The Effect of 2-Propanol Solvent Volume in Electrodes Making Using the Doctor Blade Method on the Performance of the Membrane Electrode Assembly (MEA) in Direct Ethanol Fuel Cell (DEFC) Mohd Hilal Assegaf: Supervised by Dr. Dedi Rohendi, M.T and Fahma Riyanti, M.Si Chemistry, Faculty of Mathematics and Natural Sciences, Sriwijaya University xi + 61 pages, 4 tables, 8 pictures, 4 appendices Study of the Effect of 2-Propanol Solvent Volume in Electrodes Making Using the Doctor Blade Method on the Performance of the Membrane Electrode Assembly (MEA) on Direct Ethanol Fuel Cell (DEFC) has been carried out. The 2-propanol solvent with various volumes was used in the manufacture of electrodes with a catalyst of Pt / C 40% and Pt-Ru / C 40% using the Doctor Blade method. The electrodes made were characterized using the Cyclic Voltammetry (CV) method to determine the catalytic activity of the electrodes based on the Electrochemical Surface Area (ECSA) value and the Electrochemical Impedance Spectroscopy (EIS) method to determine the value of its electrical conductivity. The Membrane Electrode Assembly (MEA) is made from a combination of two electrodes with an electrolytic membrane. The performance of MEA was tested in Direct Ethanol Fuel Cell (DEFC) using ethanol fuel with various concentrations. Based on the characterization results, it was found that the Pt-Ru/C electrode with a solvent volume of 2-propanol 0.3 mL had the largest ECSA value with a value of 97.753 cm2/g. Meanwhile, the best value of the Pt-Ru/C electrode conductivity was obtained on the electrode made with a solvent volume of 1.2 mL of 3.571 x 10-3 S/cm. The MEA performance test showed the best OCV value occurred in MEA with a solvent volume of 1.2 mL and was able to maintain the stress with the addition of load and produced the highest power density of 3.953 mW/cm2. Testing of MEA on ethanol concentrations varies between 5%-25% v/v showing the best performance of MEA occurs using ethanol fuel at 15% v/v with the highest power density of 3.953 mW/cm2 at a current density of 7.375 mA/cm2.
