Air-Cooled PEMFC Temperature Cooperative Control and Low Temperature Operation

This paper studies the relationship between the optimal operating temperature of the air-cooled PEMFC stack and the ambient temperature, humidity and operating current through experiments. The air-cooled fuel cell voltage model, stack temperature model and working chamber model are established. A collaborative control system based on fuzzy PID stack temperature and working chamber temperature based on BP neural network is designed, and the control effect of the control system in low temperature environment is verified by simulation experiments.
