Abstract

The aims of investigations were studies and development of ceramic materials for high temperature solid oxide fuel cells (SOFC). The solid electrolyte in SOFC cells is usually yttria stabilised cubic zirconia (YSZ). The YSZ is good ionic conductor at temperatures around 1000oC, which are working temperatures of today’s SOFCs. The solid electrolyte in SOFC cells is usually yttria stabilised cubic zirconia (YSZ). The next generation of SOFCs will have lower operating temperatures around or under 800oC. For this the materials with higher ionic conductivity for example CeO2 doped with M3+ ions. Electrically conducting oxides are used as SOFC cathode. LaMnO3, LaFeO3 and LaCoO3 perovskites doped with earth alkaline and aluminium ions, were synthesised and characterised. Possible interactions between perovskites and solid electrolyte materials were studied. Partial replacement of B side ions with alumina ions decreased the rate of formation of undesirable La2Zr2O7 pyroclore with high electrical resistivity on the interface between cathode layer and YSZ. LaFeO3 based cathode material is compatible with CeO2 based solid electrolyte.
