Influence of anode pore forming additives on the densification of supported BaCe0.7Ta0.1Y0.2O3−δ electrolyte membranes based on a solid state reaction

Chemically Stable Pr and Y Co‐Doped Barium Zirconate Electrolytes with High Proton Conductivity for Intermediate‐Temperature Solid Oxide Fuel Cells

“…Figure shows the current density‐voltage ( I– V ) and power‐density curves for the developed BZPY02‐based single cell measured at different temperatures. The OCV values of 0.99, 0.96, 0.93, and 0.9 V at 500, 550, 600, and 650 °C, respectively, were close to other anode‐supported SOFCs based on proton‐conducting electrolytes,42–44 indicating that the BZPY02 electrolyte membrane was dense enough to prevent major gas leakages. Using humidified hydrogen (ca.…”

Advanced materials for SOFC application: Strategies for the development of highly conductive and stable solid oxide proton electrolytes

“…61 Alongside with the overview of stability of BaCeO 3 -based materials against H 2 O, and acidic components, other aspects of materials stability are briefly considered. The ideal potential proton-conducting electrolyte systems should have monotonic change of thermal expansion, good chemical compatibility with electrode systems and no Ba-loss under synthesis and sintering procedures.…”

A Performance Study of Solid Oxide Fuel Cells With BaZr0.1Ce0.7Y0.2O3–δ Electrolyte Developed by Spray‐Modified Pressing Method

“…It should be acknowledged that suspension spray method has been used to develop either electrode or electrolyte before [31][32][33]37]. Nonetheless, spray-modified pressing here is different from that method technologically, and has not been published heretofore to produce proton-conducting electrolyte except a Gd-doped CeO 2 electrolyte [38].…”

“…Directly reducing the electrolyte thickness offers a comparatively simple and effective way to achieve high cell performance. While methods such as dry-pressing [22], tape casting [23], screen printing [24], slurry spin-coating [25][26][27][28], etc., are readily available to fabricate electrolytes like Samaria-doped ceria (SDC), yttria-stabilized zirconia (YSZ), the approach used most frequently to prepare BaZr 0.1 Ce 0.7 Y 0.2 O 3-d (BZCY) electrolyte based fuel cells has been limited to dry-pressing [29,30] or spray-coating [31][32][33] to date. Dry pressing method is a cost-effective method.…”
