  • Abstract    In the past few years, YSZ (Yttria Stabilized Zirconia) had been the dominate electrolyte material of high temperature (> 1000oC) solid oxide fuel cell (SOFC). In recent years, CGO (Cerium Gadolinium Oxide) has been considered that excellent oxygen-ion conductivity compared toYSZ in intermediate temperature (600oC ~ 800oC), therefore, CGO is used as electrolyte material in this study.
       In this study, single solid oxide fuel cells were prepared using Tape casting, ESD(Electrostatic spray deposition) and screen printing methods. Tape casting was employed to fabricate the NiO-CGO anode, ESD method was employed to deposit films as electrolyte on anode and screen
    printing was used to prepare Sm0.5Sr0.5CoO3-δ (SSC) cathodes on half cells. The SOFC single cell was designed with a configuration of CGO-Ni / CGO / SSC.
    In this study, deposition parameters such as deposition temperature, solution flow rate and concentration of precursor solution were varied to figure out their effects for the resultant films. The optimum deposition temperature is 350oC, flow rate is 2.1 ml/hr , concentration of precursor solution is 0.02 M, and the thickness of CGO film is 7-10 μm.
