... resistance in the cathode and negatively impacted the cell performance slightly. The cathode air or oxygen flow may not need to be fully hydrated, and the cathode MPL was less critical for water management since the liquid water supplied from the anode methanol solution could hydrate the PEM...

...Yong-Song Chen; Huei Peng Water management in a fuel cell is essential to ensure cell performance and life. In this study, a special single cell was designed for the purpose of detecting liquid water and water vapor simultaneously. The major difference between our design and traditional flow field...

...Kui Jiao; Biao Zhou Liquid water transport inside proton exchange membrane (PEM) fuel cells is one of the key challenges for water management in a PEM fuel cell. Investigation of the air-water flow patterns inside fuel cell gas flow channels with gas diffusion layer (GDL) would provide valuable...
