Abstract
This study focused on the development of Cu impregnation process, investigation of carbon deposition and performance of (Ni,Cu)-SDC/YSZ/SDC/LSCF single cell in H2 and CH4 fuel. (Ni,Cu)O-SDC/YSZ/SDC could be prepared by dipping NiO-SDC/YSZ/SDC into the Cu(NO3)2∙3H2O aqueous solution and vacuuming with pumping. Ni-SDC/YSZ/SDC/LSCF single cell without Cu impregnation showed the maximum power density of 418.5 mWcm-2 in H2 fuel while it showed 261.0 mAcm-2 in CH4 fuel. (Ni,Cu)-SDC/YSZ/SDC/LSCF with four times Cu impregnation showed 251.2 mAcm-2 in H2 while it showed higher 382.9 mAcm-2 in CH4 fuel.
