Application of improved fuzzy control algorithm in PEMFC output control

The mathematical model of proton exchange membrane fuel cell(PEMFC) is built by using mechanism modeling method. According to the dynamic characteristics of the output voltage, an improved fuzzy control algorithm is used to regulate control parameters and control rules. The simulation results show that, this kind of improved fuzzy control algorithm can ensure the stability of the output voltage in different load conditions and ensure the reliability and stability of the PEMFC.
