core
Grain boundaries (GBs) in polycrystalline materials often block charge transport and drive degradation. Using Gd‐doped CeO2 as a model electrolyte used in fuel/electrolysis cells, we developed a core‐shell infiltration method to selectively modify GB chemistry and space charge potential, achieving orders‐of‐magnitude ionic conductivity changes.
