abstract = {Interdiffusion phenomena and secondary phase formation at
the interface La0.58Sr0.4Co0.2Fe0.8O3-δ (LSCF) /
Gd0.2Ce0.8O2-δ (GDC) / Y0.16Zr0.84O2-δ (YSZ) are
correlated to linear and non-linear losses in symmetrical
and full SOFC cells. FIB/SEM (focussed ion beam / scanning
electron microscopy) tomography is applied for determining
the local distribution of the primary phases LSCF, GDC, and
YSZ and elemental analysis via STEM/EDXS (scanning
transmission electron microscopy / energy dispersive X-ray
spectroscopy) provides information on the secondary phase
SrZrO3 (SZO) and the interdiffusion between GDC and YSZ
(ID). This reveals the effect of GDC co-sintering
temperature (varied from 1100°C to 1400°C), alongside the
sintering of LSCF at 1080°C, on these multi-layered
microstructures. Electrochemical impedance spectra on
symmetrical cells show that the polarization resistance
(ASRcat) of the cathode/electrolyte interface is
pronouncedly affected by three orders of magnitude, changing
the overall power density of anode supported SOFC single
cells at 0.8V by as much as a factor of 20. In conclusion,
the chemical composition of the ID has a tremendous impact
on the electrochemical efficiency of the investigated
LSCF/GDC/YSZ interface, and processing parameters of anode
supported cells with LSCF cathode have to be carefully
chosen for individual SOFC cell concepts.},
