  • Publication number: 20180323480
    Abstract: A thermogalvanic electrochemical system includes two battery sources connected together in a switchable circuit to provide electric current to an electrical load in the circuit. The battery sources are located in a thermal environment having a varying temperature, and each battery source has a corresponding electrical potential that varies with temperature of the thermal environment. A power management processor operates the circuit to: form a closed circuit at a first temperature with current flow from a first battery source through the electrical load to a second battery source until reaching a first thermal equilibrium, and then form an open circuit, then form a closed circuit at a second temperature with current flow from the second battery source through the electrical load to the first current source until reaching a second thermal equilibrium, and then form an open circuit.

  • Publication number: 20180212275
    Abstract: A class of sulfonimide salts for solid-state electrolytes can be synthesized based on successive SNAr reactions of fluorinated phenyl sulfonimides: Fluorinated Aryl Sulfonimide Tags (FAST). The chemical and electrochemical oxidative stability of these FAST salts as well as other properties like solubility, Lewis basicity, and conductivity can be tuned by introducing different numbers and types of nucleophilic functional groups to the FAST salt scaffold.

  • Publication number: 20180048042
    Abstract: An electrochemical system can include transition metal nanoparticles as a promoter for an electrode. The transition metal nanoparticles can include molybdenum (Mo), chromium (Cr), and/or the oxides thereof, which can lower recharge potentials and enhance the efficiency. These promoters promote especially the generation of oxygen and this for several cycles of usage of the electrochemical system which is, as a result, rechargeable.

    Abstract: Integrated polymeric-ceramic membrane-based oxy-fuel combustor. The combustor includes a polymer membrane structure for receiving air at an input and for delivering oxygen-enriched air at an outlet. An oxygen transport reactor including a ceramic ion transport membrane receives the oxygen-enriched air from the polymer membrane structure to generate oxygen for combustion with a fuel introduced into the oxygen transport reactor.

  • Patent number: 8691464
    Abstract: The present invention relates to single chamber fuel cells and systems and methods associated with the same. Architectures and materials that allow for high performance, enhanced fuel utilization, mechanical robustness, and mechanical flexibility are described. In some embodiments, multiple fuel cell units are arranged in a single chamber and may be, in some cases, connected to each other (e.g., connected in series, connected in parallel, etc.). Each fuel cell unit can be defined as one or more anode(s), one or more cathode(s), and an electrolyte able to maintain electrical separation between the anode(s) and cathode(s). The multiple fuel cell units are arranged in stacks in some cases. In one set of embodiments, the stacks of fuel cell units can be shaped and/or arranged to enhance the mixing of fuel and oxidant, thus improving distribution of reactants in the reaction zone. For example, the stacks of fuel cells may be arranged as fins within the fuel cell chamber.

  • Publication number: 20130020207
    Abstract: The oxygen evolution reaction (OER)-catalyzing activity of transition metal perovskite oxide catalysts depends on the occupancy of the ?-bonding orbital of eg symmetry parentage of the active cation. Catalysts having preferred values of eg orbital filling can have a high intrinsic activity for catalysis of the OER.

  • Publication number: 20110274989
    Abstract: Methods and devices for catalyzing reactions, e.g., in a metal-air electrochemical cell, are disclosed. In some instances, a porous positive electrode of the metal-air electrochemical cell includes a metal to catalyze a reaction at the electrode (e.g., oxidation of one or more metal-oxide species). The metal can be disposed as nanoparticles, and/or be combined with a second metal. Other aspects are directed to devices and methods that can generally promote a chemical reaction (e.g., an oxidation/reduction reaction) such as the formation of platinum containing nanoparticles that can be used to catalyze electrochemical reactions.

  • Publication number: 20100159366
    Abstract: The embodiments described herein relate generally to methods, compositions, articles, and devices associated with layer-by-layer assembly and/or functionalization of carbon-based nanostructures and related structures. In some embodiments, the present invention provides methods for forming an assembly of carbon-based nanostructures on a surface. The carbon-based nanostructure assembly may exhibit enhanced properties, such as improved arrangement of carbon-based nanostructures (e.g., carbon nanotubes) and/or enhanced electronic and/or ionic conductivity and/or other useful features. In some cases, improved properties may be observed due to the attachment of functional groups to the surfaces of carbon-based nanostructures. Using methods described herein, formation of carbon-based nanostructure assemblies may be controlled to produce structures with enhanced properties.

  • Patent number: 7229944
    Abstract: Fiber structures that include a catalytic material are provided. The fiber structures (e.g., membranes) may be formed of interconnected carbon fibers. The catalytic material may be in the form of nanosize particles supported on the fibers. In one method of the invention, the structures are produced by electrospinning a polymeric material fiber structure that is subsequently converted to a carbon fiber structure in a heat treatment step which also causes the catalytic material particles to nucleate on the carbon fibers and grow to a desired size. The catalytic material may be uniformly distributed across the carbon fiber structure and the amount of catalytic material may be controlled. These factors may enhance catalytic performance and/or enable using less catalytic material for equivalent catalytic performance which can lead to cost savings, amongst other advantages. The fiber structures may be used in a variety of applications including electrodes in batteries and fuel cells.
