A single-crystal solid oxide material, rather than a polycrystalline ceramic, is used for electrolytic and fuel-cell applications. For the electrolytic production of oxygen from carbon dioxide, a yttria-stabilized zirconia crystal is coated with platinum electrodes and encased in a platinum structure to provide a thermally stable electrolytic cell. A multilayered device is constructed by stacking crystals and spacers in alternating arrangement and by plumbing the active surfaces of the crystals in parallel through perforations drilled directly in the solid-oxide crystals, so that manifolding and sealing problems are minimized.
