Julien Cellier 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).

  • Proton-conducting inorganic particles, method for the preparation thereof, and use thereof to form a fuel cell membrane
    Patent number: 11180620
    Abstract: The invention relates to inorganic particles which are covalently bonded to first polymer chains made up of at least one polymer carrying proton exchange groups, optionally in the form of salts, and bonded to second polymer chains made up of at least one fluorinated polymer that does not carry any proton exchange groups, the second chains being bonded to the particles via organic spacer groups, or the second chains being bonded to first chains via organic spacer groups, or some of the second chains being bonded to the particles via organic spacer groups while the remaining second chains are bonded to first chains via organic spacer groups.
    Type: Grant
    Filed: January 24, 2018
    Date of Patent: November 23, 2021
    Assignees: COMMISSARIAT À L'ÉNERGIE ATOMIQUE ET AUX ÉNERGIES ALTERNATIVES, SPECIFIC POLYMERS
    Inventors: Pierrick Buvat, Janick Bigarré, Julien Cellier, Cédric Loubat, Quentin Crouzet
  • Fluorinated proton-conducting inorganic particles and use of said particles in proton-conducting membranes
    Patent number: 11124592
    Abstract: Silica particles bonded to polymer chains consisting of at least one polymer comprising at least one fluorinated styrene repeating unit comprising at least one proton-conducting group, optionally in the form of a salt, the bonding between the particles and each of the chains being carried out by an organic spacer group.
