适当的气体和水管理对于在 PEM 燃料电池堆中实现和维持高功率输出至关重要。先前对小型氧燃料电池堆的实验表明，使用主动气体管理（AGM）系统来控制单独的排气可以改善并维持氧气操作的高功率。活性气体管理系统现已应用于五节和六节电池的小型和大型空气阴极堆中。 AGM 系统的使用将小型五芯电池堆的功率输出从 38.4 W 增加到 50.4 W，将大型六芯电池堆的功率输出从 260 W 增加到 350 W。在考虑寄生损耗后，大型和小型电池堆的功率均增加了 30%。 (C) 2004 Elsevier B.V. 保留所有权利。
Proper gas and water management are essential to achieving and maintaining high power output in a PEM fuel cell stack. Previous experimentation with a small oxygen fuel cell stack has demonstrated that the use of an active gas management (AGM) system to control individual exhausts improved and sustained high power with oxygen operation. The active gas management system has now been employed in small and large air cathode stacks of five and six cells. The use of the AGM system increased the small five-cell stack's power output from 38.4 to 50.4 W and increased the large six-cell stack's power output from 260 to 350 W. Both large and small stack's demonstrated a 30% power increase after accounting for parasitic losses. (C) 2004 Elsevier B.V. All rights reserved.
