Overview

Crystallographic analysis reveals improved ionic conduction in bismuth oxide electrolytes with calcium doping, indicating the potential for enhanced fuel cell performance.

Key Points

  • The Bi 1.8 Gd 0.1 Er 0.05 Ca 0.05 O 3‐δ sample shows exceptional conductivity of 0.293 S·cm −1 at 800 °C, enhancing efficiency.
  • Conductivity measurements indicate that moderate calcium doping enhances the ionic conduction properties significantly.
  • The phase coexistence of δ‐Bi 2 O 3 and CaBi 6 O 10 is crucial for providing transport channels for oxygen ions.
  • These findings suggest the potential for optimizing bismuth oxide electrolytes in fuel cell applications.
