Abstract
A unitized electrode assembly for a fuel cell includes an anode electrode, a cathode electrode, an electrolyte and palladium catalytic nanoparticles. The electrolyte is positioned between the cathode electrode and the anode electrode. The palladium catalytic nanoparticles are positioned between the electrolyte and one of the anode electrode and the cathode electrode. The palladium catalytic nanoparticles have a {100} enriched structure. A majority of the surface area of the palladium catalytic nanoparticles is exposed to the UEA environment.
