abstract = {The global push for clean energy has intensified research
on solid oxide fuel cells (SOFCs) and solid oxide
electrolysis cells (SOECs), collectively termed solid oxide
cells (SOCs). The fuel electrode, functioning as the anode
in SOFCs and the cathode in SOECs, is crucial for fuel
interactions. Despite the widespread use of
Ni/yttria-stabilized zirconia (Ni/YSZ) cermet due to its
affordability and mechanical strength, its long-term
performance is hindered by redox instability, Ni
agglomeration, coking, and sulfur poisoning.Perovskite-based
alternatives, particularly the double perovskite
Sr2FeMoO6-δ (SFM), have gained attention due to their
electrochemical stability, symmetrical functionality, and
mixed electronic-ionic conductivity (MIEC). A key advantage
of SFM is its in situ exsolution behavior, where B/B′-site
cations—especially when doped with transition metals like
Ni, Co, or Mn—undergo controlled exsolution upon
reduction, which eliminate the effects of agglomeration and
coking.Sr2FeMo0.65Ni0.35O6−δ (SFM-Ni) has demonstrated
superior performance due to Ni’s high catalytic activity.
However, the mechanism underlying the in situ formation of
FeNi3 nano-exsolutions remains poorly understood.
Elucidating this process is critical for optimizing material
design and enhancing SOC performance.},
