WebHydration is a key reaction for incorporating protons by filling oxygen vacancies, V O, with hydroxyl groups and activating proton conduction in the perovskite. However, probing the local environment of oxygen vacancies responsible for hydration is challenging because the behavior depends on the temperature and water partial pressure, which ...
