Electroless Ni-Cu-P/nano-graphite composite coatings for bipolar plates of proton exchange membrane fuel cells

▸ The 5083 alloy anodized at 10 °C improved the co-deposition and adhesion of electroless Ni-P-Cu composite coating. ▸ Adding the nanographite improved the electrical conductivity and corrosion resistance of the electroless Ni-Cu-P coating. ▸ Electroless Ni-Cu-P composite-coated 5083 aluminum alloy has great potential use as a bipolar plate in PEM fuel cells.
