It is well known that anode and cathode pressures and cell temperature are the effective parameters in performance of Direct Methanol Fuel Cell (DMFC). In the present study, the genetic algorithm as one of the most powerful optimization tools is applied to determine operating conditions which result in the maximum power density of a DMFC. A quasi-two-dimensional, isothermal model is presented to determine maximum power of a DMFC. For validation of this model, the results of the model are compared to experimental results and shown to be in good agreement with them.

. In order to obtain suitable titanium mesh MEA (membrane electrode assembly) for direct methanol fuel cell (DMFC) molding temperature conditions, titanium mesh was used as electrode substrate material, Nafion 117 membrane was used as proton exchange membrane, PtRu/XC-72R and Pt/XC-72R were used as anode catalyst and cathode catalyst respectively, anode and cathode of titanium mesh MEA were prepared by drop-coating method. When the MEAs were molded by hot-pressing under 5 MPa for 180 s with different temperatures of 115°C, 135°C and 155°C, respectively, the maximum power density of Ti mesh-based MEAs increases firstly, after the first peak, it gradually decreases along with the increase of molding pressure conditions, and the maximum power density appears at the molding temperature of 135°C, so conclude that molding temperature of 135°C is more appropriate for making the titanium mesh MEA.
