    摘要: A fuel cell stack induces smooth current collection and liquid or gas flow without using a heavy bipolar plate. The fuel cell stack includes: a membrane and electrode assembly (MEA) in which an electrolyte membrane is disposed between a cathode electrode and an anode electrode; a current collector disposed in the MEA to form an electrical path with an adjacent MEA; and a non-conductive separation plate disposed between the MEA and the adjacent MEA, the non-conductive separation plate forming flow channels to supply a liquid or gas to the cathode electrode and the anode electrode. A fuel cell stack structure having the above structure is simple and lightweight as the MEA includes a thin and lightweight non-conductive polymer separation plate and a current collector to connect adjacent MEAs.

    摘要: A catalyst coated membrane (CCM) comprising an anode catalyst layer having a first catalyst layer composed of a non-supported catalyst and a second catalyst layer composed of a supported catalyst, a cathode catalyst layer composed of a supported catalyst, and an electrolyte membrane interposed between the anode catalyst layer and a cathode catalyst layer, the first catalyst layer of the anode catalyst layer being disposed adjacent to the electrolyte membrane; a membrane electrode assembly (MEA) comprising the catalyst coated membrane; a method of preparing the membrane electrode assembly; and a fuel cell comprising the membrane electrode assembly, are provided. The CCM, which comprises a bilayered anode catalyst layer including the first catalyst layer composed of a non-supported catalyst and the second catalyst layer composed of a supported catalyst, exhibits reduced electrical resistance and interfacial resistance, and has increased catalyst availability. The use of the CCM and an MEA having the same results in a decrease in the interfacial resistance between the electrodes and the electrolyte membrane, a decrease in the amount of the catalyst used in the electrode catalyst layer, and a decrease in the thickness deviation in the electrode layers. The fuel cell employing the MEA exhibits maximal activity of the supported catalyst, and has improved cell characteristics such as output voltage, output density, efficiency, and the like.

    摘要: A mesoporous carbon composite includes mesoporous carbon having mesopores; a conductive polymer coated on only an outer surface of the mesoporous carbon; and an organic electrolyte comprising a lithium salt and an organic solvent. The mesoporous carbon composite may be prepared by impregnating an ordered mesoporous silica (OMS) with a carbon precursor mixture comprising a carbon precursor, an acid, and a solvent; heat-treating and carbonizing the impregnated OMS to form an OMS-carbon composite; mixing the OMS-carbon composite with a monomer that forms a conductive polymer and a solvent to provide a surface of the OMS-carbon composite with the monomer that forms a conductive polymer; polymerizing the monomer to obtain a conductive polymer-coated OMS-carbon composite; removing the OMS from the conductive polymer-coated OMS-carbon composite to obtain a conductive polymer-coated mesoporous carbon; and doping the conductive polymer-coated mesoporous carbon with an organic electrolyte comprising a lithium salt and an organic solvent to form the mesoporous carbon composite. A supported catalyst contains the mesoporous carbon composite, and a fuel cell uses an electrode containing the mesoporous carbon composite.

    摘要: The present invention is related to a high loading supported carbon catalyst having Pt or a Pt alloy supported into an electrically conductive carbon support. Specifically, in the carbon supported catalyst, a loading of the supported Pt or Pt alloy is in the range of about 50% to about 60% by weight, an average particle size is about 1 nm to about 3 nm, and a total specific surface area of the carbon supported catalyst is greater than about 200 m2/g. The carbon supported catalyst may improve the performance of a fuel cell because the catalytic metal particles have a small size and a high degree of dispersion. Also, a carbon supported catalyst having very fine catalyst particles uniformly dispersed may be prepared even at a high loading may be prepared.
