摘要： An electrically-conductive mesh spacer incorporated into the hydrogen and air gas flow spaces between each anode and cathode and its adjacent interconnect in a fuel cell stack. The mesh is formed of metal strands and is formed into a predetermined three-dimensional pattern to make contact at a plurality of points on the surfaces of the electrode and the interconnect element. The formed mesh spacer is secured as by brazing to the interconnect element at a plurality of locations to form an interconnect, which preserves the pattern during assembly of a fuel cell stack. The height of the formed pattern is greater than the height of a gas flow space after fuel cell assembly, such that the mesh spacer is slightly compressed during assembly of a fuel cell stack. Because the metal mesh is both compliant and resilient, the compressed spacer is continuously urged into mechanical and electrical contact with its electrode over all temperatures and pressures to which the fuel cell assembly may be subjected during use.
摘要翻译：导电网格隔离物，其结合在燃料电池堆中的每个阳极和阴极之间的氢气和空气气体流动空间及其相邻的互连中。网格由金属线形成，并且形成为预定的三维图案以在电极和互连元件的表面上的多个点处接触。形成的网格间隔件通过在多个位置处通过钎焊固定到互连元件上，以形成互连，其在燃料电池堆的组装期间保持图案。形成的图案的高度大于燃料电池组件之后的气体流动空间的高度，使得在燃料电池堆的组装期间网格间隔件被轻微地压缩。因为金属网既顺从又具有弹性，所以在使用期间燃料电池组件可能经受的所有温度和压力下，压缩间隔物被连续推动与其电极机械和电接触。

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： Nanocrystalline metal powders comprising tungsten, molybdenum, rhenium or niobium can be synthesized using a combustion reaction. Methods for synthesizing the nanocrystalline metal powders are characterized by forming a combustion synthesis solution by dissolving in water an oxidizer, a fuel, and a base-soluble, ammonium precursor of tungsten, molybdenum, rhenium, or niobium in amounts that yield a soichiometric burn when combusted. The combustion synthesis solution is then heated to a temperature sufficient to substantially remove water and to initiate a self-sustaining combustion reaction. The resulting powder can be subsequently reduced to metal form by heating in a reducing gas environment.

摘要： A method for joining together two or more ceramic and/or metal parts by providing a braze consisting of a mixture of copper oxide, silver, and ceramic particulate. The braze is placed upon the surfaces of the parts, which are then held together for sufficient time and at a sufficient temperature to cause the braze to form a bond between the parts. The addition of the ceramic particulate increases the viscosity of the braze, decreasing squeeze out, decreasing the formation of air pockets, decreases the formation of brittle phases by providing nucleation sites and increases the flexural strength of the joint.

摘要： Methods of aluminizing the surface of a metal substrate. The methods of the present invention do not require establishment of a vacuum or a reducing atmosphere, as is typically necessary. Accordingly, aluminization can occur in the presence of oxygen, which greatly simplifies and reduces processing costs by allowing deposition of the aluminum coating to be performed, for example, in air. Embodiments of the present invention can be characterized by applying a slurry that includes a binder and powder granules containing aluminum to the metal substrate surface. Then, in a combined step, a portion of the aluminum is diffused into the substrate and a portion of the aluminum is oxidized by heating the slurry to a temperature greater than the melting point of the aluminum in an oxygen-containing atmosphere.
