چکیده انگلیسی
The fabrication of a cathode layer of solid oxide fuel cells by the dispenser printing was investigated and found to be useful in the creation of a thicker ceramic layer using viscous ceramic slurries. The cathode layer prepared from a mixture of La0.6Sr0.4Co0.2Fe0.8O3âδ (LSCF) and Ce0.9Gd0.1O1.95 (GDC) slurry clearly shows an inhomogeneous microstructure which leads to poor cell performance. In order to solve this problem, the size of the LSCF particles was controlled through a milling process. Better cell performance was observed for the cells with controlled microstructure by adjusting the pore former content, the LSCF/GDC ratio, in addition to the particle size control. This process might be useful in the deposition of a thick ceramic layer on a curved substrate such as micro-tubular cell.
