Abstract: A cooling apparatus for fuel cell components is provided wherein the cooling apparatus comprises a base plate having an upper section and a lower section. A plurality of upper ribs and a plurality of lower ribs are coupled to the upper section and the lower section, respectively. Each of the plurality of upper ribs and lower ribs define an upper serpentine channel and a lower channel wherein such channels are formed between each of the plurality of upper ribs and lower ribs, respectively. In addition, the upper serpentine channel and the lower channel are fluidically coupled by at least one cavity disposed in the base plate wherein the upper serpentine channel and the lower channel are disposed to allow a flow of a fluid therethrough so as to enhance the heat transfer between the fluid and the fuel cell components.
Abstract: Europium-activated phosphors comprise oxides of at least a rare-earth metal selected from the group consisting of gadolinium, yttrium, lanthanum, and combinations thereof and at least a Group-IIIB metal selected from the group consisting of aluminum, gallium, indium, and combinations thereof. A method for making such phosphors comprises adding at least a halide of at least one of the selected Group-IIIB metals in a starting mixture. The method further comprises firing the starting mixture in an oxygen-containing atmosphere. The phosphors produced by such a method exhibit improved absorption in the UV wavelength range and improved quantum efficiency.

Abstract: A method for manufacturing a fuel cell assembly, and a fuel cell assembly produced by the method, are provided, with the method comprising providing at least one fuel cell unit, wherein providing the at least one fuel cell unit comprises providing at least one substrate; and disposing at least one fuel cell component layer on the at least one substrate, the at least one component layer comprising at least one of an interconnect, an anode, a cathode, and an electrolyte; wherein disposing comprises depositing the at least one component layer using an expanding-thermal-plasma coating apparatus.
Abstract: An article comprising a substrate having a barrier layer. The barrier layer is disposed on the surface of the substrate and resistant to transmission of moisture and oxygen. Methods of depositing such a barrier layer on the substrate are also disclosed. The article may include additional layers, such as, but not limited to, an adhesion layer, abrasion resistant layers, radiation-absorbing layers, radiation-reflective layers, and conductive layers. Such articles include, but are not limited to, light emitting diodes (LEDs), liquid crystal displays (LCDs), photovoltaic articles, electrochromic articles, and organic electroluminescent devices (OELDs).
Abstract: A flow control device for a combustor is provided in which the flow control device comprises a shroud having a first end and a second end wherein the second end is coupled to the combustor. The shroud is disposed to receive a primary fluid and disposed to direct the primary fluid into the combustor. In addition, the shroud further comprises a plurality of ports disposed therein wherein the ports are oriented to extract a portion of a flow from a flow path of the primary fluid so as to control a flow rate of the primary fluid through the shroud.
