Abstract
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 mW cm?2 at 600
