      abstract     = {A novel method for the preparation of a thin oxidic
                      proton-conducting electrolyte is presented. This kind of
                      supported film was studied in detail as it is applicable for
                      IT–SOFC, H2 membranes, and advanced catalytic converters.
                      Thin-film (∼5 μm) proton-conducting membranes with the
                      nominal composition BaZr0.85Y0.15O3−δ (BZY) were prepared
                      over porous Ni–8YSZ/Ni–BZY substrates by the solid-state
                      reaction of a gastight 8YSZ layer and a coated BaCO3 layer.
                      The resulting asymmetric membranes are of a homogeneous
                      composition and are gastight. Indeed, XRD analysis showed a
                      highly crystalline cubic perovskite. The solid-state
                      reaction promoted the formation of (i) an electrolyte with
                      very fine (∼100 nm) grains and high packing density and
                      (ii) an unexpected porous needle-like top layer with a
                      nominal composition similar to that of the protonic
                      electrolyte, to which it is intimately attached. The layer
                      morphology, phase distribution, and lattice composition were
                      investigated by EDS–SEM, EDX as well as SIMS. Conduction
                      properties of the protonic material were investigated by DC
                      conductivity of pressed bars under different gas
                      compositions and also by impedance spectroscopy of a
                      supported thin film.},
