Carbon fiber GDL

compositepapersheet

TORAYCA™ carbon paper is a porous C/C composite (a composite material of carbon fiber and carbon) that has been heat-treated at a high temperature. Its excellent features such as high conductivity, high gas permeability, corrosion resistance, and high strength, make this a favorite base material for fuel cell electrodes and other electrode applications. High Conductivity Carbon fiber bonds strongly to carbon, resulting in better electrical conduction. High Gas Permeability Its high porosity (approx. 78%) lets gases flow through the carbon paper smoothly. Smooth Surface Carbon fibers are oriented in the surface direction so the material has a very smooth surface with few irregularities. High Strength The carbon paper is thin, very strong and offers excellent compression characteristics. Corrosion Resistance The carbon paper is made up of carbon that has been heat-treated at a high temperature, so contains minimal impurities and exhibits excellent corrosion resistance.
