摘要：
A high performance composite cathode, La0.6Sr0.4Co0.8Fe0.2O3-delta-Gd0.2Ce0.8O1.9 (LSCF-CGO), was synthesised for intermediate temperature solid oxide fuel cell. The effect of CGO incorporation on the electrical properties was studied by electrochemical impedance spectroscopy. The results show that the LSCF-CGO composite cathode shows better electrochemical performance with maximum power densities of 88 mW cm(-2) at 800 degrees C. The improved performance of LSCF-CGO is attributed to the extended triple phase boundary and enhanced oxide ion conductivity.
