| 摘 要： | 质子交换膜燃料电池(PEMFC)具有发电效率高、运行温度低、启动速度快、结构简单、可靠性高等优点,基于其优点近几年得到了快速的发展。由于工作时水汽渗透作用,导致阳极惰性气体和水的积累,其长时间无法排出将降低电堆的性能以及使用寿命。文章给出了脉冲式尾排策略的优化方向,可以有效排出尾气,提高燃料利用率,从而保证PEMFC的性能。

| Abstract: | Proton exchange membrane fuel cell(PEMFC)has the advantages of high power generation efficiency,low operating temperature,fast start-up speed,high reliability and simple structure.Based on its advantages,it has been developed rapidly in recent years.Due to the crossover effect,the inert gas and water will be accumulated in the anode.If they can not be drained out of the system,the performance and the lifetime will be affected.In this paper,the optimization of impulse tailrace strategy is presented,which can effectively discharge tail gas and improve fuel efficiency,thus ensuring the performance of PEMFC. |
