## Abstract

Advancements in cost-effective and efficient alternative energy sources are critical for socioeconomic development. In this study, Iron-based metal–organic framework (Fe-MOF) electrocatalyst was fabricated using an Fe salt and ligand. Several surface characterization methods, including Fourier Transform-Infrared Spectroscopy (FTIR), Scanning Electron Microscope (SEM), and X-ray diffraction (XRD), were used to characterize the electrocatalyst. Additionally, using Chronoamperometry (CA), Electrochemical Impedance Spectroscopy (EIS), Linear Sweep Voltammetry (LSV), and Cyclic Voltammetry (CV), the electrocatalytic behaviour in a cathodic reaction in PEMFCs is investigated. The study showed the material’s exceptional chemical or surface stability, and great surface morphology of the material that facilitated the cathodic reaction. This study reported the development of a Platinum Group Metal (PGM)-free potential electrocatalyst for oxygen reduction reaction at the cathode in Proton Exchange Membrane Fuel Cells (PEMFCs).
