Abstract

The slow rate of the oxygen reduction reaction (ORR) in the polymer electrolyte membrane fuel cell (PEMFC) is the main limitation for automotive applications. We demonstrated that the Pt 3 Ni(111) surface is 10-fold more active for the ORR than the corresponding Pt(111) surface and 90-fold more acti...
