Abstract
The paper reviews the formation mechanisms and detection methods of flooding and drying faults in proton exchange membrane fuel cells(PEMFCs).Firstly,the causes of flooding and drying faults are analyzed from the perspectives of structure,internal gas transport mechanism and water transport mechanism.Then,the fault detection methods based on modeling,data-driven approaches and direct imaging visualization are comprehensively investigated,and the technical characteristics of these diagnostic methods are deeply analyzed.Finally,considering the limitations and shortcomings of various diagnostic methods,the future improvement and development directions for diagnosing flooding and drying faults in PEMFCs are discussed.This includes utilizing technologies such as miniaturization and portability of electrochemical impedance spectroscopy(EIS)analysis equipment,improving battery model parameters and sharing battery fault big data.
