Effect of metal oxides nano structured on Pt catalyst in fuel cell

Proton exchange membrane fuel cells (PEMFCs) have been considered as a promising power technology for applications in portable and stationary. The prohibitive cost of platinum for catalyzing the cathodic oxygen reduction reaction (ORR) has hampered the widespread use of polymer electrolyte fuel cells (PEFCs). In this study, Pt catalyst was precipitated on Vulcan XC- 72R containing 5 wt.% NiO,Feo and using NaBH4 as a reducing agent. XRD and SEM characterizations were carried out to determine the morphology of the catalysts. XRD patterns of sample showed peaks characteristic of Pt/C and metal oxide nanoparticles. Cyclic voltammetry was recorded to evaluate ORR performance.
