Pt/C electrocatalysts prepared by different methods were studied for the oxygen reduction reaction in H2/O2 fuel cells. This work analyses the physical and electrochemical characterization of Pt/C prepared by different methods by XRD, TEM, CV and CP. It was found that the electrochemical activity is correlated with the morphology and with the particle size of the catalysts.
