Summary:A highly corrosion resistant and conductive polymer coating for polymer electrolyte membrane fuel cells bipolar plates have been successfully prepared from renewable plant biomass sources. The coating is based on the 5-hydroxymethylfurfural synthesis by-product resin that consists of complex furanic oligomers and polymers. The corrosion resistance and conductivity of coated titanium plates have been studied. As-prepared coated Ti samples are shown 0.083 μA/cm2 and 0.32 μA/cm2 corrosion current in the simulated PEMFCs cathode and anode environment respectively. In addition, the polymer coating are reduced the interfacial contact resistance of bare titanium up to 40 %. The Ti plates coated with by-products of 5-HMF synthesis are shown a great potential application as bipolar plates for PEMFCs.
