Abstract

Palladium (Pd) as one of platinum (Pt) group metals has attracted significant attentions since it has shown good activities for hydrogen reaction (HOR) and oxygen reduction reaction (ORR) in fuel cell application and high solubility and mobility as hydrogen storage material1.
Furthermore, due to considerably cheaper price than Pt, Pd is regarded as a very compatible substitute alternative to Pt once its electrocatalytic performance can be further enhanced in coherence to Pt catalysts. Over the years, extensive researches have been carried out to investigate Pd nano-structure and surface activity on carbon based Pd system, with few studies having focused on polymer
materials like zeolite based Pd electrocatalyst. Hence, this paper contributes towards the study of laboratory made zeolite supported 1.5 wt% Pd nanoparticle structure and its resultant electrochemical performance for fuel cell application by using cyclic voltammetry (CV) and the Extended X-ray Adsorption Fine Structure (EXFAS).
