Summary, etc. Primarily, oxygen reduction reaction (ORR) kinetics at fuel cell cathode is slower on pure platinum due to its low activity in acidic medium. Owing to the excellent electrocatalytic property of Pt-Co/C nanoparticles for the oxygen reduction reactions (ORR) in fuel cell cathodes, a cubical phase face-centered cubic (FCC) Pt-Co/C electrocatalyst has been synthesized via solvothermal method using water as solvent. Various characterization techniques, such as X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and Energy Dispersive X-ray spectroscopy (EDX) have been carried out for determining the crystallinity, surface morphology, particles size and elemental composition of Pt-Co/C electrocatalyst alloy, respectively. The XRD, EDX and TEM confirm the presence of well faceted FCC Pt-Co/C electrocatalyst with uniform distribution of these nano-size particles with atomic ratio of 3:1. The electrocatalytic activity of synthesized Pt-Co/C electrocatalyst for ORR was investigated by Cyclic Voltammetry (CV) test in acidic medium using HClO<sub>4</sub>. Further, as CV stop crossing is increased, the activity of Pt-Co/C electrocatalyst increases due to less activation polarization with appreciable shifting of Pt-Co/C oxygen reduction peak potential towards more positive scale confirming better electrocatalytic property of the synthesized Pt-Co/C electrocatalyst for ORR.
