The impregnation method has been considered as one of th most successful techniques for the fabrication of highly efficient electrodes for solid oxide fuel and electrolysis ce lls (SOCs) at the lab scale. However, because the impregnation is usu ally performed manually, its irreproducibility remains a major pro blem that can be solved by using controllable techniques, such as in kjet printing. In this paper, lanthanum strontium manganite (LSM)/ytt ria stabilized zirconia (YSZ) air electrodes were prepared by infi ltrating YSZ porous bodies with LSM precursor solution using ink jet printing, followed by annealing at 800°C for 2 hours. XRD ana lysis confirmed the formation of the LSM phase, which was in the form of nanoparticles with size in the 50-70 nm range on the YSZ walls, as revealed by FEG-SEM observations. The effect of printing parameters on the distribution of the impregnated p hase was investigated and is discussed.
