It presents the acquired knowledge of electrooxidation of alcohols (methanol, ethanol, ethylene glycol, and glycerol) in both acid and alkaline media, and state-of-the-art anode catalysts. The chapter reviews the recently developed catalyst preparation methods and novel carbon support materials. High-performance practical electrocatalysts are essential to enhancing electrooxidation of alcohols for DAFCs. In order to improve the catalyst utilization and reactant mass transport, some research efforts have been made to develop techniques that enable to directly grow carbon nanotubes (CNTs) onto gas diffusion layer to obtain ordered electrode structures. Development of novel polymers for high-performance anion exchange membranes should be regarded as of same important research priority as the electrocatalysts for next-generation low-temperature low/zero liquid base alcohol fuel cells.
