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.},
