β¦ Synopsis
Solid oxide fuel cells (SOFCs) supported on porous steel substrates are recently gaining much attention, because fabrication cost of SOFC might be significantly reduced. In this paper high temperature properties of porous stainless steel 316 L for application in SOFCs are evaluated. The 316 L was investigated using thermogravimetric analysis, XRD analysis and electrical measurements of scales formed on steel surface. The YSZ ceramic electrolyte was deposited on the 316 L and interaction of formed interlayer was evaluated. The results show that the 316 L is applicable only for SOFCs operated below 500 β’ C.
