Gordon Rice 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).

  • Patent number: 9975775
    Abstract: The invention is directed to high surface area graphitized carbon and to processes for making high surface area graphitized carbon. The process includes steps of graphitizing and increasing the surface area of (in either order) a starting carbon material to form high surface area graphitized carbon. The step of increasing the surface area optionally comprises an oxidizing step (e.g., through steam etching) or template removal from composite particles. The invention is also directed to catalyst particles and electrodes employing catalyst particles that are formed from the high surface area graphitized carbon.
    Type: Grant

  • Patent number: 7906453
    Abstract: Processes for forming catalyst particles utilizing a defoamer are described. Also described are processes for forming catalysts, where the processes comprise providing a correlation between defoamer concentration and catalyst particle morphology, and determining an amount of defoamer to include in a precursor composition to obtain the target morphology based on the correlation.

  • Publication number: 20060292434
    Abstract: Compositions and methods for the manufacture of electrodes for fuel cells. The compositions and methods are particularly useful for the manufacture of anodes and cathodes for proton exchange membrane fuel cells, particularly direct methanol fuel cells. The methods can utilize direct-write tools to deposit ink compositions and form functional layers of a membrane electrode assembly having controlled properties and enhanced performance.
