摘要:
Disclosed herein is a separator for a molten carbonate fuel cell, the separator including four steel sheets in which edges of the four steel sheets are joined to each other thereby providing three spaces therebetween, comprising a cathode channel, serving as a flow path of oxidant gas, formed in the first space; an anode channel, serving as a flow path of fuel gas, formed in the second space such that the anode channel is separated from the cathode channel; and a fuel gas reforming channel formed in the third space, which is located between the first space and the second space. The separator for a molten carbonate fuel cell is advantageous in that the volume of the fuel cell is decreased, and the structure thereof is simple, thus reducing the production cost thereof.
摘要:
A water-cooled stator bar clip for electrical generators and a method for applying a corrosion-resistant protective coating, preferably Sc, Ti, Cr, Zr, Nb, Mo, Hf, Ta, W, Ni, and Al, and their alloys or oxides to existing stator bar end fittings in order to significantly reduce the possibility of leaks through the brazed connections of the copper stator bar end connections. The coatings can be applied locally using various known physical vapor deposition (“PVD”), chemical vapor deposition (“CVD”) or other direct coating techniques known in the art. For example, the coatings can be applied using ion plasma deposition, sputtering or wire arc techniques (all PVD processes) or by using electroplating, high velocity oxygen free (“HVOF”) deposition, DC arc or electroless plating. Preferably, the coatings are applied either to new stator bar clips or to existing clips in the field.

摘要:
A method and system for reducing stress corrosion cracking in a hot water system, such as a nuclear reactor, by reducing the electrochemical corrosion potential of components exposed to high temperature water within the structure. The method includes the steps of: providing a reducing species to the high temperature water; and providing a plurality of noble metal nanoparticles having a mean particle size of up to about 100 nm to the high temperature water during operation of the hot water system. The catalytic nanoparticles, which may contain at least one noble metal, form a colloidal suspension in the high temperature water and provide a catalytic surface on which a reducing species reacts with least one oxidizing species present in the high temperature water. The concentration of the oxidizing species is reduced by reaction with the reducing species on the catalytic surface, thereby reducing the electrochemical corrosion potential of the component.

An electrochemical corrosion potential sensor is fabricated by initially joining an electrical conductor to a sensor tip. An electrical cable is joined to the tip conductor. Ceramic powder is fused under heat around the tip conductor to form an integral annular electrically insulating band therearound to insulate the tip from the cable. The band may be formed by plasma spraying, or it may be molded and sintered to seal it to the tip and conductor without brazing. In a preferred embodiment, the band is formed of yttria-stabilized-zirconia or magnesia-stabilized-zirconia.

A lighting device may be provided that includes: a first to a fourth light emitting devices which are disposed on a substrate a first and a second pulse width modulation controllers which perform a pulse width modulation on currents applied to the first and the second light emitting devices respectively; and a first and a second controllers which control respectively currents applied to the third and the fourth light emitting devices having color temperatures different from those of the first and the second light emitting devices, wherein an (x, y) coordinate, which is determined by the mixture of the lights emitted from the first to the fourth light emitting devices and is located within a 1931 CIE chromaticity diagram, is moved onto a black body radiation curve within the 1931 CIE chromaticity diagram through the pulse width modulation of the first and the second pulse width modulation controllers and the control of the first and the second controllers.
摘要:
There is provided a fuel rod assembly comprising a first component of a zirconium-based material. The first component is in contact with or is located adjacent to a second component of a material different from the zirconium-based material, e.g. a nickel-based or iron-based alloy. A coating is disposed on an outer surface of the first component, which is effective to reduce an electrochemical corrosion potential difference between the first component and the second component relative to an electrochemical corrosion potential difference between the first component and the second component without the coating.
