Abstract

In order to develop SOFC cell performance, many kind of things were investigated. Electrode microstructure is the one of them therefore we focus on electrodes fabrication easily and efficiently. We can fabricate electrodes easily with Pt using DC magnetron sputtering and sintering. However sputtering is difficult to handle and to grow porous electrodes what we require. On the other hand sintering is much easier than sputtering to make porous and adhesive electrodes. So in this paper we deal with sintering and optimize to deposit electrodes conditions by analyzing electrode microstructure with sacnning electron microscopy(SEM) micrograph. Also, we compare electrochemical performance of cells fabricated by sputtering and sintering.
