Fluid flow modeling in a sulfonated cation-exchange membrane García Villaluenga, Juan Pedro Barragán García, Vicenta María Izquierdo Gil, María Amparo Godino Gómez, María Paz Seoane Rodríguez, Benjamín Ruiz Bauzá, Carlos 536 Methanol Fuel-Cells Transport-Properties Water-Uptake Ion Nafion Permeation Sorption Behavior State Termodinámica 2213 Termodinámica © 2009 Wiley Periodicals, Inc. Sponsor: Comunidad de Madrid and Universidad Complutense de Madrid; contract grant number: CCG06–UCM/MAT–1037. Liquid permeation measurements of water, methanol, and 2-propanol were carried out using a commercial cation-exchange membrane Nafion-117 (perfluorinated polyethylene with pendant ether-linked side chains terminated with sulfonated groups). The experimental permeation data are treated and analyzed using the capillary model, leading to the determination of equivalent pore radius of the membrane structure.
