摘要：A supported catalyst includes a carbonaceous catalyst support and first metal-second metal alloy catalyst particles adsorbed on the surface of the carbonaceouscatalyst support, wherein the difference between a D10 value and a D90 value is in therange of 0.1 to 10 nm, wherein the D10 value is a mean diameter of a randomly selected10 wt % of the first metal-second metal alloy catalyst particles and the D90 value is amean diameter of a randomly selected 90 wt % of the alloy catalyst particles. Thesupported catalyst has excellent membrane efficiency in electrodes for fuel cells due touniform alloy composition of a catalyst particle and supported catalysts that do notagglomerate.
