This research demonstrates protonic conductivity in nanoscale fluorite- structured oxides as well as YSZ at low temperatures. The photograph shows a water concentration cell of a dense nanostructured (grain size ∼ 20 nm) Sm-doped ceria ceramic operating at room temperature. One side (cathode) of the cell is exposed to wet-air while the other side (anode) is immersed into de-ionized water. The current measured from the cell is ∼ 30 nA.
