Graphite felt and carbon cloth are porous carbon-based materials used as electrodes in redox flow batteries and as an alternative gas diffusion layer material in PEM fuel cells. Manufactured from carbon and graphite, these materials offer high electrical conductivity, high chemical purity and strong resistance to the corrosive electrochemical environments found in both flow battery and fuel cell applications.
In flow battery systems, graphite felt serves as the electrode where the redox reaction occurs — its high surface area and porosity providing extensive reaction sites for the electrolyte to contact the conductive carbon structure, while its chemical resistance withstands prolonged exposure to the battery's electrolyte chemistry. In PEM fuel cells, carbon cloth can serve as an alternative to carbon paper GDL material, offering different mechanical flexibility and gas permeability characteristics suited to specific stack designs.
Material is available in different thickness grades to match your specific electrode or GDL requirement, with fast delivery supporting both production manufacturing and research applications. Hydrogenergy supplies graphite felt and carbon cloth for flow battery electrode applications, fuel cell GDL alternatives, and general electrochemical research requiring high-purity, high-conductivity porous carbon materials.
