Mixed ionic-electronic conducting (MIEC) membranes attract the attention because of their high potential for oxygen separation and energy conversion applications. The different fabrication methods of asymmetric membranes consisting of a thin MIEC layer on porous support were developed. The basically dense but not completely hermetic thin layers were achieved. To overcome this problem, we suggest a new concept of bilayer MIEC-Redox membrane. This solid/liquid composite membrane consists of a gastight MIEC thin external layer and a thick internal layer in which the redox reactions and oxygen bubbling occur. Here, we report the transport properties of a copper oxide-based MIEC-Redox membrane.
混合离子电子导体（MIEC）膜因其在氧气分离和能量转换应用方面的巨大潜力而受到关注。已经开发出了由多孔支撑体上的薄 MIEC 层组成的不对称膜的不同制造方法。实现了基本上致密但并非完全密封的薄层。为了克服这个问题，我们提出了一种双层 MIEC-氧化还原膜的新概念。这种固/液复合膜由一个密封的 MIEC 薄外部层和一个内部厚层组成，其中发生氧化还原反应和氧气鼓泡。在这里，我们报告了一种基于氧化铜的 MIEC-氧化还原膜的传输性能。
