Patents by Inventor David C. Erbaugh

David C. Erbaugh 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: 9598782
    Abstract: A membrane module and method of making are provided. Exemplarily, the membrane module is adapted for use with an electrochemical apparatus. The membrane comprises a fabric made from a synthetic fiber such as nylon, where the nylon is woven into ripstop nylon fabric. The membrane module includes the membrane around which is formed a frame, comprising exemplarily, high-density polyethylene (HDPE) or polypropylene, which frame provides support to the membrane as well as support and structure to internal electrodes.
    Type: Grant
    Filed: January 26, 2015
    Date of Patent: March 21, 2017
    Inventors: Christopher M. McWhinney, David C. Erbaugh

  • Patent number: 8940152
    Abstract: A process is provided for producing electrolytic decomposition products of water by effecting a DC potential across a membrane comprising ripstop nylon interposed between an anode and a cathode. In electrolyzer mode, the electrochemical process produces hydrogen as well as oxygen products. In fuel-cell mode, the electrochemical process produces electricity from hydrogen and oxygen.

  • Patent number: 8465629
    Abstract: A membrane for use with an electrochemical apparatus is provided. The electrochemical apparatus may include a fuel cell or electrolyzer, for example, an electrolyzer adapted to produce hydrogen. The membrane comprises a fabric made from a synthetic fiber such as nylon where the nylon, in an exemplary embodiment, is woven into ripstop nylon fabric. The electrochemical apparatus is constructed with frames comprising high-density polyethylene (HDPE) which provide support and structure to the membranes as well as to internal electrodes. A method of making an electrochemical apparatus, such as an electrolyzer, containing a membrane comprising ripstop nylon is also disclosed, as is a method for producing hydrogen gas with an electrolyzer containing a membrane comprising ripstop nylon.
