摘要： A desulfurizer for fuel gas for a fuel cell includes: a first adsorption tank including an adsorber having selective adsorption capacity for a thiophene-based compound and a second adsorption tank including an adsorber having selective adsorption capacity for a mercaptan-based compound. The desulfurizer uses separate adsorbers having selective adsorption capacity for a thiophene-based compound and a mercaptan-based compound, in multiple stages to perform a more efficient and economical desulfurizing of a fuel gas to remove various sulfur compounds, especially thiophene-based compounds and mercaptan-based compounds compared to a desulfurizer using a single adsorber.

摘要： Carbon nanotubes have an R value of at least 1.3, where R is defined as the ratio (ID/IG) of an integral value of D band intensity (ID) to an integral value of G band intensity (IG) in the Raman spectrum. Such carbon nanotubes can be used to form a support catalyst with good catalyst activity because the surface defects on the carbon nanotubes promote improved catalyst distribution in that the support catalyst includes catalyst particles having a small mean particle size and a slight variation in particle size. Such a support catalyst has particularly useful properties when used as a catalyst layer for a fuel cell electrode.

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.

摘要： Carbon nanotubes for use in a fuel cell, a method for fabricating the same, and a fuel cell using the carbon nanotubes for its electrode are provided. The internal and external walls of the carbon nanotubes are doped with nano-sized metallic catalyst particles uniformly to a degree of 0.3-5 mg/cm2. The carbon nanotubes are grown over a carbon substrate using chemical vapor deposition or plasma enhanced chemical vapor deposition. Since the carbon nanotubes have a large specific surface area, and metallic catalyst particles are uniformly distributed over the internal and external walls thereof, the reaction efficiency in an electrode becomes maximal when the carbon nanotubes are used for the electrode of a fuel cell. The carbon nanotubes fabricated using the method can be applied to form a large electrode. The carbon nanotubes grown over the carbon substrate can be readily applied to an electrode of a fuel cell, providing economical advantages and simplifying the overall electrode manufacturing process. A fuel cell using as the carbon nanotubes for its electrode provides improved performance.

摘要： A hierarchical mesoporous carbon is provided in which a total volume of mesopores of the hierarchical mesoporous carbon is 80% or greater of a total volume of pores of the hierarchical mesoporous carbon; a volume of mesopores with a average diameter greater than 20 nm and no greater than 50 nm is 3% or greater of the total volume of the pores; and a volume of mesopores with a average diameter greater than 2 nm and no greater than 10 nm is 65% or greater of the total volume of the pores. The hierarchical mesoporous carbon, which also contains macropores, has an optimized mesoporous distribution characteristic, and has an increased total volume of pores, thereby having a significantly improved catalytic activity when used as a catalyst support.
