摘要： The invention comprises novel undoped and doped nanometer-scale CeO2 particles as well as a novel semi-batch reactor method for directly synthesizing the novel particles at room temperature. The powders exhibited a surface area of approximately 170 m2/g with a particle size of about 3–5 nm, and are formed of single crystal particles that are of uniform size and shape. The particles' surface area could be decreased down to 5 m2/g, which corresponds to a particle size of 100 nm, by thermal annealing at temperatures up to 1000° C. Control over the particle size, size distribution and state of agglomeration could be achieved through variation of the mixing conditions such as the feeding method, stirrer rate, amount of O2 gas that is bubbled through the reactor, the temperature the reaction is carried out at, as well as heating the final product at temperatures ranging from 150° to 1000° C.
摘要翻译：本发明包括新型未掺杂和掺杂的纳米级CeO 2 N 2颗粒，以及用于在室温下直接合成新型颗粒的新型半间歇反应器方法。粉末表现出约170m 2 / g的粒度约3-5nm的表面积，并由均匀尺寸和形状的单晶颗粒形成。通过在高达1000℃的温度下进行热退火，可将颗粒的表面积降低至5m 2 / g，这对应于100nm的粒度。对于粒度，尺寸分布和附聚状态可以通过改变混合条件来实现，例如进料方法，搅拌器速率，鼓泡通过反应器的O 2 N 2气体的量，进行反应的温度并在150°-1000℃的温度范围内加热最终产品。

摘要： A method for forming electrical connections between parts of a fuel cell that includes subjecting a contact paste positioned between the parts to alternating flows of gasses having varying high and low partial pressures of oxygen. This method demonstrates the ability to form conductive interconnections that have sufficient mechanical stability because these pastes can be cured at a temperature less than the temperatures of the surrounding materials thus allowing desired portions to be cured while allowing other portions such as the glass or ceramic portions to maintain their desired mechanical and electrical properties.

摘要： Solid-state ionic or electrochemical devices can depend critically on the proper formation of a dense, Gd-doped ceria (GDC) layer on a porous substrate. Devices and methods of the present invention are characterized by the formation of a transitional buffer layer, which is less than 10 microns thick and comprises GDC, located between the porous substrate and the dense GDC layer. The transitional buffer layer provides a practical way to form the dense GDC layer on the porous substrate without cracks in the GDC layer and without clogging the pores of the substrate.
