Aerospace Power Scholarly Research Program. Delivery Order 0013: Volume 2 - Flux Equations for a Direct Methanol Fuel Cell Solid Polymer Electrolyte Membrane

Abstract

This second volume, of a two volume report, consists of the derivation of the transport flux equations for a direct methanol fuel cell solid polymer electrolyte membrane using (1) moderately dilute solution theory based on Fickian diffusion, (2) concentrated solution theory based on the generalized Stefan-Maxwell equations, and (3) concentrated solution theory based on the Onsager irreversible thermodynamics approach to transport processes. In very dilute to very concentrated solutions, the developed equations can be used to help determine the transport properties of a membrane such as permeability of the fluid mixture and effective mass diffusivities of the various species.
