Abstract

A parametric analysis of a model equation developed to predict the cell voltage versus current density response of a liquid feed direct methanol fuel cell is presented. The equation is based on a semi-empirical approach in which methanol oxidation and oxygen reduction kinetics are combined with effective mass transport coefficients for the fuel cell electrodes. The model equation is applied to experimental data for a small-scale fuel cell and produces electrochemical parameters generally consistent with those expected for the individual components of the fuel cell MEA. The parameters thus determined are also used in the model to predict the performance of a DMFC with a new membrane electrode assembly. © 2006 Elsevier B.V. All rights reserved.
