  • Patent number: 8821968
    Abstract: A method of fabricating a layer-structured catalysts at the electrode/electrolyte interface of a fuel cell is provided. The method includes providing a substrate, depositing an electrolyte layer on the substrate, depositing a catalyst bonding layer to the electrolyte layer, depositing a catalyst layer to the catalyst bonding layer, and depositing a microstructure stabilizing layer to the catalyst layer, where the bonding layer improves adhesion of the catalyst onto the electrolyte. The catalyst and a current collector is a porous catalyst and a fully dense current collector, or a fully dense catalyst and a fully dense current collector structure layer. A nano-island catalyst and current collector structure layer is deposited over the catalyst and current collector or over the bonding layer, which is deposited over the electrolyte layer. The fuel cell can be hydrogen-fueled solid oxide, solid oxide with hydrocarbons, solid sensor, solid acid, polymer electrolyte or direct methanol.

  • Patent number: 8163338
    Abstract: A method of precursor selection for thin film deposition is provided, that includes a group of precursors, using a rule-set for selecting one or more candidate precursors for thermal stability, high growth rate, and low contamination. Candidate geometries and constituent geometries are simulated and optimized, and bond strengths of the candidates and constituents are determined. The rule-set is based on bond strength that compares molecule and constituent energies between a set of bond strengths within a candidate ligand or between a metal atom and one ligand. The rule-set requires metal atom-ligand bonds are between 0.2 and 3 eV, metal atom-ligand bond strengths are less than metal atom-ligand bond strengths of other candidates. The metal atom-ligand bond strength is >T?S, where T is a reaction temperature and ?S is the reaction entropy change and the bond within a ligand, where (ligand bond)>(metal atom and ligand bond).

  • Patent number: 8026014
    Abstract: A reduced cost solid oxide fuel cell having enhanced surface exchange rates and diffusivity of oxide ions is provided. The invention cell includes a first porous electrode and a second porous electrode, where the porous electrodes have a layer of electronically conductive porous non-precious metal, and the porous non-precious metal layer is a gas diffusion layer. The porous electrodes further include at least one atomic layer of catalytic metal deposited on the non-precious metal layer, and an electrolyte layer disposed between the first porous electrode and the second porous electrode. The electrolyte layer includes a first dense ion-conductive doped oxide film layer, and a second dense ion-conductive doped oxide film layer deposited on the first doped oxide film layer, where the catalytic metal layer on the conductive porous non-metal layer enhances surface exchange rates and diffusivity of the oxide ions, thus the material costs of the fuel cell are reduced.

  • Patent number: 7790629
    Abstract: A method of depositing oxide materials on a substrate is provided. A deposition chamber holds the substrate, where the substrate is at a specified temperature, and the chamber has a chamber pressure and wall temperature. A precursor molecule containing a cation material atom is provided to the chamber, where the precursor has a line temperature and a source temperature. An oxidant is provided to the chamber, where the oxidant has a source flow rate. Water is provided to the chamber, where the water has a source temperature. By alternating precursor pulses, the water and the oxidant are integrated with purges of the chamber to provide low contamination levels and high growth rates of oxide material on the substrate, where the pulses and the purge have durations and flow rates. A repeatable growth cycle includes pulsing the precursor, purging the chamber, pulsing the water, pulsing the oxidant, and purging the chamber.

  • Patent number: 7682528
    Abstract: An La2O3 powder and an SiO2 powder are mixed with each other, and then heated. By heating, a porous material of LaXSi6O1.5X+12 (8?X?10) as a composite oxide is produced. Subsequently, the porous material is pulverized to obtain a powder, and the powder is added to a solvent to prepare a slurry. The slurry is solidified in a magnetic field to prepare a compact. After that, the compact is sintered, and an oxide ion conductor is obtained thereby.
