Nano-sized GDC (gadolinium-doped ceria) particles are introduced into porous LSCF (La0.6Sr0.4Co0.2Fe0.8O3) cathode of solid oxide fuel cells (SOFCs) by infiltration technique and their effect on the electrochemical performance is investigated using impedance spectroscopy and microstructural analysis. It is found that the infiltrated cathodes have higher electrochemical activity than LSCF cathode. From the microstructural analysis it is indicated that the infiltrated GDC particles form triple-phase boundary on the LSCF surface, and this enhances electrochemical activity of the cathode.
