Development of Direct Methanol Fuel Cell and Special Proton Exchange Membranes Impervious to Methanol
[attachment=37839]
Mechanism for Methanol Oxidation
Electrosorption (forming Pt-CH2OH, Pt2-CHOH
species) of methanol onto Platinum layer deposited on MEA
Addition of oxygen to adsorbed carbon containing intermediates generating CO2
Three components of the Fuel Cells
Electrode Material: Special conducting carbon Vulcan XE-72 available with Cabot Corporation, USA.
Anodic Catalyst: Platinum-Ruthenium adsorbed on conducting carbon. Procedure of making it is well documented.
Cathodic Catalyst: Platinum adsorbed on conducting carbon. Procedure of making it is well documented.
Membrane: Nafion Membrane available with DuPont USA. They create lot of problems before supplying.
