Method and characterisation In this research, the electrochemical impedance spectroscopy (EIS) test was conducted to the standard MEA, mordenite modified binding layer MEA, sulfonated mordenite modified binding layer MEA, and graphene oxide modified binding layer MEA. The test was made at different fuel cell temperature (40°C-70°C), at different methanol concentration (1.0 M, 2.0 M, and 4.0 M), and at different material (mordenite /graphene oxide) weight percentage per loading. These results are presented in the next chapter (result chapter) for each modified binding layer type. Before, the EIS test, each prepared MEA placed in DMFC goes under conditioning mode and a polarization curve (cell voltage vs current density) plot is made to assign the ohmic loss region and thus use this value in the EIS software to conduct the AC impedance test. It was found in this research that ohmic region loss was between 0.35V-0.45Vt. Therefore, the EIS test was conducted using potentiostatic mode at 0.4V. 3.2.7 Evaluation of Methanol Crossover (Permeability) In DMFC When the methanol (anode fuel feed) passes from anode to cathode without utilizing the fuel at the anode, crossover takes place. This cause a mixed potential at the cathode thus drops the fuel cell efficiency. Figure 3.11 Fuel crossover example in DMFC Since this research is concerned with reducing the methanol crossover in DMFC, evaluating the methanol crossover for each MEA was needed. The crossover is Sirhan AL-Batty Page 88PDF Image | Membrane Electrode Assembly Modification by Zeolite and Graphene Oxide
