| Research Abstract |
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.
