Patents by Inventor Yuriy Tolmachev

Yuriy Tolmachev has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Nanostructured core-shell electrocatalysts for fuel cells
    Publication number: 20070105005
    Abstract: Catalytic layers for use in the electrodes of fuel cells including a non-noble metal substrate layer coated with one or a few monolayers of noble metal, such as Pt. These thin, highly porous structures with large catalytically active surface areas, should exhibit a significantly higher power output per mg of Pt and per cm2 of the membrane than the current Polymer Electrolyte Fuel Cells catalytic layers.
