Abstract

Abstract : Oxygen electroreduction reaction in 0.1 M KOH aqueous solution has been investigated varying the catalyst loading deposited onto glassy carbon electrode. It was found that with increasing the catalyst loading the electrocatalytic activity increased. Comparable current density values obtained for 1.0 mg cm -2 Pt-Vulcan electrode could be achieved for Pt-C(Mo2 C) electrode with approximate loading of 0.3 mg cm -2, indicating that Pt-C(Mo2 C) catalyst has noticably higher activity towards ORR than Pt-Vulcan catalyst.
