Abstract
Solid Oxide Fuel Cells (SOFC) are based on electrolytes and mixed ionic and electronic conductivity (MIEC) materials. The need to reduce costs causes an increase in interest of new compounds suitable for operating temperatures between 600 °C and 800 °C. The SrTi1-xFexO3 (STF) perovskite material is a perspective material that could be used for the oxygen electrodes. In this work STF materials with different content of iron (x = 0.35, 0.5 and 0.7) have been evaluated. The paper presents synthesis, sintering properties, paste and layer preparation with preliminary electrical measurements. The results show that the electrical conductivity increases with the addition of iron, whereas the activation energy decreases. Based on these results, the applicability of STF as a potential oxygen electrode was discussed.
