Abstract:
1. A method of manufacturing a membrane-electrode assembly for a full cell comprising: providing a polymer electrolyte membrane; and forming a first electrode on one side of the polymer electrolyte membrane and a second electrode on the other side of the polymer electrolyte membrane, said at least one of the first electrode and the second electrode being formed by: growing a first catalyst on one side of the polymer electrolyte membrane toward an electrode substrate to form a first catalyst layer; and providing a second catalyst layer including a second catalyst and an electrode substrate to form the second catalyst layer interposed between the first catalyst layer and the electrode substrate, wherein the first catalyst comprises a first metal catalyst directly grown on the polymer electrolyte membrane toward the electrode substrate with a shape selected from the group consisting of a nanohorn, a nanorod, a nanofiber, and combinations thereof.
