Using newly introduced AD machine, as well as conventional sputtering and/or PLD, proton conductive thin films were deposited on porous stainless-steel (PSS) substrates. Solid oxide thin films can be deposited directly on the PSS substrates. However, proton conductive electrolyte for SOFC could not be fabricated because of its gas leakage, which suggests further optimization of particle sizes of raw powders is needed to achieve dense electrolyte. In turn, an SOFC cell structure with proton conductive oxide was successfully deposited on Pd coated PSS by PLD. It showed 0.8mW/cm2 at 400 deg.C and 1.5mW/cm2 at 450 deg.C. Though these values are insufficient for the practical uses, we could demonstrate the possibility of SOFCs using PSS.

使用新引入的AD机以及常规的溅射和/或PLD，将质子导电薄膜沉积在多孔不锈钢（PSS）底物上。固体氧化物薄膜可以直接沉积在PSS底物上。但是，由于其气体泄漏，无法制造用于SOFC的质子导电电解质，这表明需要进一步优化原始粉末的颗粒大小以实现致密的电解质。反过来，通过PLD成功地将带有质子氧化物的SOFC细胞结构成功沉积在PD涂层PS上。它在400摄氏度时显示0.8MW/cm2，450摄氏度显示1.5MW/cm2。尽管这些值不足以用于实际用途，但我们可以证明使用PSS的SOFC的可能性。
