| 20080206606 | Cathode For a Large-Surface Fuel Cell - A cathode for high-temperature fuel cell, comprising a layer of porous particles applied on a sintered electrolyte, the layer having a surface area of 15 to 900 m | 08-28-2008 |
| 20080220310 | Protection for Anode-Supported High-Temperature Fuel Cells Against Reoxidation of the Anode - Anode-supported high-temperature fuel cells with a substrate and an anode of stabilised zirconium dioxide and metallic nickel can be destroyed by air penetrating on the fuel gas side. Reoxidation causes the volume of the nickel in the anode to change. The resultant mechanical stresses may destroy the gas-impermeable electrolyte. The invention provides oxygen scavengers that can be produced at low cost for the anode, which more effectively bind the oxygen that penetrates on the fuel gas side than oxygen scavengers according to the prior art. | 09-11-2008 |

| 20090317762 | IMPLANTS WITH POROUS OUTER LAYER, AND PROCESS FOR THE PRODUCTION THEREOF - Provided are implants having a porous coating, comprising an implant core made of solid material and a sleeve fitted thereon, wherein the sleeve comprises an outer porous region in addition to an inner non-porous region. The invention further provides a method for joining the solid implant core and a sleeve comprising an outer porous region as well as an inner non-porous region. | 12-24-2009 |
| 20100028757 | CERAMIC MATERIAL COMBINATION FOR AN ANODE OF A HIGH-TEMPERATURE FUEL CELL - The invention relates to an anode for a high-temperature fuel cell having an anode substrate and/or a functional anode layer, comprising a porous ceramic structure having a first predominantly electron-conducting phase with the general empirical formula Sr | 02-04-2010 |
| 20100310407 | METHOD FOR PRODUCING SEMI-FINISHED PRODUCTS FROM NITI SHAPE MEMORY ALLOYS - Disclosed is a method for producing semi-finished products from a shape memory alloy, particularly an NiTi shape memory alloy, wherein a powder is first produced from a shape memory alloy, and subsequently the powder is divided into a coarse fraction and a fine fraction in a separating cut T. While the fine fraction is required, in particular, for the production of a first semi-finished product, employing the metal injection molding (MIM) method, the coarse fraction can be used for the production of a second semi-finished product, employing the hot isostatic pressing (HIP) method. The advantages of the invention can be summarized as follows. The MIM method for producing semi-finished products from a shape memory alloy is qualitatively improved and more cost-effective to implement if the coarse fraction that is typically obtained during powder production, but not used for the MIM process, can advantageously be supplied to a further process, in this case the HIP process. Due to the use of particularly fine powder, the semi-finished products produced by way of the MIM method have an advantageous, powder-metallurgical microstructure. In particular, the alloying elements are distributed particularly homogeneously in these semi-finished products, casting flaws or segregations do not usually occur, no anisotropy of the structure occurs as a result of the processing steps, and ternary alloys can be processed, which due to the mechanical properties thereof, cannot be processed by way of conventional forming methods. | 12-09-2010 |
| 20110020192 | OXYGEN-PERMEABLE MEMBRANE AND METHOD FOR THE PRODUCTION THEREOF - The invention relates to a composite membrane for selective gas separation, comprising a layer system having a through-and-through porous, mechanically stable carrier layer, which has an average pore size in the μm range, further having at least one through-and-through porous intermediate layer, which is disposed on the carrier layer and has an average pore size in the range between 2 and 200 nm, and further having a gas-tight functional layer, which is disposed on the intermediate layer and is made of mixed-conductive material having a maximum layer thickness of 1 μm. The carrier layer comprises structural ceramics, a metal or a cermet and has a layer thickness of no more than 1 mm. The intermediate layer is present in a total layer thickness of no more than 100 μm and has an average pore size in the range of 10 and 100 nm. The functional layer comprises a perovskite, a fluorite, or a material having a K | 01-27-2011 |
