Review of degradation mechanism and remaining useful life prediction of PEMFC
Remaining useful life prediction is an effective solution to solve the problem of short life and high cost of PEMFC system.In this paper,the degradation mechanism of PEMFC system,including proton exchange membrane,catalytic layer,diffusion layer and oth-er components,was reviewed.The factors influencing the aging of PEMFC system were summarized from intrinsic factors and external fac-tors,especially improper operation in operation and management would accelerate the aging of PEMFC system.The commonly used degra-dation performance indexes to characterize the aging degree of PEMFC were summarized.The selection of degradation performance indexes is of great significance to the research of life prediction.The advantages,disadvantages and applicability of different indexes were intro-duced.Common faults and life prediction were introduced from three aspects:model-driven,data-driven and hybrid-driven.Model-driv-en and data-driven have their own advantages and disadvantages.Hybrid can combine their advantages and improve the precision and ac-curacy of prediction.Finally,the future direction of prediction research was prospected.
