摘要: A reaction cell for a flow battery having flow channels positioned within a recess of a non-porous and non-brittle housing that is also a dielectric. Positioning the flow channels within the recess eliminates the need for end plates, gaskets, and insulators of conventional designs. A current collector and an electrode within the recess have areas approximately equal to the area of the recess such that they fit within the recess and maximize the contact area between them.

摘要: A method and system provide a fitting system for a flexible fuel cell of an aircraft. The fitting system may include a flexible fuel cell and a fitting. The fitting may have a peripheral flange with a series of slots spaced about the flange. A series of fabric strips may be threaded into the slots of the fitting and one or more adhesives may couple the fabric strips to the fuel cell. The fabric strips may extend out around the periphery of the fitting to provide a uniform contact surface area with the fuel cell. The fabric strips may be separated by fuel cell material. The fabric strips may be made from one or more materials for enclosing or holding fuel. The fitting may further include threaded holes wherein the threaded holes may receive fasteners to couple the fitting to the fuel equipment of an aircraft.

摘要: A method of rebalancing electrolytes in a redox flow battery system comprises directing hydrogen gas generated on the negative side of the redox flow battery system to a catalyst surface, and fluidly contacting the hydrogen gas with an electrolyte comprising a metal ion at the catalyst surface, wherein the metal ion is chemically reduced by the hydrogen gas at the catalyst surface, and a state of charge of the electrolyte and pH of the electrolyte remain substantially balanced.

摘要: An electrode catalyst for an oxygen reduction reaction including intermetallic L10-NiPtAg alloy nanoparticles having enhanced ORR activity and durability. The catalyst including intermetallic L10-NiPtAg alloy nanoparticles is synthesized by employing silver (Ag) as a dopant and annealing under specific conditions to form the intermetallic structure. In one example, the intermetallic L10-NiPtAg alloy nanoparticles are represented by the formula: NixPtyAgz wherein 0.4≤x≤0.6, 0.4≤y≤0.6, z≤0.1.

摘要: An electrochemical cell stack comprises a plurality of electrochemical cell units, each comprising a cathode, an anode, and an electrolyte, and also comprises a plurality of interconnects. An interconnect is disposed between adjacent electrochemical cell units and defines a longitudinal channel having circumferential corrugations defined therearound. A fuel channel is defined between each anode and a respective adjacent interconnect, the fuel channel having fuel inlet and outlet. An oxidant channel is defined between each cathode and a respective adjacent interconnect, the oxidant channel having an oxidant inlet and outlet. The plurality of electrochemical cell units and interconnects include a first electrochemical cell unit, a first interconnect adjacent the first electrochemical cell unit, a second electrochemical cell unit adjacent the first interconnect, and a second interconnect adjacent the second electrochemical cell unit. The second interconnect is rotationally offset from the first interconnect about a longitudinal axis of the fuel cell stack.

摘要: A method for manufacturing a membrane assembly for a fuel cell. To overcome a problem of chemical degradation at an edge of the membrane, the method comprises the following steps: positioning a first decal layer, which is made of the same material as a first catalyst layer, on a first side of the membrane, positioning a second decal layer, which is made of the same material as a second catalyst layer, on a second side of the membrane, pressing a compression pad, which is positioned on the first decal layer with the first decal layer and the second decal layer fully overlapping the compression pad, and the second decal layer against each other with the first decal layer and the membrane positioned in-between, whereby pressure on the first and the second decal layer is applied only in an area covered by the compression pad.

摘要: The invention relates to a device (1) for Converting chemical energy into electrical energy, or electrical energy into chemical energy, having at least one electrochemically active, planar cell (2) that is held securely between coaxial annular disks (10a, 10b, 10c, 10d) of an electrically insulating support frame (10), through which a supply structure with Channels (22, 23, 13, 33) for process media extends to the cell (2). A free spatial region (8a, 8b) is present on either side of the cell (2) in the axial direction, which region is bounded in the radial direction by at least one of the annular disks (10a, 10b). The spatial regions (8a, 8b) are open toward a pressure Chamber (5) via at least one passage (42a, 42b) through the corresponding annular disk (10a, 10b). When the device (1) is in Operation, the pressure Chamber (5) is filled with a pressurized medium, as a consequence of which the cells are compressed. In this manner, the device (1) according to the invention combines the advantages of a conventional Stack of cells (2, 2′) with a hydraulic or pneumatic compression.

摘要: A hybrid power system for an unmanned aerial system (UAS) having a liquid fuel engine and a solid oxide fuel cell coupled to the exhaust of the engine for generating electricity that is used by the electric motors of the UAS to create lift and control flight. A conventional remote control (r/c) liquid fuel engine may be used generate exhaust gases including hydrogen and carbon monoxide that are used by a SOFC coupled to the exhaust of the r/c engine to generate electricity. The electric motors of the UAS may thus be powered by the electricity generated by the SOFC.
