基于PEMFC电压均衡性的OER测试研究

The OER Test Research for the Voltage Balan of PEMFC

用水冷型质子交换膜燃料电池作为参考,用CFD模拟质子交换膜燃料电池阴极流场,同时建立质子交换膜燃料电池的集总参数模型,来验证电堆单片电池电压的均衡性,并得到了不同输出电流条件下电压均衡性最优时所对应的过氧比(OER).对在实际应用中通过控制电堆阴极侧的空气进气量改善电压均衡性与电堆性能、延长电堆寿命提供指导和参考依据.

In this paper,referring to water-cooled proton exchange membrane fuel cell（PEMFC）,the cathode flow field in PEMFC was simulated by CFD.While,using a lumped parameter model of PEMCF to verify the balance of single chip voltage,and work out the OER Corresponding to the best Status of Voltage balancing with different output currents.In the practical work,the conclusion can conduce to improve the voltage balance,fuel cell performance and battery lifetime with controlling the air volume.
