A simple method for preparing electrodes for proton exchange membrane fuel cell (PEMFC) is proposed, based on the electrodeposition of Platinum on Vulcan XC-72R substare from H2SO4 and Na2SO4 solution with small amount of H2PtCl6. The electrocatalyst support layer was fabricated by applying Vulcan and polytetrafluoroethylene paste (70:30) on carbon paper. charcoal active was added to Vulcan and four electrodes were fabricated with different portion of vulcan/charcoal active to study its result on oxygen reduction reaction. The electrocatalytic activitiy for oxygen reduction reaction (ORR) were determined for the electrode which had no charcoal active and compared with the electrodes with charcoal active addition to the reaction layer. The electrode with no charcoal active addition to reaction layer showed the highest performance among the fabricated electrodes.
