Defect‐Engineered ZIF‐Derived Non‐Pt Cathode Catalyst at 1.5 mg cm−2 Loading for Proton Exchange Membrane Fuel Cells

Abstract: Due to the sluggish kinetics of the oxygen reduction reaction (ORR) by non‐Pt based catalyst, high loading of catalyst is required to achieve satisfactory fuel cell performance, which inevitably leads to the increase of the catalyst layer thickness with serious mass transport resistance. Herein, a defective zeolitic imidazolate framework (ZIF) derived Co/Fe‐N‐C catalyst with small mesopores (2–4 nm) and high density of CoFe atomic active sites are prepared by regulating the Fe dosage and pyrolysis temperature.… Show more
