    摘要： A method of preparing a supported catalyst, the method comprising mixing a first catalytic metal precursor and a first solvent to obtain a first catalytic metal precursor mixture; mixing a carbon support for catalyst and the first catalytic metal precursor mixture, and drying the mixture to obtain a primary supported catalyst precursor; subjecting the primary supported catalyst precursor to a hydrogen reduction heat treatment, to obtain a primary supported catalyst; mixing the primary supported catalyst and a polyhydric alcohol to obtain a primary supported catalyst mixture; mixing a second catalytic metal precursor and a second solvent to obtain a second catalytic metal precursor mixture; mixing the primary supported catalyst mixture and the second catalytic metal precursor mixture to obtain a secondary supported catalyst precursor mixture; and adjusting the pH of the secondary supported catalyst precursor mixture, and then heating the secondary supported catalyst precursor mixture to obtain a supported catalyst, a supported catalyst prepared by the method, an electrode comprising the supported catalyst, and a fuel cell including the electrode are provided. A supported catalyst having a desired amount of loaded catalytic metal particles can be obtained by preparing a primary supported catalyst containing catalytic metal particles that are obtained by a primary gas phase reduction reaction of a portion of the final loading amount of catalytic metal, and reducing the remaining portion of the catalytic metal by a secondary liquid phase reduction reaction. The supported catalyst contains catalytic metal particles having a very small average particle size, which are uniformly distributed on a carbon support at a high concentration, and thus exhibits maximal catalyst activity. A fuel cell produced using the supported catalyst has improved efficiency.

    摘要： A platinum (Pt)/ruthenium (Ru) alloy catalyst, highly resistant to CO poisoning, having a lattice constant of 3.856-3.885 Å and a particle size of 2-5 nm, and supported on a carrier. The Pt/Ru alloy catalyst is highly resistant to CO poisoning, thereby allowing for higher catalytic activity when used. That is, an electrode and a fuel cell having a longer lifetime can be prepared using a smaller amount of the Pt/Ru alloy catalyst.

    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.
