    摘要： A textured surface is formed on at least one of a fuel cell mounting plate or fuel cell subassembly to define a joint spacing between these two components. In a preferred embodiment, the textured surface comprises a plurality of dimples coined or otherwise formed in the metal mounting plate. The joint spacing improves the manufacturing and assembly process of the fuel cell cassettes through precise application and control of the brazing process which improves the braze joint strength while reducing material cost.

    摘要： In a solid-oxide fuel cell assembly comprising a plurality of components having electrically-conductive mating surfaces therebetween, the surfaces are sealed by gasket elements that include first and second silver braze alloy layers and a dielectric layer, formed preferably of yttrium-stabilized zirconia (YSZ), disposed between the alloy layers. The alloy is capable of bonding to many ceramics, including YSZ, and is readily brazed to the oxide layer formed on many metals at elevated temperatures. Because the braze alloy is electrically conductive, a dielectric layer must be included to break conductivity in bonding applications where electrical insulation is required. YSZ functions as a reliable insulator and will not crystallize or fracture as do prior art glass insulators. The assembly is useful as an auxiliary power unit in a vehicle.

    摘要： A brazing alloy comprising elemental silver alloyed with elemental silicon in a silver/silicon ratio between about 95/5 and 99/1, preferably about 97/3. Small amounts of silicon alloyed with silver depress the alloy liquidus curve significantly, the liquidus temperature of a silver and silicon eutectic alloy being about 837° C. Brazing alloys in accordance with the invention are useful in bonding ceramics to ceramics, ceramics to metals, and metals to metals. Copper, vanadium, or other oxygen-reactive surface bonding elements may also be included. Silver/silicon alloys are useful in applications such as assembly of components of solid oxide fuel cells. A variety of silver/silicon alloy brazes can be used within the same fuel cell so that subsequent brazing can be performed without reliquifying a previous braze. A brazing alloy comprising elemental silver and ruthenium in a silver/ruthenium ratio between 97/3 and 99/1 is also included.

    摘要： In assembling an SOFC fuel cell stack from a plurality of cassettes, the mounting plate of one cassette is attached to, and insulated from, the separator plate of the next-adjacent cassette by a peripheral dielectric seal consisting of a ceramic coating and a metal braze. Materials suitable for the ceramic coating include yttrium stabilized zirconia (YSZ), zirconia toughened alumina, magnesium silicates such as the mineral forsterite, magnesium aluminates, magnesium aluminosilicates and lanthanum zirconate. The ceramic coating may be applied to the cassette's outer surface in known fashion as by physical vapor deposition, chemical vapor deposition, sputtering, and various methods of plasma spray. An underlayer of alumina may also be used to provide a redundant layer of electrical insulation.

    摘要： An electrical interconnect for a solid-oxide fuel cell stack assembly, including a novel sintering paste and an improved manufacturing process for an anode and cathode electrical contacts is disclosed. On the anode side, the paste contains a metallic oxide such as NiO, and an amount of sacrificial pore-forming particles, such as carbon particles or polymer spheres, which are vaporized during sintering of the paste, resulting in a very porous connection having good electrical conductivity and good adhesion. A preferred level of pore-former in the paste is about 40 volume percent. On the cathode side, the paste contains a noble metal such as for example, gold, platinum, palladium or rhodium, and an amount of the sacrificial pore-forming particles. The paste may be applied to the surfaces in a grid pattern or, because the resulting contact is porous after sintering, it may be applied as a continuous layer.
