Power Management of PEM Fuel Cell Hybrid Systems

  In this paper,a power management algorithm of PEM fuel cell hybrid system is proposed.Since the PEM fuel cell cannot response to fast load change,a rechargeable lithium-ion battery pack and two DC/DC converters are added to build a PEM fuel cell hybrid system to solve this problem.By utilizing a virtual potential field approach,a power coordinating algorithm is proposed to manage the power demand for the PEM fuel cell and the lithium-ion battery to respond to the dynamically changed power load while maintaining the lithium-ion batterys state of charge(SOC).As the SOC of the battery cannot be measured directly,a nonlinear observer based on an inclusive battery model is utilized for the SOC estimation.Simulation results are provided to illustrate the performance of the power management method.
