Direct formic acid fuel cells (DFAFCs) are one of the potential power sources for the rapidly growing requirement of portable devices. Carbon has traditionally been the most common material of choice for DFAFCs electrocatalyst supports. In this study, Bi2O3 was used for support material because of some advantages such as high corrosion resistance and durability. Bi2O3 supported Pt catalyst was prepared by using microwave irradiation technique. The catalyst was characterized by using SEM/EDS, XRD and FTIR analyses. Electrocatalytic activity of Pt/Bi2O3 catalyst for formic acid oxidation was tested with cyclic voltammetry (CV) and chronoamperometry measurements.
