Carbon fiber paper
Application：
Used as gas diffusion layer in proton exchange membrane fuel cell to support catalyst layer ,stable electrode structure, and provide for the electrode reaction with gas channel, electronic access and drainage channel, etc.
Heating material；
Carbon fiber paper is developed from the base paper which is treated with a series of processing operations, such as resin impregnation, hot pressing, carbonization and graphitization, etc. The base paper is made from carbon fibers and produced with wet-land paper making technology in our company. The carbon fiber paper is one of the four key supporting materials of the proton exchange membrane fuel cell. Its performance is to the level of similar foreign products because of the excellent characteristics, such as good formation of sheet, low resistance, high strength, etc.
