摘　　要：燃料电池堆单片电压一致性是电堆工作性能好坏的重要指标之一,单片电压一致性较高,电堆性能以及稳定性较好。由于操作参数、结构以及材料等因素影响,目前燃料电池堆单片电压一致性不是很理想,特别在大电流、水热分布不均、动载荷以及长时间运行时电压一致性明显变差。介绍了单片电压一致性的评价标准以及目前的研究进展,对燃料电池堆单片电压一致性的未来发展趋势进行了总结。Individual cell voltage uniformity of the fuel cell stack was one of the important operating conditions of the fuel cell. According to the research, the performance of the fuel cell increased as the individual cell voltage uniformity increases. However, because of the limit of the operating parameters, the structure of the fuel cell and the material, the present individual cell voltage uniformity was not satisfied, especially under the condition of large current, water and heat nonuniform distribution, dynamic load and long time running. The evaluation standard of individual cell voltage uniformity was introduced, and the recent research progress was reviewed. What＇s more, the future development of the individual cell voltage uniformity was summarized.
