摘　　要： 针对质子交换膜燃料电池(PEMFC)阴极侧的氮向阳极侧扩散,并在阳极侧累积的问题,文章提出一种基于模糊控制的阳极氮管理策略。该策略克服质子交换膜燃料电池阳极氮浓度变化大惯性的特点,采用模糊控制,并使用估计模型的估计结果作为输入变量,并以模糊控制器的输出控制燃料电池氢气路尾排动作,控制阳极侧的氮浓度在阈值范围内。该控制模型具有模型简单实用,控制策略易于表格化,且鲁棒性强等优点。仿真结果证明了该策略的有效性。 Aimed at the cross - over and built - up of Nitrogen from anode to cathode, a Nitrogen of anode management strategy is proposed based on fuzzy control. This strategy overcomes the characteris- tics of the large inertia of the anode nitrogen concentration of the proton exchange membrane fuel cell and uses the estimated result of the estimation model as the input variable to control the fuel cell hydrogen row tail action with the output of the fuzzy controller. So the anode nitrogen concentration is within the threshold range. The control model has the advantages of simple and practical model, easy tabularization for the con- trol strategy and strong robustness. The simulation results show the effectiveness of the strategy.
