The application of an inkjet printing process for fabricating solid oxide fuel cell (SOFC) cathodes was investigated. Stably-dispersed LSCF-GDC inks were prepared by ball milling, and the composition was easily controlled by the preparation process. Fabrication of an LSCF-GDC layer was successfully carried out by depositing dots and the thickness was easily controlled by repeating printing process. A planar SOFC single cell with a double-layered cathode (comprised of a paste painted cathode layer and an inkjet printed interlayer) achieved a maximum power density of 0.71 W/cm(2) at 600 degrees C. This is the preliminary work for fabricating the cathode layer of a SOFC single cell via inkjet printing.
