Patent number: 5882809Abstract: A single cell unit of a solid oxide fuel cell that is individually fabricated and sintered prior to being connected to adjacent cells to form a solid oxide fuel cell. The single cell unit is comprised of a shaped anode sheet positioned between a flat anode sheet and an anode-electrolyte-cathode (A/E/C) sheet, and a shaped cathode sheet positioned between the A/E/C sheet and a cathode-interconnect-anode (C/I/A) sheet. An alternate embodiment comprises a shaped cathode sheet positioned between an A/E/C sheet and a C/I/A sheet. The shaped sheets form channels for conducting reactant gases. Each single cell unit is individually sintered to form a finished sub-assembly. The finished sub-assemblies are connected in electrical series by interposing connective material between the end surfaces of adjacent cells, whereby individual cells may be inspected for defects and interchanged with non-defective single cell units.Type: GrantFiled: January 2, 1997Date of Patent: March 16, 1999Assignee: U.S. The United States of America as represented by the United States Department of EnergyInventors: Charles C. McPheeters, Dennis W. Dees, Kevin M. Myles

Patent number: 5841627Abstract: A pseudo-capacitor having a high energy storage capacity develops a double layer capacitance as well as a Faradaic or battery-like redox reaction, also referred to as pseudo-capacitance. The Faradaic reaction gives rise to a capacitance much greater than that of the typical ruthenate oxide ultracapacitor which develops only charge separation-based double layer capacitance. The capacitor employs a lead and/or bismuth/ruthenate and/or iridium system having the formula A.sub.2 ?B.sub.2-x Pb.sub.x !O.sub.7-y, where A=Pb, Bi, and B=Ru, Ir, and O<x.ltoreq.1 and O<y<0.5 and limits the amount of ruthenate and/or iridium in the electrodes while increasing the energy storage capacity. The ruthenate can be synthesized at low temperatures (40.degree.-80.degree. C.) to form a compound with a high surface area and high electronic conductivity which, in combination with the increased pseudo-capacitance, affords high energy/power density in the pseudo-capacitor.Type: GrantFiled: June 3, 1997Date of Patent: November 24, 1998Inventors: Jai Prakash, Michael M. Thackeray, Dennis W. Dees, Donald R. Vissers, Kevin M. Myles

Patent number: 5532078Abstract: An electrochemical cell with a positive electrode having an electrochemically active layer of at least one transition metal chloride. A negative electrode of an alkali metal and a compatible electrolyte including an alkali metal salt molten at cell operating temperature is included in the cell. The electrolyte is present at least partially as a corrugated .beta." alumina tube surrounding the negative electrode interior to the positive electrode. The ratio of the volume of liquid electrolyte to the volume of the positive electrode is in the range of from about 0.1 to about 3. A plurality of stacked electrochemical cells is disclosed each having a positive electrode, a negative electrode of an alkali metal molten at cell operating temperature, and a compatible electrolyte. The electrolyte is at least partially present as a corrugated .beta." alumina sheet separating the negative electrode and interior to the positive electrodes.Type: GrantFiled: September 26, 1994Date of Patent: July 2, 1996Assignee: The University of ChicagoInventors: Laszlo I. Redey, Kevin M. Myles, Donald R. Vissers, Jai Prakash

Patent number: 5248566Abstract: A propulsion system for a vehicle having pairs of front and rear wheels and a fuel tank. An electrically driven motor having an output shaft operatively connected to at least one of said pair of wheels is connected to a fuel cell having a positive electrode and a negative electrode separated by an electrolyte for producing dc power to operate the motor. A partial oxidation reformer is connected both to the fuel tank and to the fuel cell receives hydrogen-containing fuel from the fuel tank and water and air and for partially oxidizing and reforming the fuel with water and air in the presence of an oxidizing catalyst and a reforming catalyst to produce a hydrogen-containing gas. The hydrogen-containing gas is sent from the partial oxidation reformer to the fuel cell negative electrode while air is transported to the fuel cell positive electrode to produce dc power for operating the electric motor.Type: GrantFiled: November 25, 1991Date of Patent: September 28, 1993Assignee: The United States of America as represented by the United States Department of EnergyInventors: Romesh Kumar, Shabbir Ahmed, Michael Krumpelt, Kevin M.

Patent number: 5232794Abstract: An electrolyte that operates at temperatures ranging from 600.degree. C. to 800.degree. C. is provided. The electrolyte conducts charge ionically as well as electronically. The ionic conductors include molecular framework structures having planes or channels large enough to transport oxides or hydrated protons and having net-positive or net-negative charges. Representative molecular framework structures include substituted aluminum phosphates, orthosilicates, silicoaluminates, cordierites, apatites, sodalites, and hollandites.Type: GrantFiled: October 17, 1991Date of Patent: August 3, 1993Assignee: The United States of America as represented by the United States Department of EnergyInventors: Michael Krumpelt, Ira D. Bloom, Jose D. Pullockaran, Kevin M. Myles

Patent number: 5225818Abstract: The thin section data display control panel of the present invention includes a graphic overlay, a diffuser block affixed to the graphic overlay and light emitting diodes surface mounted on a printed circuit board for providing localized sources of light to be transmitted through the diffuser block to the overlay. The graphic overlay is generally opaque, but has translucent areas through which the illumination shines. An overlay reflective portion on a diffuser side of the overlay reflects light back into the diffuser, except in areas adjacent to the translucent areas of the overlay. The diffuser block is affixed to the graphic overlay and is generally transparent for transmitting the light from the light emitting diodes. Block reflective surfaces on the perimeter edges of the diffuser block prevent light from exiting through the edges. Matte surfaces of the diffuser block adjacent the graphic overlay and adjacent the printed circuit board scatter the light transmitted from the light emitting diodes.Type: GrantFiled: November 26, 1990Date of Patent: July 6, 1993Assignee: Data Entry Products, IncorporatedInventors: Weng-Kai K. Lee, David A. Rivera, Kevin M. Myles, H. Michael Berman, Paula C. Willis

Patent number: 3957532Abstract: A solid compact having a uniform alloy composition of lithium and aluminum is prepared as a negative electrode for an electrochemical cell. Lithium losses during preparation are minimized by dissolving aluminum within a lithium-rich melt at temperatures near the liquidus temperatures. The desired alloy composition is then solidified and fragmented. The fragments are homogenized to a uniform composition by annealing at a temperature near the solidus temperature. After comminuting to fine particles, the alloy material can be blended with powdered electrolyte and pressed into a solid compact having the desired electrode shape. In the preparation of some electrodes, an electrically conductive metal mesh is embedded into the compact as a current collector.Type: GrantFiled: June 20, 1974Date of Patent: May 18, 1976Assignee: The United States of America as represented by the United States Energy Research and Development AdministrationInventors: Jack L.
