dc.description.abstractThis study reported the activity of catalysts synthesized from platinum and molybdenum alloys in different atomic ratios and used as cathode electrocatalysts in the PEMFC. The structural properties of PtMo/C and Pt/C catalysts were analyzed by XRD analysis. The composition and distribution of these alloys in Vulcan XC-72R Carbon were determined by SEM and EDX techniques. CV studies assessed electrochemical properties such as ORR and ECSA activity. The performance of PEMFC cathodes that supplied pure hydrogen and ox-ygen was examined using polarization curves at different temperatures. Another way to improve the cathodic reaction is to use ozone as a potent oxidizing agent. It was measured that the OCV of the H-2/O-3 PEM fuel cell was 1.60 V, much greater than the open circuit voltage of the traditional H-2/O-2 PEM fuel cell. The PtMo/C catalyst achieved its highest power density of 137 mWcm(-2) at 70 degrees C, 128 mWcm(-2) at 60 degrees C, 101 mWcm-2 at 50 degrees C, and 85 mWcm(-2) at 40 degrees C when exposed to H-2/O-2. As the temperature of the cell was raised, it was seen that the catalyst's catalytic activity increased.
