Abstract

In this work, the supporting electrolytes for solid oxide fuel cells based on samarium doped cerium oxide Ce0.8Sm0.2O1.95 were fabricated using 3D inkjet printing and layer-by-layer laser treatment followed by thermal sintering. The samples were characterized by scanning electron microscopy, X-ray diffraction analysis and impedance spectroscopy. The Vickers hardness test and three-point bending flexural test were carried out. The developed approach allows for precise control of the layer thickness and microstructure, significantly facilitating the scaling of solid oxide fuel cells production, and reducing the loss of expensive ceramic materials.
