The most obvious obstacles for the widespread adoption of fuel cell technology are cost and performance. Although they promise benefits over internal combustion engines and batteries in terms of environmental impact, they are still fairly limited in use for these reasons. One of the most expensive elements used in most fuel cells is platinum, but now researchers have created a unique core and shell nanoparticle that uses far less platinum, yet performs more efficiently and lasts longer than commercially available pure-platinum catalysts at the cathode end of fuel cell reactions.
