  • Membrane electrode assembly for fuel cell having catalyst layer with mesopore volume, method of preparing same, and fuel cell system including the same
    Patent number: 8445163
    Abstract: The membrane-electrode assembly for a fuel cell includes an anode and a cathode facing each other and a polymer electrolyte membrane interposed therebetween. The cathode includes an electrode substrate and a catalyst layer disposed on the electrode substrate, and the catalyst layer has a mesopore volume ranging from 0.013 to 0.04 cm3/g. The membrane-electrode assembly has low mass resistance and contributes to the overall increased performance of the fuel cell by having optimal pore volumes (e.g., mesopore volume) in a cathode catalyst layer to provide ease of transfer and release of materials within the membrane-electrode assembly of the fuel cell.
    Type: Grant

  • Membrane electrode assembly for fuel cell, and fuel cell system including the same
    Patent number: 8278012
    Abstract: A membrane-electrode assembly for a fuel cell, which includes an anode and a cathode facing each other; and a polymer electrolyte membrane disposed between the anode and cathode. The cathode includes a first catalyst layer that includes catalyst particles, and a second catalyst layer that includes the catalyst particles and a pore-forming agent. The membrane-electrode assembly efficiently performs mass transfer and release, due to pores in the second catalyst layer.
