    摘要： Provided are a supported catalyst, an electrode including the same, and a fuel cell using the electrode. The supported catalyst includes a carbon-based catalyst support and metal catalyst particles having an average diameter of 3.5 to 5 nm and an amount of 80 to 90 parts by weight based on 100 parts by weight of the supported catalyst in a multi-layer structure adsorbed on a surface of the carbon-based catalyst support. In the supported catalyst of the present invention, as small metal catalyst particles with an average diameter of 3.5 to 5 nm are dispersed with high concentration, high dispersion, and the multi-layer structure, catalytic efficiency is increased. A fuel cell having improved energy density and fuel efficiency characteristics can be prepared using an electrode formed using the supported catalyst.

    摘要： A method of preparing a mesoporous carbon includes mixing a mesophase pitch, a carbon precursor, an acid, and a solvent to obtain a carbon precursor mixture; impregnating an ordered mesoporous silica (OMS) with the carbon precursor mixture; heat-treating and carbonizing the impregnated OMS to form an OMS-carbon composite; and removing the OMS from the OMS-carbon composite. The mesoporous carbon uses the mesophase pitch and the carbon precursor to reduce sheet resistance, and thus can efficiently transfer electric energy. Such mesoporous carbon can be used as a conductive material of electrodes for fuel cells. When the mesoporous carbon is used as a support for catalysts of electrodes, a supported catalyst containing the support can be used to manufacture a fuel cell having high efficiency.

    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： 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.

    摘要翻译： 本发明涉及一种负载在导电性碳载体中的具有Pt或Pt合金的高负载量的碳催化剂。 具体地说，在碳载体催化剂中，负载的Pt或Pt合金的负载量为约50％至约60％（重量），平均粒度为约1nm至约3nm，总比表面积 碳载体催化剂的面积大于约200m 2 / g。 碳载体催化剂可以改善燃料电池的性能，因为催化金属颗粒具有小尺寸和高分散度。 此外，即使在高负载下也可以制备具有均匀分散的非常细的催化剂颗粒的碳载体催化剂。
