Abstract:
in this study carbon supported Pt and Pt-Pd were synthesized as oxygen reduction reaction electrocatalysts in polymer electrolyte membrane fuel cells. Pt and Pt -Pd nanoparticles have been synthesized by reduction of metal precursors with NaBH4. characterization an evaluation the electrocatalysts was carried out by XRD and SEM. electrochemical properties was investigeited by cyclic voltammetry, linear sweep voltammetry, chronoamperometry and impedance electrochemical spectroscopy . the results showed the crystallite size of noble electrocatalysts Pt and Pt-Pd were below 10 nm. also electerochemical studies showed Pt-Pd/C electrocatalyst for oxygen reduction reaction has catalytic activity better than Pt/C.
Keywords:
