Patents by Inventor Filiberto Clara

Filiberto Clara 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).

  • Electrode and interconnect for miniature fuel cells using direct methanol feed
    Patent number: 6756145
    Abstract: An improved system for interconnects in a fuel cell. In one embodiment, the membranes are located in parallel with one another, and current flow between them is facilitated by interconnects. In another embodiment, all of the current flow is through the interconnects which are located on the membranes. The interconnects are located between two electrodes.
    Type: Grant
    Filed: November 26, 2001
    Date of Patent: June 29, 2004
    Assignee: California Institute of Technology
    Inventors: Sekharipuram R. Narayanan, Thomas I. Valdez, Filiberto Clara
  • Reduced size fuel cell for portable applications
    Patent number: 6680139
    Abstract: A flat pack type fuel cell includes a plurality of membrane electrode assemblies. Each membrane electrode assembly is formed of an anode, an electrolyte, and an cathode with appropriate catalysts thereon. The anode is directly into contact with fuel via a wicking element. The fuel reservoir may extend along the same axis as the membrane electrode assemblies, so that fuel can be applied to each of the anodes. Each of the fuel cell elements is interconnected together to provide the voltage outputs in series.
