In it for the long haul : Clusters of Pt nanowires (3D Pt nanoassemblies, Pt NA) serve as an electrocatalyst for low‐temperature fuel cells. These Pt nanoassemblies exhibit remarkably high stability following thousands of voltage cycles (see graph) and good catalytic activity, when compared with a commercial Pt catalyst and 20 % wt Pt catalyst supported on carbon black (20 % Pt/CB).
