Highlights•Nb-TiO2 support for anion-exchange membrane fuel cell is developed•Platinum nanoscale catalysts are immobilized•The composite electrode is ionomer free and outperforms commercial Pt/CSummaryAnion-exchange membrane fuel cells represent a promising and scalable approach for hydrogen energy utilization. However, their development is hindered by the weak bonding between metal catalysts and carbon supports, along with challenges in fabricating electronically/ionically conductive electrodes.
