摘要：
Gas purging has been a common strategy to improve the possibility of cold start of a proton exchange membrane fuel cell (PEMFC) vehicles. In the present study, water removal in a PEMFC during gas purging after its shutdown is numerically investigated with a transient two-fluid model. The effect of purging gas flow rate on the liquid water and membrane water is explored. The results indicate that the water removal process is not sequential in the sub-regions of PEMFC and the purging gas flow rate affects the overall drying process. (C) 2017 The Authors.
