Abstract

Full densification of the interconnector La0.8Ca0.2Cr0.9Co0.1O3−δ (LCCC) layer is hardly achieved when it is screen-printed and cofired on a pre-sintered NiO-YSZ (yttria-stabilized zirconia, 8YSZ) substrate. In this study, the LCCC precursors with different concentrations and viscosities were prepared and infiltrated into the LCCC-YSZ layer. The phase development process and densification behavior of the LCCC were analyzed, and the optimum conditions for full densification are suggested. Through the research, we propose a method for manufacturing a dense LCCC interconnector layer.
