摘要:
According to one embodiment of the invention a fuel cell device array monolith comprises at least three planar electrolyte sheets having two sides. The electrolyte sheets are situated adjacent to one another. At least one of the electrolyte sheets is supporting a plurality of anodes situated on one side of the electrolyte sheet; and plurality of cathodes situated on the other side of the electrolyte sheet. The electrolyte sheets are arranged such that the electrolyte sheets with a plurality of cathodes and anodes is situated between the other electrolyte sheets. The at least three electrolyte sheets are joined together by sintered fit, with no metal frames or bipolar plates situated therebetween.

摘要:
A filter apparatus comprises a filter stack including a plurality of porous ceramic plates that are axially spaced from one another to define plurality of axially spaced apart radial flow areas. In one example, the filter stack is mounted within a housing. In further examples, the plurality of porous ceramic plates alternate between a first set of porous ceramic plates that are nested with a second set of porous ceramic plates. In still further examples, at least one of the sides of the porous ceramic plates defines a plurality of radial flutes arranged in a radial array.

Zeolite-based honeycomb bodies and methods of manufacturing same. Zeolite-based honeycomb bodies especially suited for engine exhaust treatment applications include a primary phase comprising a zeolite having a SiO2 to Al2O3 molar ratio in the range from 5 to 300. The zeolite-based composites are porous with an open porosity of at least 25% and a median pore diameter of at least 1 micron. The zeolite-based honeycomb bodies can be manufactured by an extrusion method.
