A carbon fiber paper manufacturing process and construction has oxidized fiber as raw material needle punched into a construction of 0.1˜20 mm thick, 5˜500 g/m2 oxidized fiber felt of weight, then impregnated in high density epoxy, hot compressed and hardened, then finally carbonization processed at temperature range of 700˜3000° C. to yield porous carbon fiber paper with high resilience, low porosity, and flexure, and low surface resistance to be used as the substrate of porous carbon electrode in fuel battery. |
