Water management in proton exchange membrane (PEM) fuel cells, ie, balance between
membrane drying and liquid water flooding, is a major aspect in the operation of these …

Excess of liquid water in gas channels of polymer electrolyte fuel cells is responsible for
malfunctioning of these devices. Not only it decreases their efficiency via partial blockage of …

Understanding the two-phase distribution characteristics within the multi-gas channel of a
fuel cell is important for improving fuel cell performance. In the paper, the volume of fluid …

Thin porous layers, that have large aspect ratios, are seen in many applications such as
hydrogen fuel cells and hygiene products, in which air-water immiscible flow is of great …

The pore-scale modeling is a powerful tool for increasing our understanding of water
transport in the fibrous gas diffusion layer (GDL) of a polymer electrolyte fuel cell (PEFC). In …

The lattice Boltzmann method is used to simulate the three-dimensional dynamic process of
liquid water breaking through the gas diffusion layer (GDL) in the polymer electrolyte …

The droplet dynamics in the cathode gas flow channel of a hydrogen fuel cell has been
numerically investigated to obtain ideas for designing a flow channel to effectively prevent …

The objective of this work is the development of model concepts and methods for the
coupling of free flow and flow in porous media. Coupling concepts of varying complexity …

Water transport and heat transfer are two critical issues for proton exchange membrane fuel
cell (PEMFC) commercialization. Proper water and heat management ensure a sufficient …

Water in the gas channels of a Proton Exchange Membrane Fuel Cell is modeled as slugs
and film, and removal mechanisms for these flow patterns are numerically investigated. The …
