ROBUST MIXED CONDUCTING MEMBRANE STRUCTURE

摘要

The present invention provides a membrane structure, comprising in said order a first electronically conducting layer, an ionically conducting layer, and a second electronically conducting layer, characterized in that the first and second electronically conducting layers are internally short circuited. The present invention further provides a method of producing the above membrane structure, comprising the steps of : providing a ionically conducting layer; applying at least one layer of electronically conducting material on each side of said ionically conducting layer; sintering the multilayer structure; and impregnating the electronically conducting layers with a catalyst material or catalyst precursor material.
