Platinum-rich shell, platinum-poor core

Hydrogen fuel cells will power the automobiles of the future; however, they have so far suffered from being insufficiently competitive. At the University of Houston, Texas, USA, a team led by Peter Strasser has now developed a new class of electrocatalyst that could help to improve the capacity of fuel cells. The active phase of the catalyst consists of nanoparticles with a platinum-rich shell and a core made of an alloy of copper, cobalt, and platinum. This catalyst demonstrates the highest activity yet observed for the reduction of oxygen.
