Abstract
The objective of this work is to evaluate the multiphase transport characteristics of diffusion media (DM) of polymer electrolyte fuel cells (PEFCs) using advanced microstructure quantification and pore-scale modeling techniques. The microstructure of a gas diffusion layer (GDL) sample is characterized using micro x-ray computed tomography. The microstructure dataset is analyzed using in-house structural analysis tools and a full pore morphology model to determine the water imbibition characteristics and key measures of structure, including the porosity, pore (void) connectivity, tortuosity, and capillary pressure-saturation curves.
