摘要：A composite oxygen electrode/electrolyte structure for a solid stateelectrochemical device having a porous composite electrode in contact with a denseelectrolyte membrane, which electrode includes: (a) a porous structure havinginterpenetrating networks of an ionically- conductive material and an electronically-conductive material; and (b) an electrocatalyst different from the electronically-conductive material, dispersed within the pores of the porous structure. This electrodestructure is relatively simple to manufacture, requiring relatively few steps to infiltrate anelectrocatalyst precursor material to obtain an electrode structure which will performadvantageously in a solid oxide fuel cell, has a relatively low internal resistance, andpermits the selection of an optimal electronically-conductive material andelectrocatalyst.
