Stable, easily sintered BaCe0.5Zr0.3Y0.16Zn0.04O3−δ electrolyte-based protonic ceramic membrane fuel cells with Ba0.5Sr0.5Zn0.2Fe0.8O3−δ perovskite cathode

Stable, easily sintered BaCe0.5Zr0.3Y0.16Zn0.04O3−δ electrolyte-based proton-conducting solid oxide fuel cells by gel-casting and suspension spray

“…As can be seen, the BZCYZn electrolyte is about 20 m in thickness, quite dense and adhered very well to the layers of anode and cathode. The cells have higher power density than the values (236 and 122 mW cm −2 at 700 and 600 • C) in previous studies [14]. The result may mainly come from the lower resistances of electrolyte and cathode.…”

“…This is indeed encouraging. Recently we have successfully prepared cells with Zn, Y, and Zr doped BaCeO 3 electrolyte [14]. The electrolytes in the above cells, however, were rather thick and were made by co-pressing two kinds of ceramic powders, which is not suitable to fabricate cells with larger area for practical purpose.…”

A new cobalt-free composite cathode Pr 0.6 Sr 0.4 Cu 0.2 Fe 0.8 O 3−δ -Ce 0.8 Sm 0.2 O 2−δ for proton-conducting solid oxide fuel cells

“…Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. conductivity and better chemical stability than BaZr 0.1 Ce 0.7 Y 0.2 O 3-δ and has been employed as the electrolyte material for H-SOFCs showing a desirable electrochemical performance in a long-term operation [7][8][9]. Considering the above reasons, BaZr 0.3 Ce 0.5 Y 0.2 O 3-δ was adopted as electrolyte in this work.…”

Mathematical Modeling Analysis and Optimization of Key Design Parameters of Proton-Conductive Solid Oxide Fuel Cells

“…Due to these reasons novel perovskite oxide materials are chosen as cathode. Recently, Ba 0.5 Sr 0.5 Zn 0.2 Fe 0.8 O 3−δ (BSZF) has been developed as a novel cobalt free oxygen permeable membrane with high permeation behavior and good chemical stability at high temperatures [17].…”
