Vincent L. Sprenkle 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).

  • Thin film modular electrochemical product and method of manufacture thereof
    Publication number: 20020060148
    Abstract: A method of manufacturing a thin film electrochemical apparatus is disclosed. A near net shape ceramic element is molded including a planar base region and a plurality of tubular regions. The planar base region is infiltrated with a non-conductive material. Each of the tubular regions is infiltrated with a porous conductive material. A porous catalytic electrode material is applied onto the infiltrated regions to form one of a cathodic and anodic surface. A ceramic electrolyte coating is deposited onto the porous catalytic electrode material. A porous catalytic electrode material is applied onto the deposited ceramic electrolyte coating. A porous conductive material is deposited onto the porous catalytic electrode to form the other of the cathodic and anodic surface.
    Type: Application

  • Electrochemical oxygen generating system
    Patent number: 6352624
    Abstract: This invention relates to devices for separating oxygen from more complex gasses such as air which contains oxygen, and delivering the separated-oxygen at an elevated pressure for use immediately, or for storage and use later. More particularly, the invention relates to solid state electrochemical devices for separating oxygen from more complex gasses to produce the desired oxygen and delivering the oxygen at elevated pressures up to and exceeding 2000 psig.
