Low cost stable air electrode material for high temperature solid oxide electrolyte electrochemical cells

Patent Kuo, Lewis J. H. [Monroeville, PA]; Singh, Prabhakar [Export, PA]; Ruka, Roswell J [Churchill Boro, PA]; ...

A low cost, lanthanide-substituted, dimensionally and thermally stable, gas permeable, electrically conductive, porous ceramic air electrode composition of lanthanide-substituted doped lanthanum manganite is provided which is used as the cathode in high temperature, solid oxide electrolyte fuel cells and generators. The air electrode composition of this invention has a much lower fabrication cost as a result of using a lower cost lanthanide mixture, either a natural mixture or an unfinished lanthanide concentrate obtained from a natural mixture subjected to incomplete purification, as the raw material in place of part or all of the higher cost individual lanthanum. The mixed lanthanidemore »« less

Supporting electrodes for solid oxide fuel cells and other electrochemical devices

Patent Sprenkle, Vincent L [Richland, WA]; Canfield, Nathan L [Kennewick, WA]; Meinhardt, Kerry [Kennewick, WA]; ...

An electrode supported electrolyte membrane includes an electrode layer 630 facing an electrolyte layer 620. The opposing side of the electrode layer 630 includes a backing layer 640 of a material with a thermal expansion coefficient approximately equal to the thermal expansion coefficient of the electrolyte layer 620. The backing layer 640 is in a two dimensional pattern that covers only a portion of the electrolyte layer 630. An electrochemical cell such as a SOFC is formed by providing a cathode layer 610 on an opposing side of the electrolyte layer 620.
