Electrospun Iron–Polyaniline–Polyacrylonitrile Derived Nanofibers as Non–Precious Oxygen Reduction Reaction Catalysts for PEM Fuel Cells

Replacing high cost platinum (Pt) catalysts with alternative non-precious materials for the oxygen reduction reaction (ORR) is highly desirable to reduce the cost of polymer electrolyte membrane fuel cell (PEMFC) systems. Transition metal-nitrogen-carbon complexes (M-N-C) prepared by high temperature heat treatment techniques are the most promising class of non-precious materials with respect to ORR activity and stability. In this work, …
