We have introduced theIonic conductivityof perfluorinated acid membranes for analyze the polymer/water systems with structure effect for fuel cells. We proposed a molecular thermodynamic framework to describeIonic conductivityof polymer membrane solutions. To understand the membrane/water behavior, in this study, we develop a lattice model for polymer-solvent system, Lattice Cluster Theory (LCT). To takeintoaccountthe highly oriented interactions between segments, the proposed model requires an additional parameter (δε/k) related to the energy of the oriented interaction.We finallyproposed the total cell voltage model for PEMFC with our work. |
