    摘要: A seal composition includes a first alkaline earth metal oxide, a second alkaline earth metal oxide which is different from the first alkaline earth metal oxide, aluminum oxide, and silica in an amount such that molar percent of silica in the composition is at least five molar percent greater than two times a combined molar percent of the first alkaline earth metal oxide and the second alkaline earth metal oxide. The composition is substantially free of boron oxide and phosphorus oxide. The seal composition forms a glass ceramic seal which includes silica containing glass cores located in a crystalline matrix comprising barium aluminosilicate, and calcium aluminosilicate crystals located in the glass cores.

    摘要: The ferritic iron alloy is particularly suitable as a material for current collectors used in SOFC solid electrolyte high-temperature fuel cells. The material has a high chromium content upwards of 22% by weight, and a molybdenum content of 1 to 10% by weight. Additionally, there is provided 0.01 to 1.5% by weight of yttrium, rare earth metals, and/or their oxides. The alloy in particular has a high resistance to corrosion under the standard cell atmospheres in the temperature range from 700° to 900° C.

    摘要: A solid oxide fuel cell (SOFC) stack includes a plurality of SOFCs, and a plurality of interconnects, each interconnect containing a conductive perovskite layer on an air side of the interconnect. The stack in internally manifolded for fuel and the conductive perovskite layer on each interconnect is not exposed in the fuel inlet riser. The SOFC electrolyte has a smaller roughness in regions adjacent to the fuel inlet and fuel outlet openings in the electrolyte than under the cathode or anode electrodes.

    摘要: Highly dense shaped parts are produced with a powder metallurgic process. The parts are formed of an alloy that, besides of at least 20 weight % chromium, consists of iron and one or several additional alloy portions that in sum do not amount to more than 10 weight %. The part is produced by pressing and sintering to near final shape a ready-to-press powder where the additional alloy portions are introduced in form of a master-alloy powder. The master-alloy may contain the following variations: the additional alloy portions and the iron portions; or the additional alloy portions, the iron parts, and the chromium portions; or additional alloy portions and the chromium portions.
