摘　　要：质子交换膜燃料电池长期运行时,电压随时间的变化存在两个振荡区域,即:A区———电压平稳振荡区和B区———电压下降振荡区。上述两个电压振荡区域和电池的水管理有关,综述了现有研究对于这两个振荡区域的理论解释,但对于其中的机理和变化规律有待进一步通过设计专门的实验来验证。There exist two voltage oscillation areas during the long-term operation of a PEMFC, i.e., district A： the stable oscillation area of voltage and district B： the drop oscillation area of voltage. Both of these two oscillation areas are related to the water management inside a fuel cell. The existing researches were reviewed, in which the two oscillation areas were recorded. However, special experiments should be designed to verify the mechanisms and change laws of these two areas.
