Abstract
In this study, we investigate a method to fabricate high quality lanthanum strontium cobalt ferrite (LSCF) cathodes for solid oxide fuel cells (SOFCs) using a commercial low price inkjet printer. The ink source is synthesized by dissolving the \LSCF\ nanopowder in a water-based solvent with a proper amount of surfactants. Microstructures of the \LSCF\ layer, including porosity and thickness per printing scan cycle, are adjusted by grayscale in the printing image. It is successfully demonstrated that anode-supported \SOFCs\ with optimally printed \LSCF\ cathodes can produce decent power output, i.e., a maximum peak power density of 377
