摘要: Abstract This study deals with the synthesis and characterization of V-doped, TiO 2 supported Pt catalyst (Pt/V-TiO ) for oxygen reduction reaction (ORR) its in-situ performance investigation in proton exchange membrane (PEM) fuel cell. Pt/V-TiO nanocomposite is prepared via a facile sol-gel microwave assisted, modified chemical route compared undoped catalyst, Pt/TiO an identical way. The catalysts are employed as cathode PEM cell standard Pt/C catalyst. Their comparative studies conducted physical electrochemical techniques. In-situ show improved ORR catalytic activity to . Furthermore, both more stable than when subjected 6000 voltammetric cycles range 0.2–1.2 V vs hydrogen electrode operating conditions, losing only material potential immense scope further investigation.
