In this work, Ni-Pd and Ni-Ir bimetallic nanoparticles were supported on the vulcan carbon (XC-72) [1]. Morphology of nanoparticles by scanning electron microscopy (SEM) and energy despersive spectroscopy (EDX) techniques was investigated. The kinetics and mechanism of the oxygen reduction reaction (ORR) in 0.1M NaoH were analyzed. The electrocatalytic performance of catalysts inks was investigated by cyclic voltametery (CV), AC impedance spectroscopy (EIS) and chronoamperometery methods [2]. According to the electrochemical measurments, the Ni-Pd catalyst indicated the high current density, low onset potential and lowest charge transfer resistance. Therefore, in accordance with the results of eletrochemical measurment, the Ni-Pd catalyst indicates the higher performance than Ni-Ir catalyst.
