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.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 118 words
A method of manufacturing an electrode for a fuel cell which 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 said coating roller so as to keep a space which is adjustable, arranging a paste reservoir above said doctor roller and said space between said doctor roller and said coating roller wherein said paste reservoir is provided with at least one partition part in the direction of feeding said electrode substrate, rotating said feeding roller in a specified direction while said coating roller is rotated in the same direction as said feeding roller to transfer said paste on said electrode substrate.
