Preparation of Cu2O/C and Pt/C catalyst supported on substrate in the form of carbon sheets from gelam bark and carbon vulcan doped with polyaniline using by membrane electrode assembly (MEA) in the direct methanol fuel cell. Carbon sheets and carbon vulcan were mixed with Cu2O/C and Pt/C catalyst inks, polyaniline, PTFE and nafion, then sprayed onto surface of the gas diffusion layer (GDL) to …
