    • 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.

    • A crosslinked object of a polybenzoxazine-based compound formed of a polymerized resultant of a first monofunctional benzoxazine-based monomer or a second multifunctional benzoxazine-based monomer with a crosslinkable compound, an electrolyte membrane including the crosslinked object, a method of preparing the electrolyte membrane, and a fuel cell employing the electrolyte membrane including the crosslinked object. The crosslinked object has a strong acid trapping capability with respect to the benzoxazine-based compound and high mechanical properties due to the crosslinking. The crosslinked object is very stable chemically because of elimination of solubility in polyphosphoric acid. The electrolyte membrane including the crosslinked object has excellent phosphoric acid supplementing capacity at a high temperature and mechanical and chemical stability. Specifically, even when an impregnated amount of a proton carrier, such as phosphoric acid, is increased to increase proton conductivity, the electrolyte membrane maintains excellent mechanical and chemical stability. Accordingly, the electrolyte membrane can be used in a fuel cell for high temperature and no humidity.
    • 由第一单官能苯并恶嗪类单体或第二多官能苯并恶嗪类单体与可交联化合物的聚合产物形成的聚苯并恶嗪系化合物的交联物,包含交联物的电解质膜,制备电解质膜的方法 以及使用包含交联物的电解质膜的燃料电池。 交联物质相对于苯并恶嗪类化合物具有强的酸捕获能力,并且由于交联而具有高机械性能。 由于消除了在多磷酸中的溶解度,交联物质在化学上非常稳定。 包括交联物质的电解质膜在高温下具有优异的磷酸补充能力和机械和化学稳定性。 具体地说,即使提高磷酸等质子载体的浸渍量而使质子传导性提高,电解质膜也保持良好的机械和化学稳定性。 因此,电解质膜可以用于高温,无湿度的燃料电池。

    • An electrolyte membrane includes a cross-linked reaction product of a benzoxazine monomer and a cross-linkable compound. The electrolyte membrane is impregnated with 300 to 600 parts by weight of phosphoric acid based on 100 parts by weight of the electrolyte membrane, and has a yield strain 0.5% or less, and a yield stress 0.3 Mpa or less. The cross-linked material has a strong acid trapping ability with respect to the benzoxazine compound and excellent mechanical properties due to a cross-linkage. Also, the solubility of the cross-linked material in polyphosphoric acid is low, thereby showing excellent chemical stability. Accordingly, when the cross-linked material is used, an electrolyte membrane having an excellent liquid supplementing ability and excellent mechanical and chemical stability at a high temperature can be obtained. The cross-linked material can be obtained by a simple polymerization process by combining a benzoxazine monomer and a crosslinkable compound and by using heat instead of using a polymerization initiator or a cross-linking agent.
