Modeling Water Uptake of Proton Exchange Membranes

Berg P., Promislow K., Simon Fraser University, CA

Water content in Nafion membranes of proton exchange membranes (PEM) is crucial to its functionality. The adsorption of liquid water occurs on a time scale of seconds, while the desorption (drying) time scale is on [...]

Mathematical Modeling of Water Management in PEM Fuel Cells

Berg P., Promislow K., Stockie J., Wetton B., Simon Fraser University, CA

Liquid water is fundamental to Polymer Electrolyte Membrane fuel cells (PEMFC). Its influence, both beneficial and parasitic, is measured on time scales from femto-seconds to hours, on length scales from Angstroms to centimeters. Its role [...]
