      abstract     = {Protonic ceramic fuel cells offer a high potential to
                      produce electrical energy in a very efficient way. The
                      performance of such devices is highly dependent on the
                      electrolyte material and its thickness. In this work
                      half-cell assemblies, consisting of
                      Ba1.015Zr0.625Ce0.2Y0.175O3-δ electrolyte layer (final
                      thickness ≤ 15 µm) supported on much thicker porous
                      cermet Ba1.015Zr0.625Ce0.2Y0.175O3-δ:Ni anode (final
                      thickness 350-700 µm), were developed via the inverse tape
                      casting processing technique. Powders were prepared by the
                      solid state reactive sintering and NiO was added to the
                      electrolyte powder sintering aid facilitating sintering. The
                      chemical composition and the physical characteristics of the
                      starting powders were thoroughly analyzed and by need,
                      adjusted to the tape casting fabrication process. The
                      shrinkage rates of electrolyte and anode substrate single
                      layers, as well as of the assemblies thereof were explored
                      by optical dilatometry in order to optimise the de-binding
                      and sintering procedures. Sintering experiments carried out
                      at different heating regimes showed that to achieve the
                      desired half-cell microstructure, including electrolyte gas
                      tightness and flat reproducible geometry of the assemblies,
                      sintering temperature of 1450°C was optimally required. The
                      influence of the processing and sintering parameters on the
                      final cell microstructure was investigated in details by XRD
                      and SEM-EDX studies. The formation of BaY2NiO5 transient
                      liquid phase during the sintering was confirmed. The
                      tape-cast cells were electrochemically characterized after
                      anode support reduction and the proton conductivity of the
                      electrolyte was 0.003 S/cm at 600°C, which is comparable to
                      the literature data. Finally, half-cell assemblies were
                      successfully scaled-up to 25 cm2 area. Finally, this work
                      demonstrates two key results: (i) the combination of tape
                      casting and reactive sintering is able to produce large-area
                      electrolyte-anode assemblies for a comparably low Ce content
                      of 20 $mol.\%$ and ii) the achieved total proton
                      conductivity is suitable for PCFC application.},
