Direct Methanol Fuel Cells

open access: yesPlatinum 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 ...

Numerical investigation of methanol crossover through the membrane in a direct methanol fuel cell [PDF]

open access: yesHydrogen, Fuel Cell & Energy Storage, 2018
A two-dimensional, single-phase, isothermal model has been developed for a direct methanol fuel cell (DMFC). The model considers the anode and cathode electrochemical equations, continuity, momentum and species transport in the entire fuel cell.

Direct Methanol Fuel Cells

open access: yesPlatinum Metals Review, 1996
The direct methanol fuel cell (DMFC) has been considered as the ideal fuel cell system since it produces electric power by the direct conversion of the methanol fuel at the fuel cell anode. This is more attractive than the conventional hydrogen fuelled cells, particularly for transportation applications, which rely on bulky and often unresponsive ...
