    Abstract: The materials and processes for forming fuel cell electrodes can include substrates of codeposited materials including an electrically conductive material, such as graphite, a polymer film, such as a proton-exchange membrane, and a catalytic material, such as platinum. The material may be applied to a polymer film by combustion chemical vapor deposition (CCVD) to produce a layered membrane, or the polymer may be deposited simultaneously with the catalytic coating to produce a membrane wherein the layers are intermingled. Proton exchange membranes prepared by this method are useful in the manufacture of fuel cells.

    Abstract: Epitaxial thin films for use as buffer layers for high temperature superconductors, electrolytes in solid oxide fuel cells (SOFC), gas separation membranes or dielectric material in electronic devices, are disclosed. By using CCVD, CACVD or any other suitable deposition process, epitaxial films having pore-free, ideal grain boundaries, and dense structure can be formed. Several different types of materials are disclosed for use as buffer layers in high temperature superconductors. In addition, the use of epitaxial thin films for electrolytes and electrode formation in SOFCs results in densification for pore-free and ideal grain boundary/interface microstructure. Gas separation membranes for the production of oxygen and hydrogen are also disclosed. These semipermeable membranes are formed by high-quality, dense, gas-tight, pinhole free sub-micro scale layers of mixed-conducting oxides on porous ceramic substrates. Epitaxial thin films as dielectric material in capacitors are also taught herein. Capacitors are utilized according to their capacitance values which are dependent on their physical structure and dielectric permittivity. The epitaxial thin films of the current invention form low-loss dielectric layers with extremely high permittivity. This high permittivity allows for the formation of capacitors that can have their capacitance adjusted by applying a DC bias between their electrodes.

    Abstract: Apparatus is described for rapidly coating a large area, or for rapidly producing a powder. In one embodiment, a liquid having a coating chemical is pumped from a liquid reservoir to a distribution manifold. From the distribution manifold, the liquid is carried under pressure to a geometric array, e.g., linear, of atomization nozzles. Flow equalization means are provided for equalizing the flow of the liquid delivered to each nozzle, and, preferably, means are provided for equalizing the temperature of the liquid delivered to each nozzle. The liquid, upon exiting the nozzles with the attendant pressure drop atomizes. The atomized liquid coats a substrate either in non-reacted or reacted form, or forms a powder. In a preferred embodiment, a solution of precursor chemical is reacted in a geometric array of flames produced at the nozzles, and a coating material produced in the flame coats the substrate, or a powder is formed. In another embodiment, vaporized precursor and vaporized are fed to a burner chamber having a linear exit slit. The vapor exiting the slit is burned, and material produced in a flame reaction are deposited on a substrate, or the powder formed is collected.
