Platinum Nanoparticle (IMAGE) Technical University of Munich (TUM) Caption An interdisciplinary research team at the Technical University of Munich (TUM) has succeeded in optimizing the size of platinum nanoparticles for fuel cell catalysis so that the new catalysts are twice as good as the currently best commercially available processes. Platinum nanoparticles with 40 atoms exhibit the highest activity.
