      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.},
