    PROTECTIVE COATING FOR GRAPHITE ELECTRODES

    PROTECTIVE COATING FOR GRAPHITE ELECTRODES

    • excellent electrical conductivity • abrasion resistance • no negative influence on steel. The aluminium layer of the protective coating melts at a relatively low temperature – at about 600 °C. It thus remains on the graphite surface as a liquid film with a constant thickness, guaranteeing

    Next Generation Bipolar Plates for Automotive PEM Fuel Cells

    Next Generation Bipolar Plates for Automotive PEM Fuel Cells

    The electrical resistance is reduced (and hence conductivity increased) by the application of coating. Laboratory tests have shown the coating itself to have an electrical resistance of 14.50-22.00μ ohm cm against that of graphite of 600-1000μ ohm cm. Parameter Unit Value Thickness of the Coating Specific Electrical Resistivity
