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

Platinum Metals Review, 1987 Unlike other fuel cell types, the direct methanol fuel cell does not require a separate hydrogen generation system and therefore has greater commercial potential, particularly for powering portable appliances. However, the limiting factor for the cost-effective performance of such systems is the catalytic activity of the electrodes, in particular the ...
