Guillaume Krosnicki 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).

  • Fuel cell comprising a proton-exchange membrane, having an increased service life
    Patent number: 9735442
    Abstract: A fuel cell includes a proton-exchange membrane, and a cathode and anode fixed on its opposite sides. The anode delimits a flow conduit between a molecular-oxygen inlet area and a water outlet area. The cathode includes a support for catalyst material. The support has first and second materials to which catalyst is fixed, the first material being a graphitized material. The second material has a resistance to corrosion by oxygen that is greater than that of the first material. A quantity of the second material at the inlet area is greater than a quantity of the second material at the water outlet. The cathode comprises a first layer including the first material and a second layer including the second material. A thickness of the second layer decreases between the molecular-oxygen inlet area and the water outlet area.
    Type: Grant

  • Electrochemical reactor and active layer integrated into said reactor
    Patent number: 9299992
    Abstract: The invention concerns an active layer for an electrochemical reactor comprising:—a carbon electronic conductor which is not a fullerene as a support; and —a catalytic system made up of one or more metals and a fullerene. It also concerns an electrochemical reactor integrating such an active layer.
