      abstract     = {Proton-conducting solid oxide electrolytes are highly
                      appealing for producing hydrogen on a large scale through
                      steam electrolysis at moderate temperatures. Yet, processing
                      such electrolytes for industrial purposes poses several
                      challenges. This paper presents an economical tape-casting
                      route that produces flat, planar protonic electrolysis cells
                      with impressive dimensions of up to 100mm x 100mm x 0.5mm.
                      These cells are constructed using NiO-SrZr0.5Ce0.4Y0.1O3-d
                      as the substrate, which ensures minimal warping and no
                      cracks in the end-fired state.􀀃The three-layered green
                      tapes achieved dense, gas-tight electrolyte layers after
                      co-sintering at 1300 ºC for 5 hours. Using Ba0.5La0.5CoO3-d
                      as the anode electrode demonstrates remarkable capabilities
                      and endurance within the 500-600 °C temperature range, as
                      indicated by its current-voltage characteristics and
                      hydrogen evolution rates. Furthermore, based on Raman
                      spectra analysis and mappings of the half-cell surface and
                      cross-section (as illustrated in Figure 1), it is apparent
                      that sintering at temperatures above 1350 °C leads to the
                      emergence of fresh crystal defects that alter the perovskite
                      host lattice. These issues together with polarization
                      processes that impact performance in the fuel cell mode
                      identified through impedance spectra analysis of will be
                      presented. Acknowledgment: The authors gratefully
