Alkaline Direct Methanol Fuel Cell [PDF]
ECS Transactions, 2006 Polymer electrolyte membrane based direct methanol fuel cells (PEM-DMFC) have a complicated system design, and their fuel efficiency is limited by methanol cross-over through the proton exchange membrane. In addition, the methanol oxidation kinetics as well as oxygen reduction kinetics are quite slow in the acid electrolyte system. In contrast
