ABSTRACT:
Disclosed herein is a membrane electrode assembly with a superior power generating efficiency and a method of manufacturing the same. Also disclosed is a manufacturing apparatus thereof wherein a gasket with an optimum thickness can be easily applied to the membrane electrode assembly without preparing various types of gaskets. A method of manufacturing the membrane electrode assembly with catalytic layers and gas diffusion layers on surfaces of the electrolyte membrane comprises controlling a molding thickness according to thicknesses of the catalytic layers and the gas diffusion layers and integrally molding the gasket portions formed with resin materials on at least one surface of the electrolyte membrane.
