Fuel cell grade gasdiffusion layer carbon paper (CP) electrodes are subjected to electrophoresis in N,N’dimethylformamide (DMF) consisting of reduced graphene oxide (rGO). The rGO modified electrodes are compared with CP in a single asymmetric allvanadium redox battery system (employing a double serpentine flow channel for each halfcell). Peak power densities improved by 4 when the rGO deposits were facing the ionexchange membrane (cell performance was poorer when the rGO was facing the flow field). Cycling of the cells showed least degradation of the CP electrodes that were coated with rGO in comparison to pristine samples.
