Liquid water management plays a significant role in proton exchange membrane fuel cell (PEMFC) performance especially when the PEMFC is operating with high current density Therefore understanding of liquid water behavior and flooding process is a critical challenge that must be addressed To overcome PEMFC durability problems a liquid water flooding process is studied in the cathode side of a PEMFC with straight parallel channels and a porous layer using FLUENT (R) v6 3 26 software with a volume-of-fluid (VOF) algorithm and user-defined-function (UDF) The general process of liquid water flooding within this type of PEMFC cathode is investigated by analyzing the behavior of liquid water in porous layer and gas flow channels Two important phenomena the first channel phenomenon and the last channel phenomenon and their effects on the flow distribution along different parallel channels are discussed (C) 2010 Elsevier B V All rights reserved
