- Proton exchange membrane fuel cell (PEMFC) is widely used in transportation and high-efficiency energy systems for their high power density and rapid start-up capability. The temperature control of its thermal management system is characterized by slow response and system oscillation, and the temperature control process suffers from problems such as large temperature fluctuations and slow temperature rise during cold starts. To effectively control the fuel cell thermal management system, this paper proposes a fuzzy PID-based control strategy to optimize the temperature control of the stack by comprehensively controlling the cooling fan, thermostat, temperature control valve, and heat components. By modeling the 60kW PEMFC thermal management system on the MATLAB/Simulink platform, the flow distribution and heat exchange of each component are analyzed and the optimized fuzzy control strategy is compared with the traditional PID control strategy. The simulation results show that the control strategy can effectively decouple the cooling fan and circulating water pump and achieve accurate temperature control under different working conditions.
