Great advances have been made in developing Fe/N/C catalyst, which is a potential candidate for replacing the low‐platinum group metal catalysts used in proton‐exchange membrane fuel cells. Herein, a highly efficient porous structure catalyst was synthesised by doping glucose into the zeolitic imidazolate framework, which obtained numerous pores after high‐temperature pyrolysis. The porous carbon structure was conducive to improving mass transport and oxygen reduction reaction (ORR) activities. The Glc‐Fe‐ZIF catalyst exhibited an excellent ORR activity with a half‐wave potential ( E 1/2 ) of 0.874 V (RHE) and the maximum power density reached 0.72 W cm −2 in acidic medium.
