摘要

Proton exchange membrane fuel cell (PEMFC) is a new type of clean and efficient fuel cell with wonderful prospect. In consideration of the key position of power supply in the device, estimating remaining useful life (RUL) of PEMFC has positive effects in its new stages of development. Currently, RUL estimation of industrial facilities has played an extremely important role in the field of high safety and reliability requirements. For practical systems, the state is often a stochastic process with inevitable degradation during the runtime. In truth, a large amount of data about system operation state is available, and the linear stochastic degradation model is widely applicable to stochastic degradation system. In view of this, this paper selects the proton exchange membrane fuel cell as an object of study, and the remaining useful life is estimated based on its monitoring data. At first, a brief introduction to proton exchange membrane fuel cell is covered. Then, the stochastic degradation model is built and the method of predicting the remaining life is given. At last, the RUL predicted value is obtained and the feasibility of the method is verified by the simulation results with high precision.
