The quantitative calculation regarding the phase formation and the effect of atmospheric carbon dioxide and humidity on Sr oxide, hydroxide and carbonate segregation on the surface of La0.8¬Sr0.2¬-MnO3 (LSM-20) is calculated using La-Sr-Mn-O-H-C database with respect to the compound energy formalism model by applying CALPHAD approach. The results were compared with the available experimental data under a range of humidification levels, carbon dioxide levels and different temperatures. Based on the quantitative calculation, the most efficient atmospheric condition for this cathode were proposed.
