BARRIER COATINGS FOR INTERCONNECTS; RELATED DEVICES, AND METHODS OF FORMING

摘要

A method of preparing a solid oxide fuel cell is described herein, as well as the fuel cell itself. The method comprises forming a cathode layer comprising a strontium composition on a ceramic electrolyte layer; and forming a barrier layer between the cathode layer and an overlying interconnect structure comprising chromium, so as to substantially prevent the formation of strontium chromate.
