| Abstract Scope |
Flat tubular fuel cells represent a hybrid of tubular and planar designs, combining the advantages of both while mitigating their individual limitations. This geometry incorporates internal channels within a compact structure featuring two large planar surfaces, maximizing surface area while reducing sealing complexity. However, the primary fabrication methods reported for ceramic flat tubes are dry pressing and mold-based extrusion which are limited by shape limitations and the tendency to retain non-uniform density throughout the structure. Such non-uniformities can lead to poor dimensional control during sintering and may result in crack formation due to internal stresses. Microextrusion-based 3D printing has demonstrated the ability to fabricate complex geometries for protonic ceramic fuel cell (PCFC) materials. Using this approach, we have developed scalable flat tubular supports with tunable microchannels capable of accommodating intricate channel designs. This work explores the challenges and potential of developing flat tube–supported PCFCs. |
