Solid oxide fuel cell (SOFC) cathode thin layers were fabricated via inkjet printing with a novel water-based lanthanum cobalt strontium ferrite (LSCF) ceramic ink. The prepared inks and thin cathode layers after printing, drying and sintering were characterized by particle size and zeta potential measurements, surface tensiometry, rheometry, X-ray diffraction and scanning electron microscopy. The results show that a fine particle size is obtained by wet grinding, and the average particle size is reduced from a few micronmeters to approximately 100 nm. Water-based LSCF inks with superior rheological properties and dispersion stability were prepared with the nanoparticles. The problem of satellite droplets during printing and uneven distribution of the jetted droplets on the substrate were effectively solved by optimizing the voltage waveforms of printing parameters, thus greatly improving the quality of droplet injection and distribution. Thin cathode layers with a good surface morphology and a porous microstructure suitable for SOFC applications could be prepared by reducing the number of printing layers and extending the printing time interval between layers.
