Enhanced Performance of Proton Exchange Membrane Fuel Cells Using Platinum–Iron Oxide Catalysts Supported on Activated Carbon Spheres
In this study, the electrochemical performance of Fe3O4-supported Pt/C catalysts was evaluated in a Proton exchange membrane fuel cell (PEMFC), with a focus on enhancing oxygen reduction reaction (ORR) kinetics. Fe3O4 nanoparticles reduced catalyst particle sizes and improved structural stability. Among the catalysts tested—Pt-Fe3O4 magnetic nanoparticle (MNP)/C, Pt/ Fe3O4 MNP-C, and Pt/ Fe3O4 activated carbon sphere (ACS)-C—the Pt/ Fe3O4 MNP-C variant achieved the highest power density (215 mW/cm2 at 346 mA/cm2) and displayed superior activity. Analytical techniques such as XRD, SEM–EDX, and TEM confirmed the superior crystallinity and phase purity of the Pt/ Fe3O4-based catalysts. Particle sizes were found to be 3.16 nm, 2.71 nm, and 4.70 nm, respectively, for Pt-Fe3O4 MNP/C, Pt/ Fe3O4 MNP-C, and Pt/Fe3O4 ACS-C. The high ORR activity of Pt/Fe3O4 MNP-C is attributed to the high surface area and conductivity provided by activated carbon spheres, alongside enhanced Pt-Fe3O4 interactions. Mass activities were recorded at 2829, 2307, and 1893 mA/mgPt, with Pt-Fe3O4 MNP/C showing the fastest kinetics and highest efficiency. Pt/ Fe3O4 MNP-C emerges as a promising low-platinum, high-efficiency electrocatalyst for PEMFCs, marking a significant step toward sustainable fuel cell technologies.
期刊介绍：
The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
