Electrically conductive fleece, useful as electrodes, gas-diffusion layers in fuel cells and in supercondensers, is prepared by carbonization and graphitization of compressed fiber mat

摘要

Electrically conductive fleece (A) is carbonized and/or graphitized and has the following properties: bending strength below 8 Taber; density 0.1-0.5 g/cm3; thickness 80-500 mu m; electrical conductivity 10-300 S/cm in the machine direction and 30-220 S/cm2 normal to this.
