      abstract     = {The chemical compatibility of thin electrolyte layers and
                      their support materials at high temperatures is crucial for
                      the performance in solid oxide cells and membranes. This
                      work describes the chemical interaction between the
                      electrolyte material, BaCe0.2Zr0.7Y0.1O3 + 0.5 $wt\%$ NiO
                      (BCZY), and structural ceramics Al2O3, 8 $mol\%$
                      yttriastabilized zirconia (8YSZ), TiO2, CeO2 and MgO during
                      sintering. 1:1 $wt\%$ powder mixtures of the electrolyte
                      material and structural ceramics were annealed at 1500 ◦C
                      for 5 h, with the phase composition being determined through
                      XRD analysis at room temperature. Subsequently, the material
                      interaction between BCZY films depositedon the most
                      promising structural ceramic MgO was investigated by SEM and
                      EDS. In particular, the complex sintering requirements to
                      form single-phase BCZY electrolyte layers is troubled upon
                      coating and sintering BCZY on MgO. Hereby, the diffusion of
                      NiO into the MgO support leads to a deficiency of NiO in the
                      BCZY layer,making the solution and precipitation mechanism
                      required to form the perovskitic phase unable to occur. In
                      extreme scenarios, the electrolyte layer depletion of NiO
                      can even cause the decomposition of a single-phase BCZY into
                      BaZrO3, Ce-Y fluorite and a BCZY perovskite phase of
                      undefined composition.},
