Wasewar Journal on Future Engineering and Technology 2230 – 7184 7 4 44 49 Direct Methanol Fuel Cell, Passive, Mathematical Model, Analytical Analysis The passive DMFC is a multiphase system involving simultaneous mass, charge and energy transfer. To make this complex system simpler a one-dimensional, steady state, isothermal model has been developed. This model considers mass transfer effects along with the electrochemical reaction. The model was validated with available experimental data. The model result for polarization curve was found in excellent agreement with the available experimental data. The model can be used for improving DMFC understanding and optimize fuel cell design. Even if presented model contains several simplified assumptions, it efficiently describes mass transfer phenomena in a passive DMFC, when different operating parameters are varied on large scale.
