摘要：
This work examines the reactivity of a potentially promising SOFC cathode material, La0.5Ba0.5CoO3-delta (LBC), under CO2 atmosphere. Through a combination of different techniques - thermogravimetric analysis, ex situ XRD analyses of reacted products, and in situ XRD analysis - the reaction pathway and kinetics for LBC carbonation is investigated. The thermodynamic phase boundary for carbonate formation in the LBC-CO2 system has been generated and fundamental thermodynamic parameters - the standard state enthalpy (Delta H degrees) and the standard state entropy (Delta S degrees) - are determined.
