Carbon papers were prepared wet-laid process of pitch-coated carbonized glass fibers, and the electrical conductivity of conductive carbon paper was investigated based on the structural and morphology of pitch-coated carbonized glass fibers prepared by different carbonization temperature. The electrical conductivity of the carbon paper which made of pitch-coated carbonized glass fibers was decreased at 900 8C and 1000 8C of carbonization temperature of pitch-coated glass fibers. This is due to the low stacked crystalline structure of pitch-coated glass fibers which is resulting from a basal carbon loss, in situ gasification and pyrolysis of low molecular compounds of coated pitch, at high carbonization temperature.
