Processing of carbon fiber/ PFA composite material as electrode of Fuel cells and batteries

Abstract

Highly porous Carbon fiber performs have been impregnated with Poly-Furfuryl alcohol (PFA) by insitu catalytic polymerization of FA. The samples are further pyrolyzed at 600 – 2400 ^oC in an inert atmosphere to form carbon-carbon composite.  The samples were further subjected to intensive electrical and mechanical characterization. Higher heat treatments results in graphitization of the matrix phase leading to increased conductivity. This can probably result in samples with good electrode properties for cells and batteries.
