Patents by Inventor Drew C. HIGGINS

Drew C. HIGGINS 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).

  • Electrochemical catalysts with enhanced catalytic activity
    Patent number: 11973233
    Abstract: A catalyst structure includes: (1) a substrate; (2) a catalyst layer on the substrate; and (3) an adhesion layer disposed between the substrate and the catalyst layer. In some implementations, an average thickness of the adhesion layer is about 1 nm or less. In some implementations, a material of the catalyst layer at least partially extends into a region of the adhesion layer. In some implementations, the catalyst layer is characterized by a lattice strain imparted by the adhesion layer.
    Type: Grant

  • Ultrathin electrochemical catalysts on catalyst support for proton exchange membrane fuel cells
    Patent number: 11955646
    Abstract: A supported catalyst includes: (1) a catalyst support; and (2) deposits of a catalyst covering the catalyst support, wherein the deposits have an average thickness of about 2 nm or less, and the deposits are spaced apart from one another.
