Implications of inherent inhomogeneities in thin carbon fiber-based gas diffusion layers: A comparative modeling study
(Elsevier, 2019-02-01)Thin porous media are present in multiple electrochemical energy devices, where they provide key transport and structural functions. The prototypical example is gas diffusion layers (GDLs) in polymer-electrolyte fuel cells ... -
In-plane and through-plane gas permeability of carbon fiber electrode backing layers
(Elsevier, 2006-11-08)The absolute gas permeability of several common gas diffusion layer (GDL) materials for polymer electrolyte membrane fuel cells was measured. Measurements were made in three perpendicular directions to investigate anisotropic ... -
Measurement and Characterization of Heat and Mass Diffusion in PEMFC Porous Media
(University of Waterloo, 2012-09-19)A single polymer electrolyte membrane fuel cell (PEMFC) is comprised of several sub-millimetre thick layers of varying porosity sandwiched together. The thickness of each layer, which typically ranges from 10 to 200μm, is ... -
Pore network modeling of fibrous gas diffusion layers for polymer electrolyte membrane fuel cells
(Elsevier, 2007-11-08)A pore network model of the gas diffusion layer (GDL) in a polymer electrolyte membrane fuel cell is developed and validated. The model idealizes the GDL as a regular cubic network of pore bodies and pore throats following ... -
Serial Compression Effects on Porosity, Diffusion, Permeability, and Water Droplet Contact Angle of the Gas Diffusion Layer in Polymer Electrolyte Membrane Fuel Cells
(University of Waterloo, 2020-05-14)The polymer electrolyte membrane (PEM) fuel cell is an electrochemical device that directly converts the chemical energy of hydrogen and oxygen into electricity with water and heat as byproducts. It is very promising to ...
