基于模糊模式的质子交换膜燃料电池水管理控制

Water Management Control of PEMFC Based on Fuzzy Mode

针对质子交换膜燃料电池(Proton Exchange Membrane Fuel Cell,PEMFC)内部水的产生和去向,给出了实现湿度控制的平衡公式。受测量精度及环境等复杂因素的影响,采用普通控制方法难以实现精确控制,为此,采用基于模糊模式的控制方法对PEMFC系统内部湿度进行控制,解决了系统控制耦合性问题,实现了不同功率下系统内部水平衡,并通过实验验证了该控制方法的合理性。

Aiming at water generation and flow direction of Proton Exchange Membrane Fuel Cell( PEMFC),a balance expression of humidity control is proposed. Because of the influence of measure precision,environment and many other complicated factors,using common control methods can't achieve precise control. This paper regulates humidity of PEMFC system basing on fuzzy mode control method,solves the coupling and uncertainty problem of system control,achieves water balance in different power level,and validates the feasibility of this control method by experiments.
