ABSTRACT:
Ceramic laminate structures, particularly laminate structures including stabilized zirconia compositions, as well as electrodes and electrochemical cells including such laminate structures. The stabilized zirconia composition preferably are selected from scandia-stabilized zirconia and yttria-stabilized zirconia. These laminate structures enhance the overall flexural strength of the electrolyte layer while preserving high electrical conductivity. Such laminate structures may be useful in electrochemical fuel cells such as solid oxide fuel cells.
