  • Patent number: 8617762
    Abstract: A method of processing a ceramic electrolyte suitable for use in a fuel cell is provided. The method comprises situating a ceramic electrolyte layer over an anode layer; and subjecting the ceramic electrolyte layer to a stress prior to operation of the fuel cell, by: exposing the top surface of the electrolyte layer to an oxidizing atmosphere and the bottom surface of the electrolyte layer to a reducing atmosphere; and heating the electrolyte layer. The stress causes a substantial increase in the number of microcracks, or in the average size of the microcracks, or in both the number of the microcracks and their average size. A solid oxide fuel cell comprising a ceramic electrolyte layer processed by the disclosed method is also provided.
