Preparation and characterization of bifunctional graphitized carbon-supported Pt composite electrode for unitized regenerative fuel cell

► The extent of the carbon support graphitization played an important role on the electrochemically, with more graphitic carbons being more electrocatalyst stability. ► The dispersion of graphitic carbon supports is very effective in the presence of montmorillonite. ► Such an electrocatalyst provides a more stable and corrosion-resistant in round-trip operation for the synthesized graphitized carbon supports and exhibits optimized energy conversion efficiency.
