Abstract Scope |
New developments in composite materials are required to further increase electrocatalytic activity and stability for SOFC electrodes. The performance of these composites is dependent upon both the composition and microstructure of the composite, where these characteristics act synergistically endless number of combinational variables. In this work, methods for fabricating novel ceramic (metal-oxide) microstructures using additive manufacturing methods will be discussed to quickly evaluate key processing variables. Alternative methods to deposit layer-by-layer the ceramic materials and sinter the microstructure were investigated. The talk will discuss the layer-by-layer printing methodologies developed, which permit the in situ alterations to chemistry, particle size, and pore size/structure, while also producing layers with a resolution <20 µm. The talk will also discuss laser processing methods used to sinter the high-temperature ceramic layers. The final electrical and mechanical properties of the produced materials will be characterized and related to the resultant microstructure. |
