The Oxygen Reduction Reaction (ORR) is the core technology for electrochemical reaction for Proton Exchange Membrane Fuel Cells (PEMFC). The precious metals electro catalysts are used as an active cathode catalyst due to their oxygen reduction reaction activity at low temperatures. Instead of Precious metals electro catalysts, the catalysts which is being prepared by non-precious materials is much needed. In this paper we easily and successfully synthesis selenium reduced graphene oxide and assisted cobalt acetate nano particles. The prepared samples are analyzed by X- Ray Diffraction analysis XRD, to confirm the presence of selenium, graphene and cobalt by the peaks, further the functional groups are studied by Fourier Transform Infrared analysis - FTIR. The morphology and the structure were identified by the Scanning Electron Microscope. The composition of selenium, graphene and cobalt are determined by the EDAX studies.
