      abstract     = {Integration of doped ceria into fuel electrode-supported
                      solid oxide cells is challenging due to high sintering
                      temperatures leading to undesirable interdiffusion between
                      the layers.We investigate the influence of the dopant in
                      ceria X0.1Ce0.9O1.95 (10XDC, X = Y, Gd or Sm) on the
                      interdiffusion with yttria-stabilized zirconia (8YSZ).
                      Powder mixtures of 8YSZ and 10XDC were sintered at
                      temperatures between 1000 and 1400 °C to quantify the phase
                      formation. Interdiffusion in layered systems sintered at
                      1400 °C was investigated by SEM. Symmetrical Ni-10XDC cells
                      with an 8YSZ electrolyte were analyzed using impedance
                      spectroscopy. Despite small differences in the
                      interdiffusion behavior, different dopants do not lead to
                      significant changes in the cell impedance.Notably, the
                      presence of NiO in the fuel electrode leads to enhanced
                      interdiffusion kinetics of 10XDC with 8YSZ and the formation
                      of porosity at the electrolyte interface. The detrimental
                      influence of these microstructural changes on the electrode
                      performance was investigated.},
