Carbon supported catalyst having reduced water retention

摘要

Compositions are disclosed for carbon supported catalysts with high metal loadings, high electrochemically active surface area, and good water management properties. In one aspect, the invention is directed to a carbon supported catalyst comprising a carbonaceous substrate and a dispersed metal, wherein the carbonaceous substrate has an electron microscopy surface area to nitrogen surface area ratio of at least 0.5 and a nitrogen surface area of at least 100 m²/g.
