Abstract

Strontium titanate (SrTiO₃) has a cubic perovskite-type structure in the wide range of the temperature and is chemically stable from oxidizing to reducing atmospheres. Moreover donor-doped SrTiO₃ oxides have high electric conductivity. In this study, the examination was made on the possibilities of the application of polycrystalline of SrTi _1-yNb_yO₃ and Sr_1-xY _xTiO₃ to the interconnector material of SOFCs. The result of conductivities corresponded to Kroger-Vink diagram of donor-doped SrTiO ₃.
