The preparation of carbon from binchotan to be catalyst ink with manganese metal oxide and its performance test in direct Methanol Fuel Cell has been done. The preparation of MnO2/C catalyst was done by impregnation method. Carbon dots and carbon vulcan were used as supporting carbon with the ratio 40:60 and 60:40 toward MnO2. MnO2 catalyst, nafion and polytetrafluoroethylene (PTFE) were mixed …
