Demonstrates enhanced power density in proton-conducting ceramic cells, suggesting new design strategies for electrocatalysts.
at 550 °C-a 75% reduction compared to the NiO-free counterpart-enabling a 77.1% increase in maximum power density and over 1200 hours of stable single-cell operation. Beyond protonic ceramic cells, this work presents an approach for designing perovskites by leveraging cation migration and surface segregation at the atomic scale, opening more opportunities for a wide range of electrocatalytic applications.
