Development of a Dense Electrolyte Thin Film by the Ink‐Jet Printing Technique for a Porous LSM Substrate

Recently, the fabrication and development of novel solid oxide fuel cell (SOFC) structures were conducted with the aim of enhancing power generation. Newly cathode-supported honeycomb-type SOFC with a promising power/volume ratio is under development. However, the conventional processing techniques used for the fabrication of different SOFC cell components (electrolyte and electrode) are not compatible with the newly constructed honeycomb structure. The ink-jet printing technique may offer the ability to design and fabricate SOFC components on honeycomb substrates and complex 3D structures. In this study, the formation of a dense Gadolinium-doped ceria thin film on a cathode-supported LaSrMnO 3 substrate by the ink-jet printing technique was investigated.
