production methods, hydrogen production by sintering titanium felt with porous materials such as titanium fiber felt can reduce the use of chemicals and waste generation, and is more in line with the requirements of environmentally friendly and sustainable development.
