Shaping triple-conducting semiconductor BaCo_0.4Fe_0.4Zr_0.1Y_0.1O_3-δ into an electrolyte for low-temperature solid oxide fuel cells.

ABSTRACT: Interest in low-temperature operation of solid oxide fuel cells is growing. Recent advances in perovskite phases have resulted in an efficient H⁺/O^2-/e^- triple-conducting electrode BaCo_0.4Fe_0.4Zr_0.1Y_0.1O_3-δ for low-temperature fuel cells. Here, we further develop BaCo_0.4Fe_0.4Zr_0.1Y_0.1O_3-δ for electrolyte applications by taking advantage of its high ionic conduction while suppressing its electronic conduction through constructing a BaCo_0.4Fe_0.4Zr_0.1Y_0.1O_3-δ-ZnO p-n heterostructure. With this approach, it has been demonstrated that BaCo_0.4Fe_0.4Zr_0.1Y_0.1O
