Enhanced electrical conductivity of doped CeO2 under millimeter-wave irradiation heating
Source abstract
Abstract
Abstract The electrical conductivity of promising candidates for intermediate temperature solid oxide fuel cell (IT-SOFC) electrolyte; 10–25 mol% gadolinium or samarium-doped CeO2 was measured through impedance measurement under millimeter-wave irradiation heating. Conductivity value for all samples was found to be higher when measured under millimeter-wave irradiation heating than that measured under conventional heating. Results from activation energy show that energy for cation-vacancy dissociation was largely affected by millimeter-wave irradiation, where significant reduction was observed, thus improved the conduction process. Possibility of contribution from non-thermal ponderomotive force in conduction process was discussed.
