... of the gas diffusion layer (GDL) and the bipolar plate. Here, we present thermal contact resistance measurements of carbon paper and carbon cloth GDLs over a pressure range of 0.7–14.5 MPa. Contact resistances are highly dependent upon the clamping pressure applied to a fuel cell, and in the present work...

...Younés Faydi; Remy Lachat; Philippe Lesage; Yann Meyer In a proton exchange membrane fuel cell (PEMFC), gas diffusion layers (GDLs) play a major role in the overall system performances. This is the reason why many research investigations try to model and optimize the GDL physical properties...

...B. R. Friess; M. Hoorfar One of the major problems of current proton exchange membrane (PEM) fuel cells is water management. The gas diffusion layer (GDL) of the fuel cell plays an important role in water management since humidification and water removal are both achieved through the GDL. Various...

...Peiyun Yi; Linfa Peng; Xinmin Lai; Jun Ni Gas diffusion layer (GDL) is one of the critical components in proton exchange membrane fuel cells (PEMFCs) and plays several important roles, such as structural support, reactants permeation, water removal, electrons, and heat conduction. The assembly...
