The test results (figure A) under steady state conditions indicate MEA made by PANI modified anode exhibits better performance thanommercial MEA (from fuel cell store) made by alloyed catalyst and high metal content. Figure B, shows the performance of modified anode in DMFC under different temperatures. As you can find new modified MEA has good stability in different operational conditions. Finally, the test results of the different fuel flow rate in the anode side promotes PANI can act as barrier for methanol crossover from the anode to the cathode side. This conclusion attributed to increasing of catalyst activity of the polyaniline modified anode for methanol oxidation and improvement of electron and proton conductivity of the polyaniline nanofiber modified anode.
