University of Dayton researchers have shown that arrays of vertically grown carbon nanotubes could be used as the catalyst in fuel cells.

The carbon nanotubes, which are doped with nitrogen, would be much cheaper and longer lasting than the expensive platinum catalysts used now, with four times higher current densities.

University of North Carolina at Chapel Hill researchers who developed a new, simple-to-produce material that boosts the performance of fuel cells many times — and could be a major step toward making them affordable.
