| 20080217382 | Metal-ceramic composite air braze with ceramic particulate - A method for joining together two or more ceramic and/or metal parts by providing a braze consisting of a mixture of copper oxide, silver, and ceramic particulate. The braze is placed upon the surfaces of the parts, which are then held together for sufficient time and at a sufficient temperature to cause the braze to form a bond between the parts. The addition of the ceramic particulate increases the viscosity of the braze, decreasing squeeze out, decreasing the formation of air pockets, decreases the formation of brittle phases by providing nucleation sites and increases the flexural strength of the joint. | 09-11-2008 |
| 20080305356 | Diffusion barriers in modified air brazes - A method for joining two ceramic parts, or a ceramic part and a metal part, and the joint formed thereby. The method provides two or more parts, a braze consisting of a mixture of copper oxide and silver, a diffusion barrier, and then heats the braze for a time and at a temperature sufficient to form the braze into a bond holding the two or more parts together. The diffusion barrier is an oxidizable metal that forms either a homogeneous component of the braze, a heterogeneous component of the braze, a separate layer bordering the braze, or combinations thereof. The oxidizable metal is selected from the group Al, Mg, Cr, Si, Ni, Co, Mn, Ti, Zr, Hf, Pt, Pd, Au, lanthanides, and combinations thereof. | 12-11-2008 |
| 20090004545 | Solid bonded interconnect system in a lightweight solid oxide fuel cell stack - An interconnect system for connecting adjacent fuel cells in a fuel cell stack. The system comprises five elements: a separator plate to provide an anode gas flow space when joined to a mating cell frame; a first metal interconnect disposed between the separator plate and the anode surface; a nickel oxide paste applied in a pattern over the surface of the anode and adjacent surface of the separator plate which when sintered results in a conductive layer bonded to the anode and to the separator plate; a second metal interconnect disposed between the cathode surface of the cell and the separator plate of the adjacent cell cassette; and a silver-containing paste applied over the surface of the cathode and the separator plate which when sintered results in a conductive layer bonded to the cathode and to the separator plate. | 01-01-2009 |
| 20090016953 | High-Temperature Air Braze Filler Materials And Processes For Preparing And Using Same - High-temperature air braze filler materials composed of various ternary metal alloys are described. Noble metals (M) are added as a ternary constituent to a silver-copper oxide (Ag—CuO | 01-15-2009 |
| 20090264284 | SULFUR-TOLERANT CATALYST SYSTEMS - Methods for improving the sulfur-tolerance of nickel-based catalyst systems, as well as the improved catalyst systems, are disclosed. The methods can include adding praseodymium alone, or in combination with ruthenium and/or cerium, to a nickel-based catalyst system, thereby inhibiting sulfur poisoning of the catalyst system. Improved catalyst systems can have an added amount of praseodymium alone, or in combination with ruthenium and/or cerium, sufficient to inhibit poisoning of the system by sulfur. | 10-22-2009 |
| 20100081035 | OPTIMIZED CELL CONFIGURATIONS FOR STABLE LSCF-BASED SOLID OXIDE FUEL CELLS - Lanthanum strontium cobalt iron oxides (La(1-x)SrxCoyFe1-yO3-f; (LSCF) have excellent power density (>500 mW/cm2 at 750° C.). When covered with a metallization layer, LSCF cathodes have demonstrated increased durability and stability. Other modifications, such as the thickening of the cathode, the preparation of the device by utilizing a firing temperature in a designated range, and the use of a pore former paste having designated characteristics and combinations of these features provide a device with enhanced capabilities. | 04-01-2010 |
| 20100218875 | DIFFUSION BARRIERS IN MODIFIED AIR BRAZES - A method for joining two ceramic parts, or a ceramic part and a metal part, and the joint formed thereby. The method provides two or more parts, a braze consisting of a mixture of copper oxide and silver, a diffusion barrier, and then heats the braze for a time and at a temperature sufficient to form the braze into a bond holding the two or more parts together. The diffusion barrier is an oxidizable metal that forms either a homogeneous component of the braze, a heterogeneous component of the braze, a separate layer bordering the braze, or combinations thereof.

| 20110092361 | Sulfur-Tolerant Catalyst Systems - Methods for improving the sulfur-tolerance of nickel-based catalyst systems, as well as the improved catalyst systems, are disclosed. The methods can include adding praseodymium alone, or in combination with ruthenium and/or cerium, to a nickel-based catalyst system, thereby inhibiting sulfur poisoning of the catalyst system. Improved catalyst systems can have an added amount of praseodymium alone, or in combination with ruthenium and/or cerium, sufficient to inhibit poisoning of the system by sulfur. | 04-21-2011 |
| 20110111299 | LITHIUM ION BATTERIES WITH TITANIA/GRAPHENE ANODES - Lithium ion batteries having an anode comprising at least one graphene layer in electrical communication with titania to form a nanocomposite material, a cathode comprising a lithium olivine structure, and an electrolyte. The graphene layer has a carbon to oxygen ratio of between 15 to 1 and 500 to 1 and a surface area of between 400 and 2630 m | 05-12-2011 |
| 20110159173 | CONDUCTIVE COATING FOR SOLID OXIDE FUEL CELLS - A method of manufacturing an electrically conductive interconnect for a solid oxide fuel cell stack, including the steps of (a) making a metal substrate having a first surface configured for electrical contact with an anode of the solid oxide fuel cell stack and a second surface configured for electrical contact with a cathode of the solid oxide fuel cell stack; (b) depositing a layer comprising metallic cobalt over at least a portion of at least one of the first and second surfaces; and (c) subjecting the metallic cobalt to reducing conditions, thereby causing at least a portion of the metallic cobalt to diffuse into the metal substrate. | 06-30-2011 |
