    摘要： A fast light off flow-through ceramic substrate is provided that is particularly adapted for use as a catalytic converter. The substrate is formed from a body of ceramic material having axially opposing inlet and outlet ends for receiving and expelling the flow of automotive exhaust gas, respectively. The body contains a network of walls coated with a catalyst that define axially-oriented flow-through cell channels. The average thermal mass (ATM1) of a first axial region of the walls adjacent to the inlet end is at least 20% less than the average thermal mass (ATMTOT) of all of the walls. The lower average thermal mass of the walls in the first region advantageously shortens the light off time for the catalyst within the substrate to effectively neutralize automotive pollutants. The reduction of the average thermal mass in only the first axial region of the walls advantageously maintains the strength of the resulting body of ceramic material, and further increases the cool down time of the body.

    摘要： Disclosed are seals and seal structures for use in electrochemical devices such as solid oxide fuel cell devices. Exemplary seal structures are configured such that at least a portion of the interface between the seal and electrolyte sheet deviates from planarity by extending either (i) upwardly and inwardly (ii) or downwardly and inwardly, toward the active portion of the electrolyte sheet surface where one or more device electrodes are deposited. By angling the seal portion of the electrolyte sheet, the sharpness of any resulting bends or deformations that may occur during use can be reduced, thus reducing the likelihood of any cracks forming in the typically high stress regions of the electrolyte sheet. Further, preferably at least a portion of the electrolyte sheet contacting the seal composition, the seal-electrolyte interface may deviate from planarity by at least 0.1 mm from the seal-electrolyte interface, where the deviation from planarity extends normal to the seal or inwardly toward the active surface region of the electrolyte sheet. Also disclosed are methods for manufacturing the inventive seal structures and electrochemical device assemblies comprising same.

    摘要： A trough filter integrated with a thermoelectric generator includes annular filter modules having a support structure at its inner circumference, a filter element, and a support structure at its outer circumference. The filter elements may be configured to form troughs. An annular exhaust gas outlet channel or gas inlet channel may be formed between filter modules. The thermoelectric generator may be positioned in the exhaust gas outlet or inlet channel. A vehicle includes the trough filter integrated with a thermoelectric generator downstream from an internal combustion engine. A method of treating exhaust gas uses a trough filter with an integrated thermoelectric generator.

    摘要： A stress reducing mounting for an electrolyte sheet assembly in a solid electrolyte fuel cell is provided that includes a support frame or manifold having an inner edge portion that supports a peripheral portion of the sheet assembly, a seal that affixes an edge of the peripheral portion to the frame or manifold, and a stress reducer disposed around the peripheral portion of the electrolyte sheet and the frame or manifold that reduces tensile stress in the peripheral portion of the electrolyte sheet when the peripheral portion is bent by pressure differentials or thermal differential expansion. The stress reducer is at least one of a convex curved surface on the inner edge portion of the frame or manifold that makes area contact with the peripheral portion when it bends in response to a pressure differential or thermal differential expansion, and a stiffening structure on the sheet peripheral portion that renders the ceramic sheet material forming the peripheral portion more resistant to bending. The stress reducing mounting reduces cracking in the electrolyte sheet at the peripheral portions due to tensile forces.
