Abstract
A one dimensional isothermal model is proposed by modelling the kinetics of methanol transport at anode flow channel (AFC), membrane and cathode catalyst layer of direct methanol fuel cell (DMFC). Analytical model is proposed to predict methanol cross-over rate through the electrolyte membrane and cell performance. The model presented in this paper considered methanol diffusion and electrochemical oxidation at the anode and cathode channels. The analytical solution of the proposed model was simulated in a MATLAB environment to obtain the polarization curve and leakage current. The effect of methanol concentration on cell voltage and leakage current is studied. The methanol cross-over has the significant impact on cell performance. The presented model predicts higher leakage current with the increase of methanol feed concentration. The cell performance was predicted at 70°C and various methanol feed concentration. The proposed model was validated with the experimental polarization curve of active DMFC.
期刊介绍:
Journal of Polymer Materials-An International Journal is published quarterly (4 issues per year), which covers broadly most of the important and fundamental areas of Polymer Science and Technology. It reports reviews on current topics and original research results on synthesis of monomers and polymers, polymer analysis, characterization and testing, properties of polymers, structure-property relation, polymer processing and fabrication, and polymer applications. Research and development activities on functional polymers, polymer blends and alloys, composites and nanocomposites, paints and surface coatings, rubbers and elastomeric materials, and adhesives are also published.
