Abstract:

Since traditional fossil fuels,such as nature gas,coal and petrol oil,have brought energy crisis and environment pollutant to our society, renewable energy becomes the solution to realization "dual carbon" goals. Hydrogen energy attracts much attention because of its high energy density, high efficiency and environmental protection. Hydrogen production from water electrolysis is of simple operation process and high purity product. Hydrogen production technology in solid oxide electrolytic cells(SOECs) powered by new energy attract much attention because of its high efficiency and low environment impact. Compared to the traditional oxygen-ion solid oxide electrolysis cells(O-SOECs)whose development is hampered by narrow operation temperature range,proton-conducting solid oxide electrolysis cells(H-SOECs)are of better performances. Based on the summary on the materials applied to the electrolyte, hydrogen electrodes and air electrodes of H-SOECs, the efficiency of different hydrogen production by water electrolysis technologies and the factors affecting their electrolysis are analyzed. Based on the research progress made on H-SOECs, the existing problems and challenges of the technologies are proposed.

Key words: solid oxide electrolytic cell, hydrogen production by water electrolysis, proton conduction, energy storage, Faradaic efficiency, new energy, carbon neutrality, perovskite
