Abstract The research then was about performance and durability tests on the Membrane Electrode Assembly (MEA) using the catalyst of Pt-Ru/C and Pt/C for Direct Methanol Fuel Cell (DMFC) Mulitstack. Membrane Electrode Asssembly (MEA) was made by combining Pt-Ru/C and Pt/C with nafion membrane 117. MEA were characterized using Cyclic Voltammetry (CV) to determine the site active catalytic and th…
