On Modeling Water Transport in Polymer Electrolyte Membrane Fuel Cell by Ahmed Kaffel* in Open Access Biostatistics &Bioinformatics

There is a great need to predict liquid water saturation in porous layers such as gas diffusion layers (GDL) and micro porous layers (MPL) of polymer electrolyte membrane fuel cells (PEMFCs) as this is a key parameter in flooding occurrence which is a limiting factor of PEM fuel cell performance. Several models have been developed in order to study water distribution and migration in micro porous layers. These models require heavy computational efforts and doubt in their applicability to the gas diffusion layer (GDL). Recently Qin & Hassanizadeh [1] developed a new approach based on the reduced continua model for modeling multiphase flow through a stack of thin porous layers. Their  approach requires much less computational efforts and predicts less water flooding in the GDL, but is using an empirical closure inaccurate model.
