  • Publication number: 20210036335
    Abstract: Corrosion-resistant oxide films for use with proton exchange membrane fuel cells are described. Bipolar plates of proton exchange membrane fuel cells are subject to highly-acidic environments that can degrade the bulk material and associated properties of the bipolar plate leading to reduced proton exchange membrane fuel cell lifetimes. Materials, structures, and techniques for increasing the corrosion resistance of bipolar plates are disclosed. Such materials include substrates having a surface portion, which includes an Fe2O3 oxide layer having (110), (012), or (100) Fe2O3 surface facets configured to impart corrosion-resistance properties to the substrate.

    Abstract: An electrostatic charging air cleaning device having first and second pre-chargers. The first pre-charger is configured to generate a first corona discharge to electrostatically charge PM in the incoming air stream with a first charge to form a first exiting air stream exiting the first pre-charger.

The composition varies over a range with respect to a quantity of chloride ions per formula unit. The power source supplies current to the first electrode in a first operating state so as to induce a reversible conversion reaction in which the conversion material bonds to the chloride ions in the saline water to generate a treated water solution. The conversion material dissociates the chloride ions therefrom into the saline water solution in a second operating state to generate a wastewater solution.

  • Publication number: 20200106105
    Abstract: A method of forming a metal oxy-fluoride surface on lithium metal oxide cathode material particles is disclosed. Such a metal oxy-fluoride surface may help to prevent lithium metal oxide cathode active materials from reacting with water, thus enabling aqueous processing of cathodes made from such materials in the manufacture of lithium batteries. Such a method may also reduce lithium battery manufacturing costs and time by substituting water for currently-used organic solvents that are expensive and require special handling and disposal. Such a method may also reduce the cost of lithium metal oxide cathode active materials as the requirements for moisture-free manufacture, storage, and processing will be reduced or eliminated.
