    摘要： 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.

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 K2NiF4structure, such as La1-xSrxCo1-yFeyO3-δ(LSCF). The layer thickness of the functional layer is no more than 50 nm, particularly between 25 and 400 nm. In order to produce said composite membrane, at least one porous intermediate layer is applied onto a through-and-through porous, mechanically stable carrier layer, which has an average pore size in the μm range, said intermediate layer having an average pore size in the range between 2 and 200 nm.

    摘要： 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.

The carrier layer comprises a structural ceramic, a metal, or a cermet and has a layer thickness of no more than 1 mm. The intermediate layer is present with a total layer thickness of no more than 100 μm and has an average pore size in the range of 10 to 100 nm.
