Abstract
The perovskite LaNi0.6Fe0.4O3 has been prepared by the glycine–nitrate route using different amounts of glycine/fuel ratio (G/N = 0.5, 1.0 and 1.5), in order to study the sample preparation influence on the properties in the context of their application as a cathode contact material for solid oxide fuel cells (SOFCs). The obtained materials have been characterized by X-ray diffraction, scanning electron microscopy, dilatometry and electrical conductivity measurements. All the compounds have rhombohedral symmetry and a porous microstructure with fine grain sizes. The sample obtained at the G/N of 1.0 has more suitable conductivity values for application as SOFC contact material.
