Fabrication and performance test of Membrane Electrode Assembly (MEA) by using Pd-Co/C catalyst on Proton Exchange Membrane Fuel Cell (PEMFC) had been done. Mass ratio Pd-Co/C catalyst was varied by using impregnation method. Furthermore, electrode sized 25 cm2 with loading 0.5 mg/cm2. Anode side was sprayed with Pd:Co catalyst varied by mass ratio at 1:0; 0.75:0.25; 0.50:0.50; 0.25:0.75; 0:1, …
