Impact of Gas Diffusion Layers (GDLs) on Water Transport in PEFCs

Journal of The Electrochemical Society, 2011
The gas diffusion layer (GDL) is a critical component for water management in PEFCs (Polymer Electrolyte Fuel Cells). The impact of anode GDLs and the hydrophobic/hydrophilic nature of GDLs were studied in order to determine the effect of water transport on membrane-electrode assembly (MEA) performance.
