Pore network modeling of fibrous gas diffusion layers for polymer electrolyte membrane fuel cells
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 ...
In-plane and through-plane gas permeability of carbon fiber electrode backing layers
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 ...
Direct measurement of the capillary pressure characteristics of water-air-gas diffusion layer systems for PEM fuel cells
A method and apparatus for measuring the relationship between air-water capillary pressure and water saturation in PEMFC gas diffusion layers is described. Capillary pressure data for water injection and withdrawal from ...
Wettability and capillary behavior of fibrous gas diffusion media for polymer electrolyte membrane fuel cells
The relationship of capillary pressure to liquid saturation for the water-air fluid pair in two different types of gas diffusion media (GDM) used in polymer electrolyte membrane fuel cell (PEMFC) electrodes is elucidated. ...
On the role of the microporous layer in PEMFC operation
The condition of liquid water breakthrough at the cathode of polymer electrolyte fuel cells (PEMFC) is studied experimentally and data on corresponding water saturation and capillary pressure are provided for gas diffusion ...
