Abstract:

This paper reviews the principles and characteristics of the atomic force microscopy (AFM) technique and its applications in the research of surface/interface phenomena of proton exchange membrane fuel cells (PEMFCs), elaborates the use of multiple modes of AFM to characterize the surface properties, interface structure, proton conduction mechanism and electrochemical activity of proton exchange membrane and catalyst layer. In addition, AFM can monitor the electrochemical reaction process in fuel cell working conditions and observe the electrochemical behavior of PEMFCs in real time. As a result, AFM is an effective technique for the study of the proton conduction mechanism and electrochemical activity in PEMFCs. AFM studies may have guiding significance for the synthesis and modification of proton exchange membranes, electrocatalysts and other key materials, showing bright prospects for the study and improvement of PEMFCs.

Key words: atomic force microscope, fuel cell, proton exchange membranes, catalyst

摘要:

综述了原子力显微镜(AFM)的技术特点及其在质子交换膜燃料电池(PEMFCs)表/界面现象研究中的应用,总结了利用AFM多种模式表征质子交换膜和催化层的表面性质、界面结构、质子传导机理以及电化学活性方面的研究进展。除此之外,AFM可以在燃料电池工作条件下对电化学反应过程进行监控, 实时观察PEMFCs中的电化学行为,是研究PEMFCs中质子传导机理和电化学活性的一种有效手段。AFM研究对质子交换膜的合成与改性具有一定的指导意义,同时也为催化剂等其他关键材料的制备提供了参考,为PEMFCs中电化学反应过程的研究开辟了更多的方向,具有良好的发展前景。
