Abstract

To address the issue of temperature dynamic modeling and control for proton exchange membrane electrolyzer cell （PEMEC）,a 50 kW PEMEC voltage model is developed with a modeling error of less than 2.95%. Based on this model, thermal management and efficiency models of the electrolyzer are further established. Furthermore, based on the concept of variable universe, a variable universe fuzzy PID controller was designed to regulate the external energy exchange of the electrolyzer cell, ensuring its operation at the target temperature. Finally, verification was conducted on a hardware-in-the-loop real-time simulation platform under various test conditions including load disturbances and parameter variations. Compared to traditional PID control and fuzzy PID control, the variable domain fuzzy PID control demonstrated a reduction in adjustment time of at least 10.3% and a minimum reduction of 7.1% in the maximum temperature deviation. These results indicate that the variable domain fuzzy PID controller not only offers faster dynamic response but also demonstrates greater robustness.
