Abstract
A method for producing an electrode catalyst substrate is provided herein, which comprises a carbon film forming step of forming a porous carbon film on a base, a hydrophilization step of hydrophilizing the porous carbon film, an immersion step of immersing the base in a solution prepared by dissolving catalytic metal ions in a polar solvent, and a reduction step of adding a reducing agent to the solution and thus reducing the catalytic metal ions. An electrode catalyst substrate obtained by the method and a polymer electrolyte fuel cell in which the electrode catalyst obtained by the method is used for anodes and/or cathodes are also provided herein. In the electrode catalyst of the present invention, fine catalyst particles are loaded in a uniform and highly dispersed manner.
