旁通阀结构对燃料电池系统阴极压力控制效果的分析
Analysis of the Effect of Bypass Valve Structure on Cathode Pressure Control in Fuel Cell Systems
摘要
Abstract
In order to reduce the adverse effects of pressure fluctuations on the service life of fuel cells,the effectiveness of adding a bypass valve to control pressure fluctuations was investigated through simulation and comparative experiments.Based on the analysis of the fuel cell output characteristics and operating principles of each component,the mechanism and control model were established.An inverted decoupling method based on active disturbance rejection was used to achieve decoupling control of flow and pressure.Pressure fluctuation control was implemented using a fuzzy PI control.The effect of decoupling control within this system structure was verified using the Matlab/Simulink platform.The peak pressure fluctuation in the comparative experiments is 1.09 kPa with the bypass valve and 1.82 kPa without the bypass valve respectively.The addition of a bypass valve can reduce pressure fluctuations,thereby increasing the service life of the fuel cell.关键词
