Product Details
Round porous sintered titanium fiber felt platinum-coated titanium felt is a material commonly used in the electrochemical industry, particularly in proton exchange membrane (PEM) water electrolyzers. This type of felt is made by sintering fine titanium fibers to create a porous structure that provides a large surface area for reactions to occur. The porosity allows for efficient gas diffusion and can help in the uniform distribution of reactants and products within the cell.
Significance of platinization process
To understand the significance of platinum-coated sintered titanium felt, it is essential to delve into its composition and manufacturing process. Titanium felt is initially created through a sintering process, which involves compressing titanium fibers under high heat to form a porous and robust structure. This sintered titanium felt exhibits excellent mechanical strength and chemical stability, making it a suitable candidate for use in harsh environments such as those encountered in fuel cells.
The platinization process further enhances the performance of the titanium felt. Platinum, a noble metal, is deposited onto the surface of the sintered titanium felt through various techniques, such as electrochemical deposition or sputtering. This platinum coating not only improves the electrical conductivity of the felt but also enhances its catalytic activity, enabling it to effectively facilitate the electrochemical reactions that occur within the fuel cell.
