This study investigates the effects of the flooding of the gas diffusion layer (GDL), as a result of liquid water accumulation, on the performance of a proton exchange membrane fuel cell (PEMFC). The transient profiles of the current generated by the cell are obtained using the numerical...

A two-phase polymer electrolyte membrane fuel cell model has been developed to investigate transport of species in a gas diffusion layer taking into account effects of liquid water saturation. A set of governing equations for mass, momentum, species concentration involving oxygen, hydrogen,...

Gas diffusion layer (GDL) is an important component of a proton exchange membrane fuel cell (PEMFC) to take part in the interplay of the transport of different species. It has been found that the performance of a PEMFC depends upon the morphology of the GDL. The performance of PEM fuel cell...

The contact resistance between the gas diffusion layer (GDL) and the bipolar plate has been experimentally estimated as they are assembled in proton exchange membrane (PEM) fuel cells. A number of coated and non-coated GDLs, graphite bipolar plates and a sealing gasket were employed to perform...

The effects of the anisotropic bending stiffness of gas diffusion layers (GDLs) on the performance of polymer electrolyte membrane fuel cells with metallic bipolar plates (MBPs), having different channel depths, are investigated. The current–voltage performance of fuel cells with 90° GDLs,...

The present study focuses on the investigation of water dynamics inside a polymer electrolyte membrane fuel cell using two different modelling approaches: Eulerian two-phase mixture and volume of fluid interface tracking models. The Eulerian two-phase mixture model has provided overall...

Fuel cells will be used extensively in the future as renewable energy sources and they are the subject of substantial research. However, various problems are encountered with their mass production, such as the bipolar plate, the flow channel, the catalyst, the membrane electrode assembly (MEA),...

Aluminum has many advantages for commercial bipolar plate of PEM fuel cell such as light weight, low cost and easy manufacturing. However, it has a low corrosion resistance under a PEM fuel cell operation condition that is a special issue of all metal bipolar plates. In this study, polypropylene...
