    摘要： A method for preparing a metal catalyst includes a proton conductive material coating layer formed on the surface of a conductive material. Also, an electrode may be prepared using the metal catalyst. The method for preparing the metal catalyst comprises mixing the conductive catalyst material, the proton conductive material, and a first solvent, casting the mixture onto a supporting layer and drying the mixture to form a conductive catalyst containing film. The method further comprises separating the conductive catalyst containing film from the supporting layer and pulverizing the conductive catalyst containing film to obtain the metal catalyst. The method for preparing the electrode comprises mixing the metal catalyst with a hydrophobic binder and a second solvent, coating the mixture on an electrode support, and drying it.

    摘要： A binder for an electrode of a fuel cell is a basic polymer including a nitrogen-containing functional group and a proton conductive polymer having a phosphoric acid impregnation capacity of 200 wt % or less. An electrode for a fuel cell includes the binder and a catalyst, and a fuel cell includes the electrode. The electrode is manufactured by mixing the binder, a catalyst, and a solvent; and coating the mixture on a carbon support and heat-treating the coated mixture. The binder has excellent proton conductivity by having a phosphoric acid impregnation capacity of 200 wt % or less, and has improved durability without membrane damage and micro-structural changes due to swelling, which occurs when PBI is used as a binder. Accordingly, an electrode including the binder has improved phosphoric acid retention capacity, and increased wetting velocity. Thus, a fuel cell having improved efficiency can be manufactured due to the improved proton conductivity and durability of the electrode.

The membrane electrode assembly includes: a cathode; an anode; and a polymer electrolyte membrane that is interposed between the cathode and the anode, and comprises a proton conductive polymer that is doped with acid to a doping level of less than 200 mole %. The membrane electrode assembly for the fuel cell exhibits an improved efficiency of performance when acid is doped in the polymer electrolyte membrane at a doping level of less than 200 mole. In addition, the performance of the fuel cell can be optimized by separately adjusting the amount of acid doped in the cathode and anode. The fuel cell employing the membrane electrode assembly can be operated at a high temperature in a dry environment and exhibits an improved power generating performance.
