Aiming at the problem that the performance degradation of PEMFC during operation is not considered in the current control research
and it is difficult to solve the problem of life degradation of PEMFC under different working conditions
we put forward a control strategy to delay battery degradation. Firstly
the voltage degradation curves under steady-state and dynamic conditions are obtained by predicting the life of the fuel cell. Then
on the basis of calculating the predicted voltage degradation rate
the reference voltage degradation rate satisfying the stable operation of the battery is set. The PID iterative learning control algorithm is introduced to control the inlet pressure of the fuel cell to achieve the goal of tracking the reference voltage degradation rate of the battery and achieve the purpose of slowing down the voltage attenuation. Finally
the delayed degradation control response of PEMFC under steady-state and dynamic cycle conditions is verified by MATLAB/Simulink simulation. The results show that the designed PEMFC control strategy based on multi-condition life prediction can be adopted to effectively delay the voltage degradation rate of PEMFC system under steady-state and dynamic conditions
