Abstract
Direct methanol fuel cells (DMFCs) are energy converters and have key features such as high energy density, simple construction, low operating temperature and easy storage of methanol fuel and hence these are considered as potential candidates for portable applications. This chapter provides an overview on recent developments in the DMFC technology. Developments on DMFC components including membrane, catalyst layer, diffusion layer, bipolar plate and current collector are summarized. This chapter also addresses the various technological issues hindering the DMFC commercialization viz. methanol crossover, water crossover, cathode water flooding, carbon dioxide evacuation, poor anode kinetics and degradation.
