摘要： A low cost, lanthanide-substituted, dimensionally and thermally stable, gas permeable, electrically conductive, porous ceramic air electrode composition of lanthanide-substituted doped lanthanum manganite is provided which is used as the cathode in high temperature, solid oxide electrolyte fuel cells and generators. The air electrode composition of this invention has a much lower fabrication cost as a result of using a lower cost lanthanide mixture, either a natural mixture or an unfinished lanthanide concentrate obtained from a natural mixture subjected to incomplete purification, as the raw material in place of part or all of the higher cost individual lanthanum. The mixed lanthanide primarily contains a mixture of at least La, Ce, Pr, and Nd, or at least La, Ce, Pr, Nd and Sm in its lanthanide content, but can also include minor amounts of other lanthanides and trace impurities. The use of lanthanides in place of some or all of the lanthanum also increases the dimensional stability of the air electrode. This low cost air electrode can be fabricated as a cathode for use in high temperature, solid oxide fuel cells and generators.

摘要： Materials and methods for the fabrication of high density, low temperature fired microwave ferrites for use in microwave power devices, transmission line elements, isolators, circulators, and phase shifters. Very fine (sub-micron) ferrite powders made by sol-gel methods are mixed with solvents and binders then tape-cast. Ferrite tapes in the unfired state are cut into complex shapes and may be provided with via holes. These ferrite sheets are fired discretely, or are laminated, cofired with printed metal pastes, or other active and passive ceramic tapes.

摘要： Methods of preparing ferrite powders for use in microwave elements such as isolators, circulators, phase shifters and transmission line elements. In one method separate precipitations of metal dicarboxylate salts such as oxalates or malonates are mixed with a ferrous dicarboxylate. This is followed by mixing and calcining of the precipitated dicarboxylates to form the ferrite powder. In another method metal acetates in a solution of concentrated acetic acidare mixed with iron powder to form a solution which is mixed with malonic acid. The resulting mixed metal malonates are processed into a powder which is calcined to obtain the ferrite. To form a lithium ferrite, lithium carbonate is added to prepared powders prior to the calcining step.

The control mechanism may control the fuel input and the oxidizer input. The fuel input may utilize a hydrocarbon fuel or, alternatively, an arbitrary mixture of hydrogen and carbon monoxide. The electric motor may have a field excitation current and the control mechanism may further control the field excitation current. Alternatively, an apparatus may power a vehicle, such as a ship or automobile, and may include an electric motor for powering the vehicle, a fuel cell for providing fuel cell power, a turbine-generator for providing turbine-generator power, and a control mechanism. The electric motor may include a motor power input. The fuel cell may include a fuel input, a fuel cell oxidizer input, a thermal exhaust output, and a fuel cell power output. The turbine-generator may include a compressor for pressurizing oxidizer, a generator for producing a generator power output, and a turbine for driving the compressor and the generator. The generator power output may supplement the fuel cell power output in order to produce power for the motor power input. The turbine may have a thermal exhaust input interconnected with the thermal exhaust output of the fuel cell. The compressor may have a compressor oxidizer input and an oxidizer output interconnected with the fuel cell oxidizer input. The control mechanism may control the fuel input, the compressor oxidizer input or the field excitation current.
