    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 method for preparing a slurry for forming a catalyst layer of a PEM fuel cell electrode and a method for fabricating the PEM fuel cell produced thereby are provided. The method for preparing a slurry for forming a catalyst layer of a proton exchange membrane (PEM) fuel cell according to the present invention comprises the steps of (a) adding an MOH solution to a perfluorosulfonate ionomer (PFSI) solution to convert PFSI in the PFSI solution into an M+ form-PFSI solution, wherein M is an alkaline metal selected from the group consisting of Li, Na and K; (b) adding an organic polar solvent having a higher boiling point than that of alcohol remaining in the PFSI solution to a mixed solution obtained in step (a) and heating the mixture at a temperature range of the boiling point of the alcohol to 20° C. higher than the boiling point to remove the remaining alcohol to obtain a pretreated PFSI solution; and (c) mixing the pretreated PFSI solution with Pt/C to form a slurry for forming a catalyst layer of a PEM fuel cell. Since processing stability is improved and the slurry can be easily prepared, Pt loading greater than a conventional level can be achieved by a single coating step by preventing a Pt catalyst from penetrating into a backing layer, the electrode characteristics are improved. Also, mass production of the PEM fuel cells is possible.

    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. When such a supported catalyst is used in a fuel cell, supply of fuel and transporting of byproducts are facilitated.
