Abstract
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.
