Ceramic fuel cell, a.k.a. solid oxide fuel cell, has been emerging as a clean energy technology [1–3]. Researchers of the fuel cell community have been reporting promising electrode and electrolyte materials for the fuel cell since many decades. Many researchers reported fabrication of their cells using power-press methods [4,5]. Although this method is good for the small-scale research studies, this method is not suitable for large-scale upscaling of the technology. The current state-of-the-art ceramic fuel cells are manufactured using tape-casting and screen-printing techniques. Other techniques such as pulse laser deposition, spraying techniques, atomic layer deposition, physical and chemical vapor deposition methods, have been reported as well. Recently, the fabrication of ceramic fuel cell fabrication have been reported using ink-jet and 3D printing techniques. These low-cost printing techniques could solve many issues faced by the promising fuel cell technology. In this study, an overview on the trend of the ceramic fuel cell fabrication and their effects on the cell performance and stability will be presented. The key challenges related to the conventional and 3D fabrication will be highlighted in the work.
