    A new type of nanocatalyst can result in the long-awaited commercial breakthrough for fuel cell cars. Research results from Chalmers University of Technology and Technical University of Denmark show that it is possible to significantly reduce the need for platinum, a precious and rare metal, by creating a nanoalloy using a new production technique. The technology is also well suited for mass production.

    “A nano solution is needed to mass-produce resource-efficient catalysts for fuel cells. With our method, only 1/10 as much platinum is needed for the most demanding reactions...
