Fuel cells based on the anodic exchange membranes (AEMFC) can operate on a variety of fuels and generate high power densities at moderate operating temperatures. The real advantage of AEMFC use in polymer-electrolyte membrane fuel cells is the absence of expensive noble metal catalysts in the electrodes. However, the AEMFC systems have their own set of challenges, as related to materials and processing schemes, which require innovative engineering solutions. Key among these are the conductivity and durability of the anion-exchange membrane, the identification of suitable OH- ion conductive polymers for anode and cathode binders, and the identification/optimization of membrane-electrode-assembly preparation methods. Progress is being made, research funding for AEMFC is seeing an upward trend, and more papers on the subject are being published. The very positive developments over the past ten years resulting in improved PEMFC performance and durability with lower manufacturing costs bode well for similar progress on the AEMFC front, especially given the increasing commitment to this technology that is emerging.
