  • Publication number: 20190360111
    Abstract: Some examples of a method for manufacturing an electrode material for electrolytic hydrogen generation are described. Tungsten salt and nickel salt are mixed in a determined molar ratio on a carbon support by effectively controlling synthesis temperature and composition. Water and adsorbed oxygen, produced by mixing the tungsten salt and nickel salt are removed. Then, methane gas is flowed over the mixture resulting in the electrode material. The electrode material is suitable for use as a catalyst in electrolytic hydrogen generation processes, for example, at an industrial scale, to produce large quantities of hydrogen.

  • Publication number: 20190287734
    Abstract: Disclosed is a method of enhancing thermodynamic stability of a hybrid organic inorganic perovskite through a partial fluorination of CH3NH3+ cation. The method identifies that optimal stability of perovskite material can be reached with low controlled concentration of modified fluorinated cations, which has a tendency to stabilize the material due to the strengthening of some initially weak hydrogen bonds between MA+ cations and surrounding lead-iodide framework. Fluorination also reduces significantly the iodine vacancy mediated diffusion in the perovskite under applied bias voltage.

  • Publication number: 20190148804
    Abstract: The hybrid air-slurry flow cell battery is at least one flow cell having a core area having an anode, a cathode parallel to the anode, and an ion-selective membrane disposed between the anode and the cathode to define parallel anolyte and catholyte flow paths through the core area on opposite sides of the membrane. An electrolyte tank is connected to the input and output of one of the flow paths to circulate a slurry containing a first electrochemically active redox reactant adsorbed on carbon particles suspended in a solvent between the electrolyte tank and the flow path through the core area. A gas diffusion electrode is connected to the other flow path, the gas (preferably air or oxygen) including a second electrochemically active redox reactant forming a redox couple with the first. A redox reaction across the membrane generates a voltage differential between the electrodes.

  • Patent number: 9252431
    Abstract: A fuel cell supported catalyst includes an underlying support structure having at least one of a metal oxide and a metal phosphate. Catalyst particles are arranged onto and in engagement with the support structure. An intermediate conductive, corrosion-resistant layer, such as boron-doped-diamond, is arranged onto and in engagement with the support structure to surround the catalyst particles. The supported catalyst is produced by depositing the intermediate layer onto the support structure after the catalyst particles have been deposited on the underlying support structure, in one example. In another example, voids are provided in the intermediate layer, which has been deposited onto the underlying support structure, to subsequently receive the catalyst particles.

  • Patent number: 8557485
    Abstract: The incorporation of tungsten-containing hydrogen spillover materials into a composite fuel cell anode can be helpful in preserving the carbon catalyst support materials in the fuel cell cathode during periods of hydrogen starvation. Preferred examples of such tungsten-containing hydrogen spillover materials are tungsten oxides and tungsten silicides. These materials, when physically mixed with catalyst-loaded carbon support particles in a composite anode, have shown the ability to promote hydrogen storage in amounts that, during a disruption of hydrogen gas flow, can postpone an anodic potential excursion into the oxygen evolution region for a period of at least several seconds.
