Abstract

Abstract Fe–N–C catalyst for oxygen reduction reaction (ORR) has been considered as the most promising nonprecious metal catalyst due to its comparable catalytic performance to Pt in proton exchange membrane fuel cells (PEMFCs). The active centers of Fe–pyrrolic N 4 have been proven to be extremely ...
