'Defective' graphene makes for super-efficient fuel cells
Like a runway model, graphene is nice to look at, but can't do a whole lot. When you add a few warts and imperfections, however, it becomes more interesting -- specifically, it has the potential to make fuel cells better and cheaper.
Scientists fromNorthwestern University and other institutions were toying with the material as a hydrogen fuel cell membrane, and found that by knocking out at least four carbon atoms from the normally pristine structure, it performed vastly better. A large number of protons (and nothing else) slipped through imperfections in the atom-thick material in just a few seconds, efficiently generating electricity.
