This product is developed for advanced electrochemical applications, particularly as a gas diffusion layer in fuel cells, microbial fuel cells, supercapacitors, and lithium-air batteries. The W1S1009 carbon cloth from CeTech features a hydrophobic treatment, making it suitable for use with acidic electrolytes in proton exchange membrane and methanol fuel cells. Its conductive and porous structure supports efficient electron transport and gas management, essential for high-performance energy devices. Available in several sheet sizes, this material is also relevant for electronic sensors and experimental setups requiring reliable, durable carbon-based substrates. The hydrophobic property helps prevent water flooding in fuel cell electrodes, contributing to stable operation. As a technical-grade product, it serves researchers developing next-generation energy conversion and storage systems.
