Abstract
Metal oxides with perovskite or fluorite structure have been widely used for anode, cathode and electrolyte for solid oxide fuel cells (SOFCs). Understanding of defect chemistry occurred at a SOFC component is of great importance because physical properties of these materials depend on their non-stoichiometry. In this context, a real-time monitoring technique to probe oxygen transport phenomena is beneficial to design nextgeneration SOFC materials. In this contribution, we developed a combined system utilizing thermogravimetric analyzer and a 4 probe electrical conductivity measurement, which provides useful information about changes in weight of a material (e.g., Ceria and a perovskite) simultaneously along with its electrical conductivity. Applicability of this newly developed monitoring system for a number of SOFC materials will be discussed.
