Y-doped BaZrO₃as a chemically stable electrolyte for proton-conducting solid oxide electrolysis cells (SOECs)

Abstract

A proton-conducting SOEC with chemically stable Y-doped BaZrO3is fabricated for the first time for electrolysis applications.

Metal‐Supported Solid Oxide Electrolysis Cell with Significantly Enhanced Catalysis

“…Figure 8c compares the electrolysis performance of our optimized cells with those of oxygen-conducting SOECs reported in the literature. [15,18,22,28,31,[37][38][39]73,99] Some recent advances of electrolysis cells based on proton conductors (such as [29,[101][102][103] ) are not shown here, as the operating temperatures (400-600 C) and steam contents (up to 10 vol%) reported for these proton-conducting SOECs are very different from the ones based on conventional oxygen conductors (700-900 C, 50 vol% or higher steam content). The cell with Pr 6 O 11 -SDC oxygen electrode achieved very high electrolysis performance, surpassing conventional electrode-supported cells and all previous metal-supported electrolysis cells.…”

Detrimental Effect of Sintering Additives on Conducting Ceramics: Yttrium‐Doped Barium Zirconate

“…Not only fuel cells, but other electrochemical devices,i ncluding electrolyzers, [53,54] hydrogen separation [55,56] and methane reforming materials, [57,58] have been fabricated by such a method.H owever,a sc larified in our preliminary experiment (Figure 1), regardless of whether sintering additives were added on purpose or not, NiO in the anode diffused into the electrolyte layer and played the role of the sintering additive.

An efficient gel-combustion synthesis of visible light emitting barium zirconate perovskite nanoceramics: Probing the photoluminescence of Sm 3+ and Eu 3+ doped BaZrO 3

“…Barium Zirconate (BZO) in particular has been explored for various technological applications because of its interesting physico-chemical properties like wide band gap, high refractive index, high melting temperature, small coefficient of thermal expansion, doesn't undergo any phase change upto 1600 K and high dielectric permittivity [6][7][8]. These properties make BZO an interesting material that can be used for various applications like proton-conducting solid oxide electrolysis [9], photocatalyst [10,11], electromechanical material [12], luminescence host [13] etc. It is also used as corrosion protective agent in growth process of superconductor [14].…”
