Abstract Scope Spraying infiltration technique combined with customized solution chemistry has been developed for nanoscale electrode engineering of SOFC, while targeting improved activity and stability concurrently. Atomization of solution by ultrasonic nozzles actualized controlled distribution of infiltration solution over the entire electrode surface, and the machine-guided process enables application of electrocatalysts to precise electrode locations for optimal functionality. High wettability and reduced viscosity promoted penetration of infiltration solution and, eventually, effective deposition of electrocatalysts at the cathode functional layer. Cobaltite perovskite doped with A-site aliovalent cation (Ba or Sr) was used as an electrocatalyst for either LSM or LSCF based composite cathodes. Series of cell tests demonstrated significant improvement in cathode activity and cell lifetime. The improved fuel cell lifespan, cost reduction, and ease of implementation for industry will enable widespread market penetration of SOFCs.
