8YSZ electrolyte green bodies were prepared by dry pressing or tape casting, and then the surfaces of the 8YSZ electrolyte bodies were modified by printing or imprinting method. The effect of the electrolyte surface patterns on the polarization resistances was investigated. The results show that the polarization resistances of all surface-modified samples are reduced compared to unmodified samples. For the samples modified by printing, the polarization resistance of the samples with grid, stripe and dot pat...
