Caption

Structure enables a carbon-based catalyst to perform comparably with metal catalysts in an acidic fuel cell. A: Carbon black agglomerates maintain a clear distance between graphene sheets imbedded with carbon nanotubes, allowing oxygen and electrolyte to flow through and speeding the oxygen-reduction reaction. B: Without the agglomerates, the sheets stack closely, stalling the reaction.
