Application of atomic force microscopy in the surface/interface phenomena of proton exchange membrane fuel cells

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.
