摘要:

氨作为一种理想的储能材料和氢能源载体,其在质子导体固体氧化物电化学装置中的利用与合成可实现高效清洁的发电和储能。本文综述了质子导体固体氧化物电化学装置中氨的利用与合成的实验和理论研究进展,在实验研究方面全面分析了电解质和氨电极材料的开发,在理论研究方面重点讨论了热力学-电化学模型和密度泛函理论(DFT)的研究概况。电解质的质子电导率和氨电极的催化活性是影响电化学装置性能的关键因素,因此开发高质子电导率的电解质和高催化活性的氨电极仍是主要的研究方向。热力学-电化学模型和基于DFT的理论研究可分别为电化学装置的结构设计/运行条件的优化和氨电极材料的开发提供有效指导和思路,但是对于更高层次(三维)的热力学-电化学模型理论研究和氨电极材料上氮气的电化学活化机理的研究仍需加强。最后总结指出了质子导体固体氧化物电化学装置中氨的利用与合成的未来研究方向。

Abstract:

Ammonia is an ideal energy storage material and hydrogen energy carrier. Its utilization and synthesis in proton-conducting solid oxide electrochemical devices can realize efficient and clean power generation and energy storage. In this paper, we review the advances in experimental and theoretical studies on the utilization and synthesis of ammonia in proton-conducting solid oxide electrochemical devices. In the aspect of experimental study, the development of electrolytes and ammonia electrode materials are comprehensively analyzed. While in the aspect of theoretical study, the research progress of thermodynamic-electrochemical models and density functional theory (DFT) are discussed emphatically. Since the proton conductivity of electrolyte materials and the catalytic activity of ammonia electrodes are the critical factors affecting the performance of electrochemical devices, the development of electrolyte materials with high proton conductivity and ammonia electrodes with high catalytic activity are still the main research topics. Thermodynamic-electrochemical models and DFT-based theoretical researches can provide guidance and ideas for the structural design of electrochemical device/optimization of operating conditions and development of ammonia electrode materials, respectively. However, theoretical studies of higher-level (three-dimensional) thermal-electrochemical models and the electrochemical activation mechanism of nitrogen on ammonia electrode materials still deserve further study. Finally, the future research directions of ammonia utilization and synthesis in electrochemical devices are also summarized.

Key words: solid oxide fuel cell, proton-conducting electrochemical reactor, ammonia, ammonia synthesis, ammonia electrode materials
