Membrane Electrode Assemblies Based on Platinum-Cobalt-Ceria Doped Graphene Oxide for PEMFCs Applications

The facile and low-time consuming synthesis of an active and stable catalyst based on graphene materials, with the aim of being used in the oxygen reduction reaction (ORR) represents a major challenge that can significantly contribute to the research dedicated to proton exchange membrane fuel cells (PEMFCs). In this work, we present platinum-cobalt-ceria supported on reduced graphene oxide (Pt-Co-CeO
2
/rGO) as a promising electrocatalyst for ORR that can be obtained by a facile one-step process. The synthesized graphene oxide-based nanocomposite was physico-chemically characterized and evaluated as electrode for oxigen reduction reaction by specific electrochemical methods.
