We demonstrate the first H₂-ambient air high-temperature anion-exchange membrane fuel cell with an ultra-low platinum-group-metal cathode. Spectroscopic and computational analyses reveal electronically modified Pt/Pd–Ag active sites that tune oxygen reduction adsorption energetics, enabling ~51 kW/g_PGM with good stability.</p> 2026-09-30T09:55:04Z Dataset Dataset 10.6084/m9.figshare.29605538.v1 https://figshare.com/articles/dataset/Unlocking_Performance_and_Stability_in_Ambient-Air_Anion_Exchange_Membrane_Fuel_Cells/29605538 CC BY 4.0
