Abstract
This invention provides a composite material for bipolar plates for fuel cells including cemented by a MPC binder and electrically conductive fillers, and a method of manufacturing the same. The resulting bipolar plate achieves low gas permeability, high electrical conductivity, high flexural strength and good corrosion resistance. The flexural strength and corrosion resistance can further be enhanced by the incorporation of macro-reinforcement and a polymer based surface treatment, respectively.
