Graphene holds a lot of promises. The lightweight, atom-thin sheet of carbon with a honeycomb structure is stronger than steel, and far more conductive than copper. Scientists are still struggling to create perfect sheets of graphene for such applications. But a new study reveals that even ‘defective’ graphene could be extremely useful in certain situations.

A team of scientists led by Franz Geiger of Northwestern University discovered that graphene could serve as a proton-selective permeable membrane, improving hydrogen fuel cells. Findings of the study were published in the latest issue of the journal Nature Communications. The study shows unprecedent...
