  • Multi-interface membrane electrode assembly
    Patent number: 11616247
    Abstract: A fuel cell membrane electrode assembly having: a proton exchange membrane, an anode catalyst coating on one side of the membrane, and a cathode catalyst coating on the other side of the membrane. The cathode catalyst coating has at least two carbon catalyst layers, with a low porosity layer adjacent to a high porosity layer. The high porosity layers have a volume fraction that is higher than the volume fraction of the low porosity layers.
    Type: Grant
    Filed: June 16, 2021
    Date of Patent: March 28, 2023
    Assignee: The Government of the United States of America, as represented by the Secretary of the Navy
    Inventors: Yannick Garsany, Robert Atkinson, III, Benjamin Gould
