Novel electrode structure for DMFC operated with liquid methanol

Novel electrode structures for the direct methanol fuel cell (DMFC) based on Ti mesh are reported. A new anode with a hydrophilic structure prepared by coating Pt-Ru catalyst on Ti mesh using thermal decomposition showed a performance comparable to that of the conventional porous carbon-based structure one in DMFC, whilst a cathode with the same structure showed a poor performance. When a porous structure based on Ti mesh pre-coated with carbon was used as the cathode structure, the performance increased significantly to reach that of conventional carbon paper-based cathode.
