Abstract

The main objective of this study is to address the susceptibility of fuel cell thermal management systems to disturbances such as load demand fluctuations, which typically result in temperature variations with inherent delays. In the waste heat recovery mode, the optimal power distribution of the pump and fan is achieved by using genetic algorithm. This setup was then managed via an Active Disturbance Rejection Control (ADRC) feedback mechanism, aimed at optimizing system energy consumption. The results demonstrated that the average temperature of the Proton Exchange Membrane Fuel Cell (PEMFC) stack was maintained at 70°C, with an inlet and outlet temperature difference of less than 10°C, satisfying system requirements. The energy consumption of the PEMFC thermal management was reduced by 43.6% with the energy-optimized ADRC algorithm compared to the PID algorithm.
