摘要： A fuel cell and system for supply electrolyte, as well as fuel and an oxidant to a fuel cell stack having at least two fuel cells, each of the cells having a pair of spaced electrodes and a matrix sandwiched therebetween, fuel and oxidant paths associated with a bipolar plate separating each pair of adjacent fuel cells and an electrolyte fill path for adding electrolyte to the cells and wetting said matrices. Electrolyte is flowed through the fuel cell stack in a back and forth fashion in a path in each cell substantially parallel to one face of opposite faces of the bipolar plate exposed to one of the electrodes and the matrices to produce an overall head uniformly between cells due to frictional pressure drop in the path for each cell free of a large hydrostatic head to thereby avoid flooding of the electrodes. The bipolar plate is provided with channels forming paths for the flow of the fuel and oxidant on opposite faces thereof, and the fuel and the oxidant are flowed along a first side of the bipolar plate and a second side of the bipolar plate through channels formed into the opposite faces of the bipolar plate, the fuel flowing through channels formed into one of the opposite faces and the oxidant flowing through channels formed into the other of the opposite faces.

A smaller surface area is provided at the passage inlet, which increases toward the passage outlet, so as to provide more uniform cooling of the entire fuel cell. The cooling passages can also be spaced from one another in an uneven fashion.

摘要： A core-form transformer winding with liquid coolant flow diversion bands is disclosed. The apparatus includes a winding tube with a central longitudinal axis. A number of coil sections are axially displaced along the central longitudinal axis of the winding tube. Radial ducts are formed between the coil sections. Internal vertical ducts are formed within each of the coil sections. A liquid coolant is used to cool the windings during operation. Flow diversion bands are placed around every other coil section. The flow diversion bands generate a partial blockage of the liquid coolant, which produces a radial flow into one or more of the radial ducts, resulting in vertical flow through the internal vertical ducts.

摘要： A heat storage system provides overload capacity for a vaporization-cooled electrical apparatus. An external housing, containing a heat storage fluid, is disposed around a fluid conductor connecting a non-condensable gas storage reservoir and the radiator of a vaporization-cooled electrical apparatus. At normal loads, the non-condensable gas is contained within the fluid conductor and the storage reservoir thereby thermally isolating the storage fluid from the hot vapors contained within a radiator which keeps the storage fluid at ambient temperatures. A pressure increase, caused by an overload, compresses the non-condensable gas into the storage reservoir and allows the hot vapors to flow into a portion of the fluid conductor surrounded by the external housing whereby heat is dissipated from the hot vapors to the storage fluid contained within the external housing. Additional heat storage capacity is provided by a pressure relief valve in the external housing which allows the storage fluid contained therein to reach its boiling point and vaporize.

摘要： A water-cooled turbine rotor blade having an enlarged radially-extending chamber forming a coolant reservoir connected to cooling passages subadjacent the blade surface. The channels interconnecting the reservoir with the passages are adjacent the blade tip so that the pressurized water (i.e., due to the centrifugal force caused by the rotation) in the reservoir flows into the channels at the tip and thence through the cooling passages radially inwardly. Heat absorption from the blade causes vaporization of the water as it flows through the passages. The cooling passages terminate radially inwardly (adjacent the hub or root portion) in a space in flow communication with the enlarged chamber and an exhaust port in the downstream face of the root so that vapor is exhausted at the downstream face and any liquid exiting the coolant passages is returned to the reservoir.

摘要： An improved vapor-cooled terminal-bushing is provided for increased current-carrying capacity, such as 6,000 amperes, for example, in an oil-type circuit-breaker, being provided with a "dry" body portion, utilizing resinous materials, such as epoxy-resin formulations, for example.Preferably, the body portion of resinous materials, such as epoxy resin, for example, is composite, or of a two-piece construction, having an inner first epoxy-resin formulation having improved dielectric strength, and an outer-disposed externally-located "petticoat"-type insulating second body portion, having weather-sheds, the second weather-shed annular body portion being preferably cast directly onto the inner high-dielectric-strength first epoxy-body portion, and having some flexibility for adherence purposes.An externally-located tubular metallic preferably finned heat-exchanger or cooling condenser, having a tubular central hub portion, constitutes an extension of the inner, elongated, tubular, high-voltage terminal-lead, which is partially filled with a low-boiling-point cooling liquid or refrigerant, such as "Freon-11", for example. A massive metallic line-terminal connector is affixed to the terminal-lead intermediate the location of the heat-exchanger and the adjacent end of the body portion for additional heat-dissipation purposes. A pressure gauge is attached at the upper end of the heat-exchanger in vapor communication with the cooling liquid within the terminal-lead.
