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 method of preparing a supported catalyst includes dissolving a cation exchange polymer in alcohol to prepare a solution containing cation exchange polymer; mixing the cation exchange polymer containing solution with a catalytic metal precursor or a solution containing catalytic metal precursor; heating the mixture after adjusting its pH to a predetermined range; adding a reducing agent to the resultant and stirring the solution to reduce the catalytic metal precursor; mixing the resultant with a catalyst support; adding a precipitating agent to the resultant to form precipitates; and filtering and drying the precipitates. The method of preparing a supported catalyst can provide a highly dispersed supported catalyst containing catalytic metal particles with a reduced average size regardless of the type of catalyst support, which provides better catalytic activity than conventional catalysts at the same loading amount of catalytic metal.

摘要： A sulfur-containing mesoporous carbon that has mesopores with an average diameter of 2 to 10 nm, a method of preparing the same, a catalyst containing the mesoporous carbon as a catalyst support, and a fuel cell using the catalyst in which the sulfur-containing mesoporous carbon has a good affinity for and adhesion to catalyst particles so as to strongly support the catalyst particles due to the sulfur atoms substituting for carbons in an OMC carbon skeleton structure. The growth of metal catalyst particles is prevented when heat-treating the metal catalyst particles. The catalyst using the sulfur-containing mesoporous carbon can be applied to a fuel cell to prevent a reduction in catalytic activity due to increased particle size by an accumulation of catalyst particles. The catalyst containing the sulfur-containing mesoporous carbon as a catalyst support can be used to manufacture a fuel cell having an improved performance.
