Abstract

This work examines the reactivity of a potentially promising SOFC cathode material, La_0.5Ba_0.5CoO_3-δ (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 (ΔH°) and the standard state entropy (ΔS°)-are determined.
