  • Patent number: 8993472
    Abstract: Layered catalyst structures for fuel cells, particularly for a Proton Exchange Membrane Fuel Cell (PEMFC), are produced by a reactive spray deposition technology process. The catalyst layers so produced contain particles sized between 1 and 15 nm and clusters of such particles of a catalyst selected from the group consisting of platinum, platinum alloys with transition metals, mixtures thereof and non-noble metals. The catalyst layers without an electrically conducting supporting medium exhibit dendritic microstructure, providing high electrochemically active surface area and electron conductivity at ultra-low catalyst loading. The catalyst layers deposited on an electrically conducting medium, such as carbon, exhibit three-dimensional functional grading, which provides efficient utilization as a catalyst, high PEMFC performance at the low catalyst loading, and minimized limitations caused by reactant diffusion and activation. The catalytic layers may be produced by a single-run deposition method.

  • Publication number: 20140349843
    Abstract: Methods for forming novel fuel cell catalysts are described. The catalyst has a physical structure that is the inverse image of a plurality of hierarchically structured sacrificial support particles. The particles may be formed independently and then infused with one or more transitional metallic salts and nitrogen carbon precursors, or the sacrificial support precursors, transitional metallic salts, and nitrogen carbon precursors may all be combined in such a way that a hierarchically structured sacrificial support with the infused transitional metallic salts and nitrogen carbon precursors is formed in a single step. The infused sacrificial support is then pyrolized, at least once, and the sacrificial support is removed, resulting in the catalyst.

  • Publication number: 20140323292
    Abstract: Provided is a method for making a supported metal catalyst. The method includes forming a mixture comprising a high surface area support, a reducing agent precursor that decomposes to produce reducing gases below about 1200° C., and a metal catalyst precursor. The mixture is heated to a temperature sufficient to decompose the reducing agent precursor to produce a reducing agent, and then cooled to form the supported metal catalyst.

  • Publication number: 20140302407
    Abstract: This invention proposes metal complexes of polyphenylenediamines as the precursors of carbonized materials used as air electrode catalysts. Method of production includes mixing phenylenediamine monomer with a catalyst carrier in a solvent and adding an oxidant with metal salt to produce a metal complex of polyphenylenediamine. After drying the precursor is heat treated in the temperature range 400° C.-1000° C.° in nitrogen. Then the catalyst is leached and heat treated once again. In a modified procedure the heat treatment is carried out in air while leaching and subsequent thermal treatment are eliminated. The catalyst has demonstrated high performance and stability as the component of the air electrode of a metal-air battery.
