FORMING AN IMPERMEABLE SINTERED CERAMIC ELECTROLYTE LAYER ON A METALLIC FOIL SUBSTRATE FOR SOLID OXIDE FUEL CELL

摘要

An impermeable sintered ceramic electrolyte layer of a solid oxide fuel cell is formed by depositing ceramic powder on a substrate using electrophoretic deposition, isostatically pressing that deposited ceramic layer and then heating the compressed ceramic powder layer at temperatures below 1000° C. In preferred embodiments the ceramic thick film fuel cell assembly is formed upon a ferritic stainless steel substrate.
