摘要
质子交换膜燃料电池系统开启和关闭策略的设定对于燃料电池系统的运行有着至关重要的作用。为此,通过设定不同的燃料电池系统开启和关闭的组合策略,探讨启停策略对质子交换膜燃料电池系统的影响。燃料电池单体最高开路电压和燃料电池输出电压是质子交换膜燃料电池系统中十分重要的数据,这2个数据值很大程度上反映燃料电池的性能状况。基于实验室自主搭建的燃料电池系统平台,利用巡检系统监测燃料电池单体的最高开路电压。通过比较不同的启停策略发现,避免氢/空界面、催化剂脱落和氧渗透等工况的发生有助于延长电池寿命。
The setting of proton exchange membrane fuel cell system startup and shutdown strategy has an important effect on the fuel cell operation performance.In this paper,the influence of fuel cell system startup and shutdown strategies was explored by designing different fuel cell system startup and shutdown processes.The maximum single cell’s voltage and fuel cell’s open circuit voltage are the important research parts for fuel cell system in this experiment which can reflect the proton exchange membrane fuel cell operation performance.The maximum single cell’s voltage was measured by Fuel Cell Voltage Monitor System(CVM)based on the fuel cell system set-up which was built independently.By comparing different start-up and stop strategies,it is concluded that avoiding hydrogen/air interface,catalyst shedding and oxygen penetration can help to prolong battery life.
