Process And System For Thermally Uniform Materials Processing

US Patent:
2004017, Sep 9, 2004
Filed:
Feb 10, 2004
Appl. No.:
10/775542
Inventors:
Donald Seccombe - Gloucester MA, US
Gary Orbeck - Windham NH, US
International Classification:
H05B006/64
US Classification:
219/762000
Abstract:
The present invention provides a system and method for binder removal and sintering of materials such as ceramic materials and products, LTCC intervals, solid oxide fuel cells and powder metals. A combination of microwave and convection/radiation heating is employed for binder removal and sintering. Preferably, the microwave heating is accomplished using a variable or multi-frequency microwave source. A gas atmosphere is provided in the furnace chamber by one or more eductors which produces a high volume gas circulation in the furnace chamber to achieve a highly uniform gas environment and temperature. The process in accordance with the invention controls the heating cycle, the heat sources and thermal profile depending upon the composition of the particular material being processed. The thermal processing can be accomplished in a batch furnace in which a product is loaded for processing and unloaded after processing. The invention can also be practiced in a continuous process wherein the product is conveyed between furnace sections or chambers of a furnace.

Process For Solid Oxide Fuel Cell Manufacture

US Patent:
2005008, Apr 28, 2005
Filed:
Sep 10, 2004
Appl. No.:
10/939116
Inventors:
Donald Seccombe - Gloucester MA, US
Gary Orbeck - Windham NH, US
Srikanth Gopalan - Westborough MA, US
Uday Pal - Dover MA, US
International Classification:
H01M008/12, H01M004/86, C04B035/64
US Classification:
429030000, 264618000, 427115000, 429040000
Abstract:
The present invention provides a method for conveniently manufacturing a solid oxide fuel cell (SOFC) at a cost that is less than five-hundred dollars per kilowatt of electricity. The method comprises forming an electrode layer and depositing an electrolyte material on the surface of the electrode. The formed structure is an electrode-electrolyte bi-layer. A second electrode is deposited onto this bi-layer to form a multilayer fuel cell structure comprising an electrolyte positioned between two electrodes. This multilayer structure is then heated and fired in a single thermal cycle to remove any binder materials and sinter, respectively, the fuel cell. This thermal cycle can be performed in a furnace having one or more chambers. The chamber(s) preferably contains a variable or multiple frequency microwave source for heating the cell and removing binder materials in the electrolyte and electrode structures. The chamber(s) also preferably include a convection and/or radiation source for sintering the fuel cell. In addition, the method of the invention harmonizes and minimizes the deviation among the thermophysical properties of the electrolyte and electrode structures. This harmonization reduces and minimizes the temperature gradient within the cell such that the structure can be uniformly heated and fired during the thermal cycle. The multilayer structure is also unlikely to distort and fracture by minimizing the temperature gradient in the cell. An SOFC can also be manufactured by the present method in an order of magnitude less time than standard processes.

US Patent:
2004022, Nov 18, 2004
Filed:
Apr 7, 2004
Appl. No.:
10/819225
Inventors:
Chun Dong - Macungie PA, US
Wayne McDermott - Fogelsville PA, US
Alexander Schwarz - Bethlehem PA, US
Gregory Arslanian - Pipersville PA, US
Richard Patrick - Tamaqua PA, US
Gary Orbeck - Windham NH, US
Donald Seccombe - Gloucester MA, US
International Classification:
B23H009/00
US Classification:
205/658000
Abstract:
