    摘要: A method of preparing a metal catalyst including a conductive catalyst material and a coating layer formed of a water repellent material on the surface of the conductive catalyst material includes: obtaining a water repellent material solution by mixing a water repellent material and a first solvent; obtaining a conductive catalyst solution by mixing a conductive catalyst material and a first solvent; mixing the water repellent material solution and the conductive catalyst solution; casting the result onto a supporter, drying the cast result and then separating a metal catalyst in a solid state from the supporter; and pulverizing and sieving the product. Also provided are a metal catalyst prepared using the method, an electrode including the metal catalyst, a method of preparing the electrode, and a fuel cell employing the electrode. A metal catalyst including a coating layer formed of a water repellent material on the surface of a conductive catalyst particle can be obtained by using the method of preparing a metal catalyst. Such a metal catalyst does not sink into a liquid electrolyte since hydrophobicity is efficiently distributed around the conductive catalyst particle. Also, the distribution and movement of the liquid electrolyte, such as phosphoric acid, around the metal catalyst can be controlled. A fuel cell employing the metal catalyst has excellent efficiency and overall performance.

    摘要: The present invention provides a separator for a fuel cell that comprises a metal substrate that contains at least one metal element M and a surface layer formed on a surface of the metal substrate and that contains at least one conductive oxide represented by LaMxO3 (wherein x=0 to 1). Also, the present invention provides a method for anti-corrosion treatment of a metallic separator for a fuel cell. The method involves first forming an La layer on a surface of a metal substrate having a desired dimension and a desired flow field formed therein. Next, the metal substrate having the La layer on its surface is heated such that at least one metal component contained in the metal substrate is diffused into the La layer and an La component in the La layer is diffused into the metal substrate to form a mixed layer composed of La and the at least one metal component on the surface of the metal substrate. Finally, the mixed layer is heated under an oxidizing atmosphere to form a layer composed of oxides containing La and the at least one metal component on the surface of the metal substrate.

    摘要: A metallic separator for a fuel cell including 2.2 to 6.0 parts by weight of tungsten based on 100 parts by weight of stainless steel containing molybdenum, and the weight ratio of molybdenum to tungsten (Mo/W) is 0.15 to 1.60. The separator for fuel cells has excellent anti-corrosive properties and contact resistance as low as that of a metal material, and thus, a fuel cell having high efficiency can be manufactured at a reasonable cost using the separator.
