Abstract: A ceramic anode composition is formed of a multivalent metal oxide or oxygenate such as an alkali metal, transition metal oxygenate. The anode is prepared as a non-stoichiometric crystalline structure by reaction and conditioning in a hydrogen gas cover containing minor proportions of carbon dioxide and water vapor. The structure exhibits a single phase and substantially enhanced electrical conductivity over that of the corresponding stoichiometric structure. Unexpectedly, such oxides and oxygenates are found to be stable in the reducing anode fuel gas of a molten carbonate fuel cell.

Abstract: The present invention identifies several configurations of conducting elements capable of storing extremely high magnetic fields for the purpose of energy storage or for other uses, wherein forces experienced by the conducting elements and the magnetic field pollution produced at locations away from the configuration are both significantly reduced over those which are present as a result of the generation of such high fields by currently proposed techniques. It is anticipated that the use of superconducting materials will both permit the attainment of such high fields and further permit such fields to be generated with vastly improved efficiency.

Abstract: A porous layer of catalyst material suitable for use as an electrode in a molten carbonate fuel cell includes elongated pores substantially extending across the layer thickness. The catalyst layer is prepared by depositing particulate catalyst material into polymeric flocking on a substrate surface by a procedure such as tape casting. The loaded substrate is heated in a series of steps with rising temperatures to set the tape, thermally decompose the substrate with flocking and sinter bond the catalyst particles into a porous catalytic layer with elongated pores across its thickness. Employed as an electrode, the elongated pores provide distribution of reactant gas into contact with catalyst particles wetted by molten electrolyte.

Abstract: A method of preparing a porous cathode structure for use in a molten carbonate fuel cell begins by providing a porous integral plaque of sintered nickel oxide particles. The nickel oxide plaque can be obtained by oxidizing a sintered plaque of nickel metal or by compacting and sintering finely divided nickel oxide particles to the desired pore structure. The porous sintered nickel oxide plaque is contacted with a lithium salt for a sufficient time to lithiate the nickel oxide structure and thus enhance its electronic conductivity. The lithiation can be carried out either within an operating fuel cell or prior to assembling the plaque as a cathode within the fuel cell.

Abstract: A device for equalizing the molten electrolyte content throughout the height of a fuel cell stack is disclosed. The device includes a passageway for electrolyte return with electrolyte wettable wicking material in the opposite end portions of the passageway.

The second end portion is placed near the lower, positive end of the stack where electrolyte is depleted. Heating means are provided at the upper portion of the passageway to increase electrolyte vapor pressure in the upper wicking material. The vapor is condensed in the lower passageway portion and conducted as molten electrolyte in the lower wick to the positive end face of the stack. An inlet is provided to inject a modifying gas into the passageway and thereby control the rate of electrolyte return.

In one embodiment, the storage element is a planar, suitably circular disk. In use, the storage element is adapted to be initialized by a modulated laser beam which may be focused on the storage element to temporarily heat particular portions of the element to a temperature in excess of the upper temperature, causing a phase change.

Abstract: An erasable optical read/write data storage system is disclosed. The data storage system utilizes a temperature sensitive data storage disk which includes an optical tuning film and a film of thermochromic phase change material which will change from a first phase to a second phase at temperatures in excess of an upper temperature and back to the first phase at temperatures below a lower temperature. An environmentally controlled chamber is provided to maintain the data storage disk at a selected bias temperature between the lower and upper temperatures to ensure that no unintentional phase change will occur. A thermally controlled support member is utilized to temporarily lower the temperature of the disk to a point below the lower temperature, thereby initializing the disk. A modulated laser beam is then focused on the disk to temporarily heat particular portions of the disk to a temperature in excess of the upper temperature, causing a phase change.

Abstract: A latching system is disclosed for a telescopic boom, and comprises a ladder structure for positionment longitudinally along a side of a smaller boom section, and a latch plate assembly for a pivotal attachment to a large boom section. Bias means is further provided for applying a biasing force tending to move the latch plate into the ladder detent slot, and counter bias means for applying counter bias force to the latch plate. Linkages are adapted to extend between the latch plate and the tensioned chains which actuate the small boom section outward and inward relative to the large boom section, whereby the tension forces within the chains serve to provide counter biasing forces to the latch plate mechanism.
