摘要

•Layered LNNCA anode enabled fuel cell operating temperatures down to 370 °C.•Doped Na+ decreased Li+/Ni2+ intermixing to maintain skeleton stability of LNNCA.•Na-doping introduced affluent oxygen vacancies to provide reactive active sites.•The dissociation of adsorbed hydrogen on LNNCA improve HOR activity.
