Abstract
The molecular simulation technique was performed to investigate the complex dopant effect on the superionic conduction of oxygen ions in the solid electrolyte for the SOFC applications. The oxygen ionic conductivities in the yttria-stabilized zirconia were apparently improved due to the addition of the Sc 2 O 3 dopants. The characteristics of zirconia-based solid electrolytes contained Y 2 O 3 and Sc 2 O 3 with various components were analyzed here. The oxygen ion diffusion mechanism and its ionic conductivity, activation energy, micro-structure of electrolyte were studied for the analyses of the complex dopants effect on the solid electrolyte.
