Chemical stability and cation stoichiometry determine the applicability of LaCrO 3 as a high‐temperature oxide electrode. A model for the behavior of acceptor‐doped LaCrO 3 , as a function of oxygen activity is proposed. The model is in agreement with experimental data on Mg‐doped LaCrO 3 . Stability regimes and compensation mechanisms at various oxygen activities and temperature are presented.
