Inkjet Printing Infiltration of the Doped Ceria Interlayer in Commercial Anode-Supported SOFCs.

Single-step inkjet printing infiltration with doped ceria CeYeO (YDC) and cobalt oxide (CoO) precursor inks was performed in order to modify the properties of the doped ceria interlayer in commercial (50 × 50 × 0.5 mm size) anode-supported SOFCs. The penetration of the inks throughout the LaSrCoFeO porous cathode to the GdCeO (GDC) interlayer was achieved by optimisation of the inks' rheology jetting parameters.
