      abstract     = {High-temperature solid oxide cells are highly efficient
                      energy converters. However, their lifetime is limited by
                      rapid deactivation. Little is known about the local, atomic
                      scale transformation that drive this degradation. Here,
                      reaction-induced changes are unraveled at the atomic scale
                      of a solid oxide electrolysis cell (SOEC) operated for 550 h
                      by combining high-resolution scanning transmission electron
                      microscopy with first-principles and force-field-based
                      atomistic simulations. We focus on the structural evolution
                      of lanthanum strontium manganite (LSM)/yttria-stabilized
                      zirconia (YSZ) regions and the corresponding solid–solid
                      interface. It is found that the strong inter-diffusion of
                      cations leads to the additional formation and growth of a
                      multitude of localized structures such as a solid solution
                      of La/Mn, nano-domains of secondary structures or antisite
                      defects in the YSZ, as well as a mixed ion and electron
                      conduction region in the LSM and complexion. These local
                      structures can be likewise beneficial or detrimental to the
                      performance, by either increasing the catalytically active
                      area or by limiting the supply of reactants. The work
                      provides unprecedented atomistic insights into the influence
                      of local solid-state chemistry on the functioning of SOECs
                      and deepens the understanding of the degradation mechanism
                      in SOECs, paving the way towards nanoscopic rational
                      interface design for more efficient and durable cells.},
