Fe–N–C Catalysts: Progress in the Development of Fe‐Based PGM‐Free Electrocatalysts for the Oxygen Reduction Reaction (Adv. Mater. 31/2019)

Abstract

Remarkable progress has been accomplished in the past decade in the development of platinum‐group‐metal‐free (PGM‐free) oxygen reduction reaction (ORR) catalysts, a highly attractive alternative to the incumbent precious‐metal‐based catalysts for polymer electrolyte fuel cells. In article number 1806545, Piotr Zelenay and co‐workers review research efforts aimed at obtaining Fe‐based PGM‐free catalysts with high activity and improved long‐term stability, as well as at a better understanding of the nature of ORR active sites – a prerequisite for further successful development of this class of fuel cell materials.
