000908327 520__ $$aAcceptor doped barium zirconate-cerate ceramic electrolytes constitute prospective materials for highly-efficient electrochemical devices. This class of materials is particularly suitable because of  their much higher mobility of protons within the intermediate temperature range. On the lab scale, devices with these materials have made significant progress in recent years. Ranging from newly developed, high-conducting electrolytes and precisely adjusted air electrode designs, providing a path for further performance improvement at moderate temperatures, thus transforming the way we convert and store energy. Despite this progress, hurdles remain in scaling-up robust and affordable planar-type devices for commercialization. This paper addresses these hurdles by employing a cost-effective inverse tape casting route and screen printing to fabricate flat planar protonic electrochemical devices. The processing parameters were analyzed and adjusted to obtain defect-free half-cells of 5 cm x 5 cm dimensions with diminished warping. Furthermore, including a NiO-SrZr0.5Ce0.4Y0.1O3-d substrate layer yields a easily sintered electrolyte layer after  co-sintering at 1350 oC/5h. Typical single-cell operated in electrolysis mode reached reproducible terminal voltages of 1.2 V @ 500 mA/cm^2  at 600 oC. Based on the above results, the calculated amount of electricity to produce 1 Nm^3 of H2 is about 3.5kWh1, which is  at least 30% reduced from the conventional low-temperature water electrolysis. Finally, in the fuel cell mode, the impedance spectra were deconvoluted to identify all performance-related polarization processes via the distribution of relaxation time.
