Abstract
Chemical stability and cation stoichiometry determine the applicability of LaCrO3 and LaMnO3 as high temperature solid oxide fuel cell (SOFC) interconnects and cathodes respectively. Models for the oxidation-reduction behavior of acceptor doped LaCrO3 and acceptor doped LaMnO3 are reviewed. Experimental data are presented which agree with the models and show the regimes of oxygen activities and temperature over which these oxides can be expected to be stable.Keywords
