Atomically dispersed Fe–N–C electrocatalysts have shown to be promising oxygen reduction reaction (ORR) catalysts for the PEFC cathode [2]. The ORR (Eq. (1)) on platinum group metal–free (PGM-free) electrocatalysts relies on an abundance of active sites such as FeNx, pyridinic and ...
For example, high-performance electrocatalysts usually demonstrate undesired quick degradation in MEAs. This issue significantly limits the development of PEM fuel cells. Herein, recent progress in understanding the degradation of low-PGM and PGM-free catalysts in fuel cell MEAs and materials-based ...
