摘要： A container for fuel cells is made from an iron aluminide alloy. The container alloy preferably includes from about 13 to about 22 weight percent Al, from about 2 to about 8 weight percent Cr, from about 0.1 to about 4 weight percent M selected from Zr and Hf, from about 0.005 to about 0.5 weight percent B or from about 0.001 to about 1 weight percent C, and the balance Fe and incidental impurities. The iron aluminide container alloy is extremely resistant to corrosion and metal loss when exposed to dual reducing and oxidizing atmospheres at elevated temperatures. The alloy is particularly useful for containment vessels for solid oxide fuel cells, as a replacement for stainless steel alloys which are currently used.

摘要： A hydrocarbon reforming catalyst material comprising a catalyst support impregnated with catalyst is provided for reforming hydrocarbon fuel gases in an electrochemical generator. Elongated electrochemical cells convert the fuel to electrical power in the presence of an oxidant, after which the spent fuel is recirculated and combined with a fresh hydrocarbon feed fuel forming the reformable gas mixture which is fed to a reforming chamber containing a reforming catalyst material, where the reforming catalyst material includes discrete passageways integrally formed along the length of the catalyst support in the direction of reformable gas flow. The spent fuel and/or combusted exhaust gases discharged from the generator chamber transfer heat to the catalyst support, which in turn transfers heat to the reformable gas and to the catalyst, preferably via a number of discrete passageways disposed adjacent one another in the reforming catalyst support. The passageways can be slots extending inwardly from an outer surface of the support body, which slots are partly defined by an exterior confining wall. According to a preferred embodiment, the catalyst support is non-rigid, porous, fibrous alumina, wherein the fibers are substantially unsintered and compressible, and the reforming catalyst support is impregnated, at least in the discrete passageways with Ni and MgO, and has a number of internal slot passageways for reformable gas, the slot passageways being partly closed by a containing outer wall.

摘要： Solid-state ionic or electrochemical devices can depend critically on the proper formation of a dense, Gd-doped ceria (GDC) layer on a porous substrate. Devices and methods of the present invention are characterized by the formation of a transitional buffer layer, which is less than 10 microns thick and comprises GDC, located between the porous substrate and the dense GDC layer. The transitional buffer layer provides a practical way to form the dense GDC layer on the porous substrate without cracks in the GDC layer and without clogging the pores of the substrate.

摘要： A method of manufacturing thin foil alloys through a series of steps. A carrier having a polished carrier surface is placed within a deposition chamber. The carrier surface is generally polished to a mirrored surface finish. A sacrificial layer is applied atop the carrier surface. The sacrificial layer is made of a material that may be easily dissolved or separated from the carrier surface to remove the metal foil. The carrier surface and sacrificial layer are placed within the deposition chamber. The sacrificial layer is exposed to an evaporated first metal which becomes deposited upon the sacrificial layer. An evaporated second metal is then applied concurrently or sequentially with the first metal. The first and second evaporated metals solidify on the sacrificial layer to form a multilayer foil. At this point, the multilayer foil includes discrete layers or areas of the evaporated metals.
