| Zusammenfassung: | A fuel cell electrode catalyst includes catalyst metal particles and electrically conductive support particles supporting the catalyst metal particles. In the fuel cell electrode catalyst, a proportion of a surface area occupied by the catalyst metal particles with particle sizes of 4.5 nm or less to a surface area of the catalyst metal particles calculated from a transmission electron microscope image is 5% or less. |
