US scientists have reported a dramatic improvement in the activity of catalytic nanoparticles destined to replace platinum in fuel cells. They say their bimetallic 'nanodendrites' are more than twice as effective than current state-of-the-art platinum catalysts and could help make future fuel cells more economically viable.
