    摘要: 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.

    摘要: Disclosed is a fuel cell wherein deterioration of fuel cell performance due to dry up phenomenon and flooding phenomenon is suppressed. Specifically disclosed is an assembly for fuel cells or a fuel cell wherein a catalyst layer contains a first composite catalyst particle containing a catalyst supporting particle and a solid polymer electrolyte and a second composite catalyst particle having a larger volume average particle diameter than the first composite catalyst particle and arrangement of the first composite catalyst particle and the second composite catalyst particle is controlled in the thickness direction of the catalyst layer. Consequently, deterioration of fuel cell performance due to dry up phenomenon or flooding phenomenon can be suppressed, thereby realizing a fuel cell with high efficiency.
