    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.
