ABSTRACT:
A composite oxygen electrode/electrolyte structure for a solid state electrochemical device having a porous composite electrode in contact with a dense electrolyte membrane, which electrode includes: (a) a porous structure having interpenetrating 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 electrode structure is relatively simple to manufacture, requiring relatively few steps to infiltrate an electrocatalyst precursor material to obtain an electrode structure which will perform advantageously in a solid oxide fuel cell, has a relatively low internal resistance, and permits the selection of an optimal electronically-conductive material and electrocatalyst.
