Highly active catalysts for the oxygen reduction reaction are valuable for fuel cells. Here the authors evaluate catalytic activity of single-crystal platinum electrodes in acidic solutions that contain hydrophobic cations, which prevent the adsorption of poisoning species and form an efficient interface.
