Researchers at University College London, Queen Mary University of London and Humboldt Universität zu Berlin have suggested a design for a hydrogen fuel cell, with graphene as a key component. The new research promises to address some of the roadblocks that have thus far hindered the development of this clean, non-toxic, renewable technology, thus opening up hydrogen fuel cells as a potential clean-energy breakthrough.
At the moment the US Department of Energy estimates that the cost of energy generated by hydrogen fuel cells is around $61 per kilowatt. The ultimate aim is to get this down to $30 per kilowatt. The scaling up in the production of graphene-coated nanoparticles suggested in the paper could help significantly in this quest. The team’s findings could also extend beyond the field of fuel cells, lending itself to some exciting technological applications.
