| 摘 要： | 建立了闭口氢-氧质子交换膜燃料电池的三维非稳态数学模型,研究了不同操作压力条件下,电池的运行特性及内部各参数的变化情况.结果表明:闭口电池的性能随着运行时间的增加逐渐下降,且阴极侧氧气不足是导致电池衰减的主要原因；在较高的操作压力下,电池可以维持工作更长的时间. |
| 关 键 词： | 闭口 氢-氧电池 非稳态 运行特性 |

| Abstract: | An unsteady-state three-dimension model is addressed to investigate the instantaneous operation characteristics of a closed-end PEMFC. The operating characteristics and parameters variation of the cell under different operating pressures are studied in detail. The results show that the voltage of the cell is declining as the time goes on, the main reason for this situation is the lacking of oxygen in the cathode side. Moreover, the cell can work longer with high voltage by increasing the operating pressure. |
| Keywords: | closed-end H2 / O2 PEMFC unsteady state operating characteristics |
