Hydration of Oxygenated Species on Platinum Fuel Cell Cathode

In-situ soft x-ray photoelectron spectroscopy and electronic structure simulations identified the adsorbed oxygenated species on platinum fuel cell cathodes during the oxygen reduction reaction. Two distinct pathways of oxygen reduction mediate the formation of reactive non-hydrated OH and less-reactive hydrated OH on platinum cathodes. Tuning the hydration will be crucial for developing more active fuel-cell cathodes, which can reduce platinum usage.
