  • Forming an impermeable sintered ceramic electrolyte layer on a metallic foil substrate for solid oxide fuel cell
    Patent number: 7833642
    Abstract: 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.

  • Fuel cells
    Patent number: 6794075
    Abstract: A solid oxide fuel cell, comprising: a ferritic stainless steel substrate including a porous region and a non-porous region bounding the porous region; a ferritic stainless steel bi-polar plate located under one surface of the porous region of the substrate and being sealingly attached to the non-porous region of the substrate about the porous region thereof, a first electrode layer located over the other surface of the porous region of the substrate; an electrolyte layer located over the first electrode layer; and a second electrode layer located over the electrolyte layers.
