    摘要： An air treatment system includes a filter and heating element, a plasma device, and a photocatalyst and UV light that cooperate to purify an air stream flowing through the air treatment system and protect the photocatalyst from passivating effects of certain contaminants. The air treatment system operates in two different modes. In the first mode, the air treatment system primarily draws air from and returns air to a space, and the heating element and plasma device are selectively shut off. In the second mode, the air treatment system regenerates the filter using the heating element to selectively heat the filter and release adsorbed contaminants. The plasma device is selectively turned on and chemically transforms the released contaminants into solid contaminant products. The solid contaminant products are deposited on a biased electrode of the plasma device. The UV light is turned off to ensure that the photocatalyst is inoperable during the release and transformation of the contaminants. Once deposited, the essentially immobile and inert solid contaminant products are unlikely to damage the photocatalyst.

    摘要： A fuel cell stack includes a plurality of fuel cells each having an anode layer, an electrolyte layer, and a cathode layer, the fuel cells each having a first effective thermal expansion coefficient; a plurality of bipolar plates positioned between adjacent fuel cells having an anode interconnect, a separator plate, and a cathode interconnect, the bipolar plates being positioned between adjacent fuel cells, wherein the anode interconnect is in electrical communication with the anode layer of one adjacent fuel cell, wherein the cathode interconnect is in electrical communication with the cathode layer of another adjacent fuel cell, and wherein at least one interconnect of the cathode interconnect and the anode interconnect has a second thermal expansion coefficient and is adapted to reduce strain between the at least one interconnect and an adjacent fuel cell due to differences between the first and second thermal expansion coefficients over repeated thermal cycles.

    摘要： The present invention is a process for modifying the properties of a porous freeform fabricated part by increasing its density and reducing its porosity. The porosity and density of a freeform fabricated part are altered by packing the pores in a freeform part with an infiltrant, such as a preceramic polymer. The process includes drawing a vacuum on or pressurizing the freeform part while it is in an infiltrant bath, thereby forcing the infiltrant into the pores of the freeform part. After removing the densified freeform part from the infiltrant bath, the freeform part is subjected to a treating process, such that the infiltrant within the pores transforms to a ceramic or ceramic-containing phase to thereby increasing the density of the freeform part.
