Graphene and atomically thin crystals of boron nitride conduct protons far better than predicted and could radically enhance the performance of hydrogen fuel cells, according to an international research team (Nature 2014, DOI: 10.1038/nature14015).

Over the past decade, scientists have found that forcing ions or atoms through even a single layer of graphene is virtually impossible without the help of a particle accelerator. Theorists had predicted that, at room . . .
