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.

摘要： An electrode catalyst layer for a fuel cell includes a first region and a second region more highly water repellent than the first region. The amount of catalyst per unit area in the first region is smaller than the amount of catalyst per unit area in the second region. The electrode catalyst layer makes it possible to reduce the amount of catalyst contained in the electrode catalyst layers, while avoiding a drop in output voltage of the fuel cell.

摘要： The battery performance of a solid polymer fuel cell is enhanced by improving a three-phase interface. A catalyst carrier conductive material 10, solid polymer electrolyte 20 and 30, and a good solvent and a poor solvent with respect to the solid polymer electrolyte are mixed so as to prepare an ink in which at least part of the solid polymer electrolyte is colloidalized. The ink is then dried to produce a powder catalytic material 40, which is applied to an electrolyte membrane or a gas diffusion layer, thereby forming a catalyst layer of an electrode.
