Abstract

Porous Fe-Cr-Al alloy was investigated for the support material of solid oxide fuel cells. Interfacial resistance at 700oC in 3% H2O - 97% H2 atmosphere between the porous alloy and Ni coating was stable at around 10 mγcm2. Interfacial resistance at 700oC in air between the porous alloy and LSCF coating was stable at around 20 mγcm2. The surface oxide layer on the Fe-Cr-Al alloy consists of nano-sized γ-Al2O3 columns growing outward in the same direction, containing 4 at.% of Sr, which may contribute electronic conduction. It is expected that the negligible Cr content in the surface oxide layer can solve the Cr contamination problem, generally known in SOFC. We are also developing a cell using the porous Fe-Cr-Al alloy by a co-sintering process.
