Abstract:
1. A method of preparing a layered composite electrode/electrolyte structure, comprising: contacting a mixture consisting essentially of particles selected from the group consisting of an electronically-conductive electrode material and a homogeneous mixed ionically electronically-conductive (MIEC) electrode material with a layer comprising an ionically-conductive electrolyte material to form an assembly comprising a layer of the mixture on at least one side of the layer of the electrolyte material; sintering the assembly to form a porous electrode in contact with a gas-tight electrolyte membrane; and infiltrating the sintered assembly with a solution or dispersion of an electrocatalyst precursor, the electrocatalyst precursor comprising at least one transition metal nitrate.
