      abstract     = {Ceramic proton conductors have the potential to become
                      important components in future clean and efficient energy
                      technologies. In this manuscript, barium cerium yttrium
                      zirconate (Ba(Zr0.5Ce0.4)8/9Y0.2O2.9) and strontium cerium
                      yttrium zirconate (SrZr0.5Ce0.4Y0.1O2.95), proton conducting
                      perovskites were employed as solid oxide electrolysis cell
                      (SOEC) electrolytes for hydrogen production via intermediate
                      temperature steam electrolysis at 550 and 600 °C.
                      Cathode-supported button cells examined for a 12 μm
                      Ba(Zr0.5Ce0.4)8/9Y0.2O2.9 electrolyte, with
                      Ni–SrZr0.5Ce0.4Y0.1O2.95 as the H2-electrode, and porous
                      Ba0.5La0.5CoO3 as the anode reached current densities of 0.2
                      and 0.5 A cm−2 with applied voltage of 1.45 V, at 550 and
                      600 °C, respectively. Moreover, a hydrogen evolution rate
                      of 127 μmol cm−2 per minute was achieved at 0.5 A cm−2,
                      translating to a current efficiency of $82\%.$ In addition,
                      excellent cell performance was obtained using
                      SrZr0.5Ce0.4Y0.1O2.95 as an electrolyte. Current densities
                      of 0.2 and 0.5 A cm−2 were obtained at 600 °C with
                      applied voltages of 1.28 and 1.63 V, achieving faradaic
                      current efficiencies of 88 and $85\%.$ The
                      NiO–SrZr0.5Ce0.4Y0.1O3−δ composite cathode was more
                      favorable for the densification of the supported
                      Ba(Zr0.5Ce0.4)8/9Y0.2O2.9 electrolyte during sintering and
                      could be promising for use as a cathode substrate in
                      proton-conducting SOECs.},
