摘要： The invention provides and a highly-dispersed supported catalyst that has a reduced average particle size of catalytic metal particles and is also supported by a porous support material. A method of preparing a supported catalyst that can reduce the average particle size of catalytic metal particles supported by a support material includes first mixing a charged support material with a solution containing a polymer electrolyte having a charge opposite to that of the support material to adsorb the polymer electrolyte on the support material. Next, the support material having the polymer electrolyte adsorbed thereon is mixed with a solution containing a catalytic metal precursor ion having a charge opposite to that of the polymer electrolyte to adsorb the catalytic metal precursor ion on the support material having the polymer electrolyte adsorbed on it. Finally, the catalytic metal precursor ion adsorbed on the support material having the polymer electrolyte adsorbed thereon is reduced to a catalytic metal in a reducing solution.

摘要： A membrane electrode assembly for a fuel cell provides a current collector adjacent to an electrode catalyst layer. Since electrons passing between the current collector and the electrode catalyst layer do not pass through a diffusion layer or a supporting layer, the diffusion layer or supporting layer may be non-conductive. Thus, various materials that are hydrophilic, hydrophobic, porous, hydrous, or the like can be used for the diffusion layer and the supporting layer, thereby improving the performance of the fuel cell. In addition, manufacturing costs of the membrane electrode assembly can be decreased since the membrane electrode assembly can be manufactured quickly with low energy.
