The Ba_0.5Sr_0.5Co_0.8Fe_0.2O_3-δ (BSCF)-based multi-layered oxygen separation membrane was fabricated by the sequential electrophoretic deposition (EPD) process. A thin porous/dense bi-layer of BSCF was formed on a thick porous support of BSCF. The porous support prepared by a sacrificial template method using BSCF powder mixed with wheat starch (30 wt%) as a pore-forming agent, followed by uniaxial pressing and low-temperature sintering, was directly used as an EPD electrode. A thin BSCF layer was first formed on the porous support, and then a thin BSCF + PMMA (polymethyl methacrylate) layer was sequentially formed on the thin BSCF layer using a bimodal suspension of BSCF and PMMA. A 30-μm thin porous/dense bi-layer of BSCF of which the total thickness was obtained by optimizing the processes of EPD and subsequent co-sintering. The oxygen separation performance of 3.7 ml (STP) min⁻¹ cm⁻² at 860 °C was achieved for the BSCF-based multi-layered oxygen separation membrane.

Ba _0.5 Sr _0.5 Co _0.8 Fe _0.2 O3 _-δ（BSCF）为基础的多层氧分离膜是通过顺序电泳沉积（EPD）工艺制备的。在BSCF的厚多孔载体上形成BSCF的薄多孔/致密双层。通过牺牲模板法使用BSCF粉末与小麦淀粉（30 wt％）混合作为成孔剂，然后单轴压制和低温烧结制备的多孔载体直接用作EPD电极。首先在多孔载体上形成薄的BSCF层，然后使用BSCF和PMMA的双峰悬浮液在薄的BSCF层上依次形成薄的BSCF + PMMA（聚甲基丙烯酸甲酯）层。30微米的BSCF多孔/致密双层，通过优化EPD和随后的共烧结工艺获得了总厚度。氧分离性能为3。^-1厘米^-2在860℃下对于基于BSCF-多层氧分离膜来实现。
