dc.description.abstract | Electrical and structural properties of bismuth oxide doped scandia- stabilized zirconia (ScSZ) electrolyte for solid oxide fuel cells (SOFCs) have been evaluated by means of XRD, TGA, DTA, and impedance spectroscopy. The amount of Bi2O3 in the ScSZ was varied in the range of 0.25-2.0 mol%. The original ScSZ samples indicated a rhombohedral crystalline structure that in general has lower conductivity than the cubic phase. However, the addition of Bi2O3 to ScSZ electrolyte was found to stabilize the cubic crystalline phase as detected by XRD. Impedance spectroscopy measurements in the temperature range between 350 and 900 degrees C indicated a sharp increase in conductivity for the system containing 2 mol% of Bi2O3 that is attributed to the presence of the cubic phase. In addition, impedance spectroscopy measurements revealed significant decrease of both the grain bulk and grain boundary resistances with respect to the temperature change from 600 to 900 degrees C and concentration of Bi2O3 from 0.5 to 2 mol%. The electrical conductivity at 600 degrees C obtained for 2 mol% Bi2O3 doped ScSZ was 0.18 S cm(-1). (c) 2006 Published by Elsevier B.V. | - |
