Highly reactive, long-term stable, and low-cost non-noble metal−nitrogen−carbon (M−N−C) catalysts have been widely considered as promising catalysts for the oxygen reduction reaction (ORR) in alkaline anion exchange membrane fuel cells (AEMFCs). However, the slow chemical reaction kinetics and poor stability of these catalysts remain the main challenges for their widespread application. Herein, Mo 2 TiC 2 −NH 4 supports are utilized by loading non-noble metal CoCu−N−C as the ORR catalyst for AEMFCs. The half-wave potential of CoCu−N−C/Mo 2 TiC 2 −NH 4 reaches 0.87 V and decreases by only 2 mV after 10 000 cycles. The fuel cell peak power density based on the CoCu−N−C/Mo 2 TiC 2 −NH 4 catalyst is over 500 mW cm −2 .
