Abstract
AbstractDevelopment of cost‐effective and efficient electrocatalysts for the oxygen reduction reaction (ORR) is one of the most important topics in the polymer electrolyte membrane fuel cells (PEMFCs). Herein, we suggested the enhanced electrochemical catalyst with nanoscale platinum anchored on iron (Fe) and nitrogen (N) co‐doped graphene nanoplatelets (Pt/FeN‐GnPs) with low content of Pt. The nanoscale platinum particles are uniformly anchored on the surface of FeN‐GnPs and result in excellent oxygen reduction activity and stability in acidic media. The fascinating interaction between Pt particles and FeN−GnPs substrate contributed to advanced oxygen reduction activity, outstanding cell performance, and remarkable high stability for acidic PEM fuel cells.
