Low-temperature (300oC-600oC) protonic ceramics (PCs) with high proton conductivity have attracted many applications in energy conversion and storage devices such as fuel/electrolysis cells, membrane reactors, ammonia synthesis, carbon dioxide reduction, and large-scale energy storage. However, the practical utilization of these PC energy devices needs to solve the manufacturing challenges. In this work, we developed a new integrated additive manufacturing and laser processing (I-AMLP) technique by combining microextrusion and ultrasonic spray coating-based additive manufacturing and precise and rapid laser processing (sintering, drying, cutting, and polishing). I-AMLP showed the capability of manufacturing PCs with desired complex geometries, crystal structures, and microstructures. We manufactured the PC parts such as pellets, cylinders, cones, films, tubes, half cells, single cells, and stacks with excellent properties and performance. This I-AMLP technique not only demonstrated the potential to bring PC energy devices into practical use but also made it possible for the direct manufacturing of ceramic-based devices. |
