    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.

    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 metal catalyst including a conductive catalyst material and a coating layer formed of a water repellent material on the conductive catalyst material, an electrode including the metal catalyst, and a fuel cell employing the electrode. By forming the coating layer, having a water repellent material, on the conductive catalyst material, the metal catalyst does not sink in the liquid electrolyte, the distribution and movement of the liquid electrolyte around the metal catalyst can be controlled, and the thickness of the interface between the metal catalyst and the liquid electrolyte can be regulated. Accordingly, an ideal electrode structure having triple phase boundary for electrochemical reaction can be formed. A fuel cell employing an electrode including the metal catalyst has excellent efficiency and overall performance.
