Planar proton-conducting ceramic cells for hydrogen extraction
Abstract
Proton-conducting ceramics, which selectively separate H<sub>2</sub> from any hydrogen-containing gas could play a role in the future of the growing hydrogen market. In recent years, membrane technologies related to H<sub>2</sub> extraction became attractive solutions to produce pressurized high-purity hydrogen. Yttrium-doped barium zirconate/cerate materials (BaCe<sub>x</sub>Zr<sub>1-x-y</sub>Y<sub>y</sub>O<sub>3-δ</sub>) are among the most studied and used materials. In this study, symmetrical cells consisting of a protonic electrolyte (BaCe<sub>0.2</sub>Zr<sub>0.7</sub>Y<sub>0.1</sub>O<sub>3-δ</sub> (BCZY27), 10‒15 μm in thickness) surrounded by two cermet electrodes (BCZY27–Ni (50‒50 vol.%), 150 μm) were prepared for H<sup>2</sup> extraction applications. The cells were prepared via tape-casting and co-sintered at 1575 °C. The cells were up-scaled to an area of 135 cm<sup>2</sup>. The fracture toughness of the cermet electrodes was determined to be 2.07 (±0.05) MPa∙m<sup>1/2</sup> at room temperature using the double torsion technique. Impedance spectra were recorded on the symmetrical cells between 650 and 800 °C in 3% humidified 50% H<sub>2</sub>/50% N<sub>2</sub> atmosphere and at 650 °C varying the hydrogen partial pressure (20% < pH2<100%). In 50% H<sub>2</sub>/50% N<sub>2</sub> with 3% H<sub>2</sub>O the cells demonstrated an ohmic resistance of 0.59 and 0.44 Ω cm,<sup>2</sup> an average electrode polarization resistance of 0.10 and 0.09 Ω cm<sup>2</sup> (per one electrode) at 650 and 800 °C, respectively. Moreover, a stability test was performed over 400 h highlighting the stable electrochemical properties of the symmetrical membranes.
