Abstract [en]

The hybrid ionic conduction of ceria-carbonate composite is an interesting field that has attracted plenty attention in the past decade. However, it has not reached universal agreement among the researcher. Novel characterization method is still needed to reveal this complex system and benefit the future advanced materials design and development. In this work, the electrolysis operation is employed to investigate the possible ionic conduction behavior of ceria-carbonate. The other goal is to optimize the processing technology to maximum the kinetics rate for efficient hydrogen production. An impressive current density of 1.2 A cm-2 has been achieved at 600 °C under voltage of 1.6 V at the absolute humidity of 3% and oxygen ionic operational mode.
