Title: METHOD FOR MANUFACTURING ELECTRODE, ELECTRODE MANUFACTURED THEREBY, MEMBRANE-ELECTRODE ASSEMBLY COMPRISING SAME ELECTRODE, AND FUEL CELL INCLUDING SAME MEMBRANE-ELECTRODE ASSEMBLY
Abstract:
The present invention relates to a method for manufacturing an electrode, an electrode manufactured thereby, a membrane-electrode assembly comprising the electrode, and a fuel cell comprising the membrane-electrode assembly. The method for manufacturing an electrode comprises the steps of: preparing an electrode forming composition by mixing a catalyst with an ionomer; applying a low-frequency acoustic energy to the electrode forming composition to perform resonant vibratory mixing so as to coat the ionomer on the surface of the catalyst; and coating the electrode forming composition to manufacture an electrode. The method for manufacturing an electrode coats the ionomer on the surface of the catalyst with a nanometer thickness to increase the dispersibility of the catalyst, etc., thereby facilitating the mixing. In addition, the method for manufacturing an electrode uniformly distributes the ionomer on the surface of the catalyst to increase the utilization ratio of the catalyst and the ionomer, thereby improving various performances and increasing the coupling efficiency between the catalyst and the ionomer, such that durability is enhanced.
