在過去幾年YSZ (Yttria Stabilized Zirconia) 一直是高溫(> 1000 oC)固態氧化物燃料電池(SOFC)電解質的主要材料，而近年來發現CGO(Cerium Gadolinium Oxide)其氧離子導電度在中溫(600 oC ~ 800 oC)時其氧離子導電度優於YSZ，故本研究以CGO作為電解質材料。
本研究主要以刮刀成形法(Tape-casting)，來製備固態氧化物燃料電池的NiO-CGO 的陽極複合材料，靜電噴塗沉積法(Electrostatic spray deposition)製備CGO電解質薄膜於陽極複合材料上。再使用網印法(screen printing) 製作陰極材料Sm0.5Sr0.5CoO3-δ (SSC) 於SOFC 半電池上，而整體SOFC 單電池的架構為CGO-Ni/ CGO/ SSC。
本研究在ESD系統中所探討的參數有：鍍膜沉積溫度、先驅物溶液濃度、先驅物溶液流率。本實驗最佳的CGO電解質層鍍膜參數為溫度350oC、濃度 0.02 M、流率2.1 mL/hr下，電解質厚度約為7-10μm。

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.
