Patent ID: 7091149

Claim:
A method of manufacturing an electrode for use in a fuel cell, comprising the steps of: (a) coating a first paste containing a carbon material and polytetrafluoroethylene on a base which will serve as a gas diffusion layer; (b) pressurizing while heating the coated first paste to volatilize a solvent as a vapor from said first paste, and drying the coated first paste into a water-repellent layer; (c) coating a second paste containing a carbon material carrying a catalyst on said water-repellent layer; (d) pressurizing while heating the coated second paste to volatilize a solvent as a vapor from said second paste, and drying the coated second paste into an electrode catalyst layer; (e) carrying out said step (d) while said base is being interposed between a porous sheet and a polymer sheet covering said second paste, said porous sheet being a separate sheet from said base, wherein said solvent volatilized as said vapor from said second paste is absorbed in said porous sheer; and (f) peeling off said polymer sheet and said porous sheet absorbing said vapor therein from said base after said electrode catalyst layer is formed by driving.
