A three-dimensional two-phase non-adiabatic model is proposed for air-breathing micro directmethanol fuel cells (DMFC). The coupled heat and mass transport, along with the electrochemicalreactions occurring in the air-breathing DMFC are modeled. Based on this new non-adiabatic model,the reactants distribution and concentration distribution, the pressure and flow velocity distribution, thesaturation distribution, the potential and current density distribution, the temperature distribution andtheir effects on the cell performance are carefully examined.
