Mechanical and electrical properties of zirconia-based alumina composites as solid electrolyte used in solid oxide fuel cells (SOFC) were examined, in which the alumina addition and its morphology were changed. The bending strength increased with the addition of 0.38 μm alumina up to 30 mol%, then decreased. In this sample the ionic conductivities almost remained constant up to 30 mol%.
