Abstract:The development and commercialization of proton ceramic fuel cells (PCFCs) are greatly limited due to the lack of suitable cathode materials with a highly active oxygen reduction reaction (ORR) and robust operational stability. Herein, a composite cathode SrCo 0.8 Fe 0.15 W 0.05 O 3−δ (SCFW0.05), consisting of the main single-perovskite (SP) phase and minor double-perovskite (DP) phase, is successfully proposed via a small amount (5%) of W dopinginduced phase separation based on SrCo 0.8 Fe 0.2 O 3−δ (SCF).
