  • Magnesium phosphate cement based bipolar plate composite material
    Patent number: 10418645
    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.
    Type: Grant
    Filed: August 24, 2017
    Date of Patent: September 17, 2019
    Assignee: NANO AND ADVANCED MATERIALS INSTITUTE LIMITED
    Inventors: Zongjin Li, Hongyan Ma, Wenbin Hao
