Aprotic Li–O2 cells: Gas diffusion layer (GDL) as catalyst free cathode and tetraglyme/LiClO4 as electrolyte

Solid State Ionics, 2014
Abstract High performing Li–O 2 cells are assembled using a commercially available gas diffusion layer (GDL) as catalyst free cathode and tetraglyme/LiClO 4 as aprotic electrolyte, and their electrochemical performances are investigated. The potential/time bound electrochemical characterization at different discharge rates and depths is performed ...

A fractal model for predicting permeability and liquid water relative permeability in the gas diffusion layer (GDL) of PEMFCs

Journal of Power Sources, 2007
In this study, a fractal model is developed to predict the permeability and liquid water relative permeability of the GDL (TGP-H-120 carbon paper) in proton exchange membrane fuel cells (PEMFCs), based on the micrographs (by SEM, i.e. scanning electron microscope) of the TGP-H-120.

A Study on the Evaluation of Effective Properties of Randomly Distributed Gas Diffusion Layer (GDL) Tissues with Different Compression Ratios [PDF]

Applied Sciences (Switzerland), 2020
The gas diffusion layer (GDL) typically consists of a thin layer of carbon fiber paper, carbon cloth or nonwoven and has numerous pores. The GDL plays an important role that determines the performance of the fuel cell. It is a medium through which hydrogen and oxygen are transferred and serves as a passage through which water, generated by the ...

Microstructure-property relationships in a gas diffusion layer (GDL) for Polymer Electrolyte Fuel Cells, Part II: pressure-induced water injection and liquid permeability [PDF]

Electrochimica Acta, 2017
The performance of polymer electrolyte fuel cells (PEFC) strongly depends on a controlled water management within the porous layers. For this purpose we investigate liquid water transport in a commercial gas diffusion layer (SGL 25BA) on the pore scale. X-ray tomography experiments combined with pressure-induced water injection provide 3D images of the

Effects of gas diffusion layer (GDL) and micro porous layer (MPL) on cathode performance in microbial fuel cells (MFCs)

International Journal of Hydrogen Energy, 2011
This study focused on novel cathode structures to increase power generation and organic substrate removal in microbial fuel cells (MFCs). Three types of cathode structures, including two-layer (gas diffusion layer (GDL) and catalyst layer (CL)), three-layer (GDL, micro porous layer (MPL) and CL), and multi-layer (GDL, CL, carbon based layer (CBL) and ...

Overlaid Conductive Silver Nanowire Networks on Gas Diffusion Electrodes for High-Performance Electrochemical CO₂-to-C₂₊ Conversion. [PDF]

Adv Sci (Weinh)
This work presents a rational electrode design for electrochemical CO2 reduction, employing Ag nanowire networks as both current collectors and tandem catalysts. The Ag nanowires are deposited onto the catalyst layer, forming a stacked PTFE/catalyst/Ag nanowires configuration.

Numerical Study on the Effect of Gas Diffusion Layer (GDL) Properties in Cathode on the Performance of Polymer Electrolyte Membrane Fuel Cell (PEMFC)

Korean Chemical Engineering Research, 2012
In this study, the effect of properties of gas diffusion layer (GDL) on the performance of polymer electro- lyte membrane fuel cell (PEMFC) was investigated using the numerical simulation. The multi-phase mixture (M 2 ) model was used to calculate liquid water saturation and oxygen concentration in GDL.
