Product Details

Platinum plated titanium felt is a special material that is mainly used in electrolytic cell single cells and stacks, especially on the oxygen (anode) side. Due to its unique properties, platinum plated titanium felt has become an ideal alternative to traditional carbon-based gas diffusion layers (GDLs).


In electrolytic cells, platinum plated titanium felt plays an important role as a flow field or diffuser material. When the electrolytic cell is working, oxygen is reduced to hydroxide ions (OH-) on the anode side. In this process, the presence of oxygen and voltage causes the carbon-based GDL material to be consumed and converted into carbon dioxide gas. This not only reduces the electrolytic voltage but also leads to rapid consumption of the carbon GDL, which affects the performance of the electrolytic cell. Platinum plated titanium felt can effectively avoid this problem because it is not easily oxidized and can maintain stable conductivity, even under higher pressure.


High porosity and high permeability platinum-plated titanium fiber felt is a unique material that combines the excellent properties of titanium and platinum to offer a superior performance in electrolyzer stacks. The felt is composed of fine titanium fibers that are randomly intertwined, forming a three-dimensional network with a high surface area and porosity. The high porosity enables the felt to have excellent gas diffusion properties, allowing for efficient transport of reactants and products within the electrolyzer.


The titanium fibers are then plated with a thin layer of platinum, which serves as an electrocatalyst to promote the desired chemical reactions. Platinum is an ideal choice for this purpose due to its high chemical stability, excellent electrical conductivity, and outstanding catalytic properties. The use of platinum-plated titanium fiber felt in electrolyzer stacks significantly enhances the overall efficiency and performance of the device.
