Abstract
The present invention provides solid oxide cells such as fuel cells, electrolyzers, and sensors comprising an electrolyte having an interface between an yttria-stabilized zirconia material and a glass material, in some embodiments. Other embodiments add an interface between a platinum oxide material and the yttria-stabilized zirconia material in the electrolyte. Further embodiments of solid oxide cells have an ion-conducting species such as an ionic liquid or inorganic salt in contact with at least one electrode of the cell. Certain embodiments provide room temperature operation of solid oxide cells.
Claims17
A solid oxide cell comprising:
- a plurality of substantially-planar substrates separated by a plurality of spacer elements;
- each substrate having a first side opposite a second side, and comprising an electrolyte disposed on the first side, the second side, or a combination thereof, a plurality of first electrodes disposed on the substrates in ionic communication with the electrolyte;
- a plurality of second electrodes disposed on the substrates in ionic communication with the electrolyte and electrically isolated from the plurality of first electrodes;
- wherein the plurality of substrates and the plurality of spacer elements define a plurality of first passages in fluid communication with the first electrodes and a plurality of second passages in fluid communication with the second electrodes;
- wherein the electrolyte comprises a first interface between an yttria-stabilized zirconia material and the substrate, and a second interface between a platinum oxide material and the yttria-stabilized zirconia material.
