摘　　要：基于一个准确高效的多相多维数值计算模型,在充分考虑水的凝结/蒸发以及结冰/融化等相变过程的基础上,仔细分析了质子交换膜燃料电池在常温下的瞬态响应现象和低温环境下的冷启动现象这两种瞬态变化过程,讨论了其中的关键影响参数及其作用机理。A multi-phase multi-dimensional PEM fuel cell model with consideration of water condensation/ evaporation and freezing/melting processes was presented within a mixed-domain framework. The model was employed for numerical studies of the transient responses and cold-start processes of PEM fuel cells. The key parameters dictating these transient phenomena were carefully reviewed.
