Abstract:
A solid oxide fuel cell includes an anode layer, an electrolyte layer over the anode layer, and a cathode layer over the electrolyte layer, wherein at least one of the anode layer and the cathode layer defines at least one gas channel, the gas channel containing at least one support structure. The support structure can have a cross-sectional shape of an I-beam, an arch, a tube defining holes along its length, a porous cylinder, or a U-shaped brace. The support structure can be open at a portion of the gas channel most proximate to the electrolyte layer.
Abstract:
A solid oxide fuel cell includes an anode layer, an electrolyte layer over the anode layer, and a cathode layer over the electrolyte layer. At least one of the anode layer and the cathode layer defines a gas manifold. The gas manifold includes a gas inlet, defined by an edge of the anode layer or cathode layer, a gas outlet, defined by the same or a different edge of the anode layer or cathode layer, and a plurality of gas flow channels in fluid communication with the gas inlet and gas outlet. The gas flow channels can have diameters that conduct flow of gas from the gas inlet at substantially equal flow rates among the gas flow channels.
Abstract:
A composition having a plurality of abrasive particles including alumina, the plurality of abrasive particles have mesoporosity with an average meso branching index of at least 55 junctions/microns2 and a median particle size (D50) of at least 5 microns.
Abstract:
La presente divulgación se dirige a un polvo de alúmina alfa que tiene un área de superficie específica, un tamaño de cristalito específico y una distribución específica del tamaño de partícula para su uso en esmaltes abrasivos y método para hacer dicho polvo. El método para hacer el polvo de alúmina alfa puede incluir la calcinización de un polvo precursor de óxido de aluminio a una temperatura de 800-1500ºC y moliendo el polvo calcinado a la distribución de tamaño de partícula específica. El polvo de alúmina alfa revelado en este documento puede permitir rápidamente una alta tasa de eliminación con una calidad estética no disminuida cuando se usa en esmaltes abrasivos.
