Abstract: Various embodiments of a reactant feed and return assembly, such as an anode splitter plate (ASP), are provided for facilitating reactant feed and exhaust flow in a solid oxide fuel cell (SOFC) stack system. Embodiments include a reactant feed and return assembly including at least a first portion formed of a chromium-based alloy, such as a chromium-iron alloy, having a similar coefficient of thermal expansion as other SOFC components and may therefore reduce internal stress in an SOFC stack. Methods for making an a reactant feed and return assembly comprising a chromium-based alloy are also provided.

Abstract: Methods for fabricating an interconnect for a fuel cell system that include forming a metal powder into a preform structure, positioning the preform structure in a die cavity of a press apparatus, and compressing the preform structure in the press apparatus to form the interconnect. Further embodiments include use of thin inserts in the die cavity to provide reduced permeability and/or including filler material in the die cavity.

Abstract: A method of making an interconnect for a solid oxide fuel cell stack includes providing a chromium alloy interconnect and providing a nickel mesh in contact with a fuel side of the interconnect. Formation of a chromium oxide layer is reduced or avoided in locations between the nickel mesh and the fuel side of the interconnect. A Cr—Ni alloy or a Cr—Fe—Ni alloy is located at least in the fuel side of the interconnect under the nickel mesh.

Abstract: A drain valve device includes a base and a control unit removably disposed in the base. The control unit includes a valve and a resilient component positioned between the valve and the base. The drain valve device opens automatically as soon as water entering the base exceeds a predetermined level. The drain valve device shuts automatically as soon as water entering the base is less than a predetermined level. The drain valve device has advantages, namely simple structure, convenient of use, prevention of intrusion of odor and pests, easy to clean, and unlikely to get clogged.

Abstract: An apparatus for processing a substrate, comprising: a process chamber having a track; a carrier connected to the track; upper and lower proximity heads in the chamber and positioned along the path, the proximity heads having opposing faces that define a gap in which a meniscus of fluid is formed, the path being defined along the gap between the opposing faces; a first pre-wet dispenser and a second pre-wet dispenser disposed along side of the upper proximity head and directed toward the path; a drive for moving each of the pre-wet dispensers between a center position along the length of the upper proximity head and opposite outer positions near outer ends of the upper proximity head; and a pre-wet controller for causing the drive to move each of the first and second pre-wet dispensers based on a position of the carrier when moved under the first and second pre-wet dispensers.

Abstract: A method suctions liquid from an upper surface of a substrate as the substrate is transported by a carrier under a head in a chamber. This operation is performed by the first section of the head. The method causes a first film of cleaning foam to flow onto the upper surface of the substrate as the substrate proceeds under the head. This operation is performed by a second section which is contiguous to the first section in the head. The method causes a second film of rinsing fluid to flow onto the upper surface of the substrate as the substrate is carried under the head. This rinsing operation is performed by a third section which is contiguous to the second section in the head and which is defined partially around the second section and up to the first section.

Abstract: Quantum dot-sensitized solar cell and manufacturing method thereof are provided. The proposed quantum dot-sensitized solar cell has a counter electrode with a PbS thin-film layer and a polysulfide electrolyte contacting the PbS thin-film layer.

Abstract: Various embodiments include fuel cell interconnects having a fuel distribution portion having an inlet opening, a fuel collection portion having an outlet opening, and a primary fuel flow field containing channels, wherein the fuel distribution portion comprises at least one raised feature defining a fuel distribution flow path, and the fuel distribution flow path is not continuous with the channels in the primary fuel flow field. The at least one raised feature may include, for example, a network of ribs and/or dots. Further embodiments include interconnects having a fuel distribution portion with a variable surface depth to provide variable flow restriction and/or a plenum with variable surface depth and raised a raised relief feature on the cathode side, and/or varying flow channel depths and/or rib heights adjacent a fuel hole.

Abstract: A head for dispensing a thin film of a fluid over a substrate is disclosed. The head includes a body assembly that extends between a first and a second end that is at least a width of the substrate. The body includes a main bore that is defined between the first and the second ends, the main bore connected to an upper side of a reservoir through a plurality of feeds that are defined between the main bore and the reservoir. The body also includes a plurality of outlets connected to a lower side of the reservoir and extends to an outlet slot. The plurality of feeds has a larger cross-sectional area than the plurality of outlets and the plurality of feeds are fewer than the plurality of outlets. The fluid is configured to flow through the main bore, through the plurality of feeds along the bore and fill the reservoir up to at least the threshold level before fluid is evenly output as a film out of the outlet slot onto the substrate.

Abstract: A handheld electronic device includes a first body, a second body, a flexible electrical connector, and a protection cover. The second body is slidably stacked with the first body. The flexible electrical connector is electrically connected between the first body and the second body. The cover is slidably disposed between the first body and the second body. The cover is at an initial position when the first body and the second body are in a stacked state. The cover shields the flexible electrical connector exposed after the second body moves when the first body and the second body are in a spread state. As a result, the lifetime of the handheld electronic device can be prolonged. Additionally, the available region of the handheld electronic device in the spread state can be increased to provide higher design flexibility.
