Application:
Carbon fiber, carbon cloth, and carbon paper are widely used as GDL(gas diffusion layers) for fuel cells. They are produced at 1600℃ in a continuous high-temperature carbonization furnace. After a long period of high-temperature heat treatment,the nitrogen, hydrogen and oxygen in fibers and polymers are removed except carbon. The fibers are further transformed into a turbostratic graphite structure or graphite structure to obtain a higher carbon content and fiber orientation.
