Description:

A porous mixed conductive phase consisting of (Ba,Sr)(Co,Fe)O3-δ (BSCF) was fabricated on a stainless steelzirconia dual-phase oxygen separation membrane by electrophoretic deposition. To suppress the reaction between stainless steel, zirconia, and BSCF, a gadolinium-doped ceria (GDC) buffer layer was inserted. The GDC buffer layer suppressed the formation of zirconate, a reaction product of BSCF and YSZ, and formed a uniform BSCF layer with a thickness of 10 micrometers. This layer showed good correlated adhesion.
