Solid electrolyte for intermediate temperature solid oxide fuel cell (IT-SOFC) is a challenge for material researchers. However, Gd doped ceria (CGO) found to be a promising electrolyte among the other competitive materials. In the present investigation, we report the structural and electrical properties of CGO thin films prepared by spray pyrolysis technique. The process parameters were optimized for synthesizing Ce0.9Gd0.1O1.95 (CGO10) films. Films were characterized by XRD and EDS and are observed to be phase pure. The SEM showed the dense and uniform film growth. The dc conductivity measured is of the order of 0.5S/cm at 623K.
