Patent number: 6843960Abstract: A method for preparing compositionally graded metallic plates and compositionally graded metallic plates suitable for use as interconnects for solid oxide fuel cells are provided. The method of the invention, utilizing powder metallurgy, enables making metallic plates of generally any desired composition to meet the corrosion requirements of fuel cells and other applications, and enables making metallic plates of graded composition from one surface of the plate to the other. A powder of the desired alloy composition is obtained, then solvents, dispersants, a plasticizer and an organic binder are added to form a slip. The slip is then formed into a layer on a desired substrate that can be flat or textured. Once dried, the layer is removed from the substrate and the binder is burned out. The layer is sintered in a reducing atmosphere at a set temperature for a predefined duration specific to the materials used and the desired final properties.Type: GrantFiled: June 12, 2002Date of Patent: January 18, 2005Assignee: The University of ChicagoInventors: Michael Krumpelt, Terry Alan Cruse, John David Carter, Jules L.

Patent number: 6670305Abstract: A monolithic catalyst with micro-scale flow channels and methods of making such a monolithic catalyst are provided. The monolithic catalyst includes a plurality of thin catalyst walls. The walls have a set thickness in a range from 1 to 150 &mgr;m. The thin catalyst walls define a plurality of flow channels. A fugitive material is used to form the flow channels. The flow channels have a set width in a range from 1 to 200 &mgr;m. The flow channels are formed by an organic fugitive material, which burns off during processing. By using the thin catalyst walls and flow channels having a set width in a range from 1 to 200 &mgr;m, a reduced diffusion path length that molecules travel between the bulk gas and the active site is provided. Accelerating the mass transport thus improves the overall reaction rate, which allows processing of more reactants. Thus, the volume of the required catalyst is reduced, allowing more compact reactors.Type: GrantFiled: May 9, 2001Date of Patent: December 30, 2003Assignee: The University of ChicagoInventors: Joong-Myeon Bae, John David Carter, Michael Krumpelt, Shabbir Ahmed

Publication number: 20030232230Abstract: A solid oxide fuel cell (SOFC) repeat unit includes an oxide electrolyte, an anode, a metallic fuel flow field, a metallic interconnect, and a metallic air flow field. The multilayer laminate is made by casting tapes of the different functional layers, laminating the tapes together and sintering the laminate in a reducing atmosphere. Solid oxide fuel cell stacks are made by applying a cathode layer, bonding the unit into a gas manifold plate, and then stacking the cells together. This process leads to superior mechanical properties in the SOFC due to the toughness of the supporting metallic layers. It also reduces contact resistances in stacking the cells since there is only one physical contact plane for each repeat unit.Type: ApplicationFiled: June 12, 2002Publication date: December 18, 2003Inventors: John David Carter, Joong-Myeon Bae, Terry Alan Cruse, James Michael Ralph, Romesh Kumar, Michael Krumpelt
