Modeling of Water Removal from PEM Fuel Cell during Gas Purging

Abstract:

Water removal from polymer electrolyte membrane fuel cell (PEMFC) during gas purging after shutdown is investigated by using a three dimensional two-phase transient model. The effect of initial cell temperature on the drying process of PEMFC is studied. It is found that the initial cell temperature has significant effect on the drying process during gas purging and high initial cell temperature is benificial for water removal.
