Abstract
Abstract A method of manufacturing an electrode for a fuel cell comprises placing a coating roller opposing a feeding roller with a space through which an electrode substrate is passed, placing a doctor roller with respect to the coating roller so as to keep a space which is adjustable, arranging a paste reservoir above the doctor roller and the coating roller so that paste flows to the space between the doctor roller and the coating roller, rotating the feeding roller in a specified direction while the coating roller is rotated in the same direction as the feeding roller to transfer the paste on the electrode substrate.
