摘要
鉴于天然气、煤炭、石油等传统燃料燃烧面临的能源危机和环境挑战,发展新型可持续能源是我国实现“双碳”目标的必经之路。氢能因能量密度高、高效、清洁而备受瞩目。电解水制氢具有工艺简单、氢气纯度高等优点。在H2制备技术中,利用可再生能源供能的固体氧化物电解槽(SOEC)因具有高效和环保的特点而备受关注。传统氧离子导体固体氧化物电解池(O-SOEC)的发展受到工作温度过高等问题的限制,质子传导型固体氧化物电解池(H-SOEC)具有明显优势。总结H-SOEC电解质、氢电极与空气电极的材料,分析了不同水电解制氢技术的效率及影响电解效率的因素。在已有研究的基础上,指出了H-SOEC发展中存在的问题,并展望了今后的研发方向。
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.
