摘要： The technology useful for the realization of a fuel cell that excels in not only the initial performance but also the post-endurance performance is provided. A supported catalyst for fuel cell includes a conductive carrier and platinum supported on the conductive carrier. A 90% particle diameter D 90 on a cumulative particle size curve obtained by determining a particle size distribution of the supported catalyst by a light scattering method is 28 µm or less.
