  • Membrane electrode assembly (MEA) for proton exchange membrane electrochemical cell
    Patent number: 11973231
    Abstract: A membrane electrode assembly (MEA) includes an ionically-conductive proton exchange membrane. Further, the MEA includes an anode contacting a first side of the membrane. The anode includes an anode gas diffusion layer (GDL). Further, the anode includes a first anode catalyst layer containing first catalyst particles, a hydrophobic polymer bonding agent, and a first ionomer bonding agent that lacks functional chains on a molecular backbone. The anode also includes a second anode catalyst layer containing second catalyst particles and a second ionomer bonding agent that includes functional chains on a molecular backbone. The MEA also includes a cathode contacting a second side of the membrane and comprising third catalyst particles and a cathode GDL.
    Type: Grant
