  • Patent number: 6653009
    Abstract: Solid oxide fuel cells made by coating a slurry of an electrolyte having a limited amount of organic material onto a carrier tape, depositing a one or two layer electrode material on the tape sufficient to support the electrolyte layer, removing the tape, screen printing a second electrode layer on the exposed surface of the electrolyte layer, and firing the layers at a temperature of 1100-1300° C. The resultant fired fuel cell can be mounted on an interconnector comprising a base plate, grooves formed in one face of the base plate, a porous conductive ceramic contact layer between the base plate and an overlying blocking layer of a porous conductive layer to provide electrical contact between the base plate and the blocking layer, or an interconnector having a fired green tape stack having conductive via contacts and air and gas flow channels formed therein. A sealing glass bonds the overlying layers to the base plate.
    Type: Grant

  • Patent number: 6251473
    Abstract: A method for fabrication of solid ceramic thin films in which a porous or dense supporting substrate is spray coated with an oxide powder/solid suspension to form a coated supporting substrate. The coated supporting substrate is then sintered at an elevated temperature to form a solid ceramic thin film on the supporting substrate.
