The proposed hybrid system is composed of a proton exchange membrane fuel cell (PEMFC), solar panels, secondary battery sets, and chemical hydrogen production, to provide sustainable power for EVs. First, the PEMFC consists complicated electrochemistry reactions. However, from the system point of view, we can consider the PEMFC as linear models and regard the un-modelled dynamics as system uncertainties. Therefore, we can apply advanced control algorithms to improve system performance and efficiency. For example, our previous studies confirm that robust control can effectively reduce the hydrogen consumption and improve PEMFC performance. Second, the solar cells can transfer solar power to electricity. Therefore, we will implement solar panels to supply auxiliary power to the EVs. The solar power can be used to drive the vehicle and to charge the secondary battery when the motor load is low, and be used as auxiliary power when the load is high. Third, we will use secondary battery sets to balance the power supplies and loads. We will design a serial-parallel power train, and design suitable power management strategies for the EVs. Fourth, we plan to build a chemical hydrogen production system. Because the hydrogen delivery and storage of large volume is still a problem, the development of PEMFC EVs needs to depend on the corresponding infrastructure. Therefore, we plan to a self-sustainable hydrogen system for EVs. We will use sodium borohydride (NaBH4) to produce sufficient hydrogen for the hybrid system by batch-production procedures. Last, we will integrate the system and build a SimPowerSystem model to verify the system performance. The developed simulation model can also be used for component optimization. This project will apply practical EVs’ loading cycles for performance verification. We will use the simulation model to adjust the system components, and apply a load-meter for in-lab tests. Finally, we will integrate the hybrid-power EVs for road tests and system demonstration.燃料電池太陽能二次電池化學產氫電動車混合電力系統PEMFCsolar panelssecondary batterychemical hydrogen productionelectric vehicleshybrid power system
