| dc.description.abstract | In this study, water removal is observed through a transparent fuel cell, and the relationships between it and the responses of voltage and impedance are analyzed. The water flows in the channel are accompanied by voltage soaring. For all studied cases, water flow appearances increase as GDL flooding is induced by supplying more vapor; for example, under a stoichiometry ratio of 2.0, the number of water flow appearances is 0, 3, and 25 for 1800 s as relative humidity increase to 30, 50, and 100%. The average voltage is calculated, and a positive relationship between it and the frequency of water flows is determined. The results reveal that frequent flooding-induced water removal could be one strategy to enhance fuel cell performance. (c) 2021 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
