Abstract:
In this work, a comprehensive study on the dynamic modeling and control of the reformed methanol high-temperature proton exchange membrane fuel cell (HT-PEMFC) and battery system is presented for electrical applications. A more detailed mathematical model that considers the transient dynamics of the fuel cell is adopted, providing a simplified yet accurate solution for a wide range of fuel cell operational cases. The dynamic system model incorporates the FC, balance of plan (BoP) components, buck/boost converter, and battery. The buck/boost converter operation mode is automatically switched by power management rules according to the battery voltage, achieving coordination between the FC and the battery, stable DC bus voltage, and a healthy state-of-charge (SOC) level of the battery. Simulations are conduction on MATLAB/Simulink and the results validate the effectiveness of the proposed modeling approach and power sharing strategy in achieving enhanced performance and system stability under different load cases. The research contributes for integrating HT-PEMFC systems in future electrical applications.
