<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing an electrode for a fuel cell, capable of simplifying the number of processes while excellently keeping a dispersion condition of polytetrafluoroethylene (PTFE) particles in electrode slurry. <P>SOLUTION: An adjusting process to adjust the electrode slurry by dispersing a solid content containing at least either one of a catalyst component or a carbon particle and a polytetrafluoroethylene component in water serving as a dispersion medium, so that the ratio of the solid content to water (weight ratio) is kept in a range of 1 ≤ water/solid content ≤ 10, a viscosity adjusting process to add a polycarboxylic acid based surface active agent to the electrode slurry adjusted in the adjusting process, an applying process to apply the electrode slurry to which the polycarboxylic acid based surface active agent is added to a base material, and a thermally molding process to thermally pressurize the solid content after removing the dispersion medium are provided. The viscosity of the electrode slurry can be controlled to any optional range by changing the amount of the polycarboxylic acid based surface active agent to be added. <P>COPYRIGHT: (C)2004,JPO |
