摘要： A thin film capacitor and methods for forming the same are described. The capacitor has dielectric layer with a first face, a second face, and at least one edge. The first terminal of the capacitor covers at least a portion of the first face of the dielectric layer, covers at least a portion of one edge of the dielectric layer, and covers a portion of the second face of the dielectric layer. The second terminal of the capacitor covers a portion of the second face of the dielectric layer and does not contact the first terminal. A method for forming the thin film capacitor includes hard baking photoresist at an elevated temperature and anodizing an exposed metal area using the photoresist as a mask.

摘要： A high performance electrocatalyst is based on transition metal perovskites of praseodymium, samarium, terbium or neodymium which react with YSZ to form a product which is itself active as the cathode in a fuel cell. While PrCoO3 reacts with YSZ, the reaction product(s) do not result in severe degradation of cell performance. A fuel cell made with a cathode composed of only the reaction product of YSZ and PrCoO3 has good performance, indicating that this phase is itself not only a good conductor, but also a good catalyst for oxygen activation.
摘要翻译：高性能电催化剂是基于镨，钐，铽或钕的过渡金属钙钛矿，它们与YSZ反应形成一种本身作为燃料电池阴极活性的产物。当PrCoO 3与YSZ反应时，反应产物不会导致电池性能的严重劣化。由仅由YSZ和PrCoO3的反应产物组成的阴极制成的燃料电池具有良好的性能，表明该相本身不仅是良好的导体，而且也是氧活化的良好催化剂。

摘要： A planar solid oxide fuel cell stack has a number of fuel cells (anode/electrolyte/cathode) connected in series by a gas tight, electrically conductive interconnection in which at least one electrode is a porous composite of a contiguous network of an ionically conductive material or phase, a contiguous network of an electrically conductive material or phase, and a highly efficient electrocatalyst material or phase which is dispersed within the pores of the electrode so that the electrocatalyst material or phase particles are in contact with both the ionically conductive material or phase and the electrically conductive material or phase. The electrocatalyst particles are introduced into the electrode of the assembled stack by infiltrating the pores of the electrode with a precursor solution through the fuel gas or oxidant gas manifolding connections, respectively. The stack assembly is then heat treated to form small, highly active particles of the dispersed electrocatalyst material or phase within the electrode.

摘要： Subject a heated, non-molten, intimate admixture of a base metal and a superconducting oxide material to pressure sufficient to form a densified article. The densified article is either superconducting as formed or capable of being rendered superconducting by annealing in the presence of oxygen. Depending upon the choice of materials the densified article is stable at temperatures up to 1000.degree. C.
