The research about the application of carbon dots from binchotan and SnO2 ink as catalyst layer in Membrane Electrode Assembly (MEA) of Direct Methanol Fuel Cell (DMFC) has been done. Carbon dots was prepared by electrolysis and sonication then ball milled with 40% and 60% SnO2 against carbon dots formed SnO2/C catalyst. Gas diffusion layer (GDL) were made with varied conductive components whic…
