| Abstract: | 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. |
