      abstract     = {Doped ceria pellets with the composition
                      Ce0.8Gd0.2-xPrxO2-δ with x = 0.15, 0.1, 0.05, and 0.03 were
                      investigated with a special focus on the partial
                      conductivities in the temperature range of 200–600°C.
                      Temperature dependent conductivity provided by impedance
                      spectroscopy in air was compared to measurements of the
                      oxygen partial pressure dependent electronic conductivity.
                      The electronic conductivity was analyzed down to 200°C by
                      using a modified Hebb-Wagner setup with encapsulated Pt
                      microcontacts. A small polaron hopping process introduced by
                      reduction of praseodymium was found to have a pronounced
                      influence on the electronic conductivity at low
                      temperatures. A splitting of the maximum introduced by
                      praseodymium small polaron hopping was observed. Especially
                      for the compositions x ≤ 0.1, a strong deviation of the
                      electronic conductivity curves from the standard acceptor
                      doping case was measured due to superimposed electronic
                      conductivity from the Pr3+/4+ redox reaction.},
