Patent number: 11560636Abstract: Methods for forming a metal oxide electrolyte improve ionic conductivity. Some of those methods involve applying a first metal compound to a substrate, converting that metal compound to a metal oxide, applying a different metal compound to the metal oxide, and converting the different metal compound to form a second metal oxide. That substrate may be in nanobar form that conforms to an orientation imparted by a magnetic field or an electric field applied before or during the converting. Electrolytes so formed can be used in solid oxide fuel cells, electrolyzers, and sensors, among other applications.Type: GrantFiled: July 8, 2019Date of Patent: January 24, 2023Assignees: FCET, INC., UT-Battelle, LLCInventors: Leonid V.

Publication number: 20170162896Abstract: Solid oxide cells having electrolytes comprise alternating layers of metal oxides, in some embodiments. Electrodes in ionic communication with the alternating layers of metal oxides allow for enhanced ionic conductivity. Some embodiments provide for harvesting and releasing ions from the electrolyte using bulk ionic conductivity in combination with interfacial ionic conductivity. Certain embodiments provide for a large number of small cells to reduce material costs without sacrificing cell performance. Techniques for manufacturing, electrode-electrolyte interface materials, and geometries for assembling cells for greater electrical power generation are disclosed.Type: ApplicationFiled: February 15, 2017Publication date: June 8, 2017Applicant: FCET, Inc.Inventors: Mikhail Pozvonkov, Mark A.

Patent number: 9670586Abstract: The present invention provides solid oxide fuel cells, solid oxide electrolyzer cells, solid oxide sensors, components of any of the foregoing, and methods of making and using the same. In some embodiments, a solid oxide fuel cell comprises an air electrode (or cathode), a fuel electrode (or anode), an electrolyte interposed between the air electrode and the fuel electrode, and at least one electrode-electrolyte transition layer. Other embodiments provide novel methods of producing nano-scale films and/or surface modifications comprising one or more metal oxides to form ultra-thin (yet fully-dense) electrolyte layers and electrode coatings. Such layers and coatings may provide greater ionic conductivity and increased operating efficiency, which may lead to lower manufacturing costs, less-expensive materials, lower operating temperatures, smaller-sized fuel cells, electrolyzer cells, and sensors, and a greater number of applications.Type: GrantFiled: November 30, 2013Date of Patent: June 6, 2017Assignee: FCET, Inc.Inventors: Mark A.
