Abstract
to enhance its electrochemical performance. A Schottky junction barrier is formed at the anode to avoid short circuit problems and facilitate the ionic transportation at the anode/electrolyte interface. This study indicates that wide-band gap semiconductors with suitable element-doping can be tuned to be promising ionic conductors for advanced fuel cell applications.
