中文摘要

在质子交换膜燃料电池(PEMFC)寿命周期内,电堆内部各单体电池间会出现性能不一致性。特定电池因老化或局部故障(如干涸)导致电压下降,进而引发局部过热及性能进一步恶化。本文针对该问题,设计并建模了一种用于燃料电池能量管理系统的均衡器,旨在提升电堆运行的均衡性与可靠性。

English Abstract

During the lifespan of a polymer electrolyte membrane fuel cell (PEMFC) system, some heterogeneities between the cells constituting the stack can appear. The voltage of one particular cell in a stack may decrease because of specific aging or local malfunctioning such as drying. As a result, more heat is generated in this cell leading to an increase in its temperature and, thus, an additional volta...
