摘要
Bismuth Oxides In article number 2306205, Eric D. Wachsman, Kang Taek Lee, and co-workers report outstandingly conductive and stable bismuth oxides through a rational triple-doping strategy. The developed bismuth oxides show ≈140 times higher conductivity than YSZ for 1000 h at 600 °C. Designed low-temperature solid oxide electrochemical cells, utilizing the bismuth oxides, exhibit exceptional performances in both fuel cell (2.02 W cm−2) and electrolysis modes (0.95 A cm−2 at 1.3 V) at 600 °C.
