Overview

Testing shows a link between oxygen vacancies and activation energy in LSCF perovskites, indicating preparation-dependent behavior.

Key Points

  • The study found that the activation energy for oxygen reduction/evolution reactions depends on oxygen vacancy formation.
  • Activation energy values ranged from 0.5 to 24.1 kJ mol −1, showcasing significant variability based on preparation methods.
  • Electrochemical impedance spectroscopy helped assess the polarization resistance in nanofiber and granular electrode forms.
  • The intrinsic electrochemical activation energy appears consistent across different preparation procedures.
