In this work, the effect of copper, iron and cobalt oxides on electrochemical properties of lithiated NiO cathodes was reported in low temperature solid oxide fuel cell (LT-SOFC) with ceria-carbonate composite electrolyte. The modified lithiated NiO cathodes were characterized by XRD, DC conductivity, SEM and electrochemical measurements. In spite of lower conductivities of modified cathodes, Li-Ni-M (M = Cu, Fe, Co) oxides with the order of Li-Ni-Co oxide > Li-Ni-Fe oxide > Li-Ni-Cu oxide, compared with that without modification, the catalytic activities of all the Li-Ni-M oxides were improved. In particularly, cobalt oxide modification favors both charge transfer and gas diffusion for O-2 reduction reaction as confirmed by AC impedance measurements. SEM micrographs show that grains aggregate with the modification of copper oxide or iron oxide, which may be responsible for the increased gas diffusion resistance. The results indicate that the lithiated NiO modified by cobalt oxide as cathode is an alternative to improve LT-SOFC performance with ceria-carbonate composite electrolyte.
