摘要（英）：

There is provided an electrode catalyst layer that has excellent durability compared to conventional electrode catalyst layers employing carbon supports, and that can minimize as much as possible the amount of catalyst material used while exhibiting desired output, by allowing adjustment of the amount as necessary. The electrode catalyst dispersion of the disclosure comprises catalyst particles that contain a non-conductive support and a conductive catalyst material covering the surface of non-conductive support, and a dispersing medium selected from among water, organic solvents and combinations thereof. The ink composition of the disclosure comprises catalyst particles containing a non-conductive support and a conductive catalyst material covering the surface of non-conductive support, a dispersing medium selected from among water, organic solvents and combinations thereof, and an ionic conductive polymer, wherein the volume ratio of the catalyst particles and the ionic conductive polymer is 55:45-90:10. There is further provided an electrode catalyst layer.
