Abstract
- As an important renewable energy, hydrogen energy becomes an important part of the future energy system. Proton ceramic electrolysis cell (PCEC) enables the efficient, clean, large-scale preparation of hydrogen, which is a new type of energy conversion device, attracting the attention of many researchers. Sr 2 Fe 1.4 Zn 0.1 Mo 0.5 O 6-δ (SFZM) anode materials were developed to investigate the effect of B-site doping of Zn on the electrochemical properties of the Sr 2 Fe 1.5 Mo 0.5 O 6-δ (SFM) materials. The results reveal that the doping of Zn increases the concentration of oxygen vacancies and improves the electrocatalytic activity, which in turn improves the performance of the material. A current density of 408 mA cm−2 has been achieved at 1.3 V when the SFZM-based single cell was operated in an electrolysis mode (50% H 2 O in air) at 600 °C, higher than SFM-based single cells (286 mA cm−2 at 1.3 V). In addition, the SFZM-based single cell exhibited good durability in a stability test at an electrolysis current density of 408 mA cm−2. This work confirms that SFZM is a promising material for proton ceramic electrolysis cell anode. [ABSTRACT FROM AUTHOR]
