Research on the Output Voltage of PEMFC System Based on Dual-Mode Control

Because the system of proton-exchange membrane fuel cells (PEMFC) is non-linear, time-varying and high-level, a new control arithmetic is presented based on the adaptive neuro-fuzzy inference system-PID (ANFIS-PID) and a correlative dual-mode control system is designed. The affection of the temperature and reactive gas pressure on the stack performance are analyzed. The system is established by mat lab software and compared with PID controller. The simulation result proves that the new method excels the conventional arithmetic in rapidity.
