In this chapter a new type of solid electrolyte membrane for low-temperature fuel cell application, the anion exchange membrane (AEM), is reviewed. The properties, advantages, and challenges of the anion exchange membranes are discussed.


Anion exchange membranes (AEMs) are used as solid polymer electrolyte in the alkaline membrane fuel cell (AMFC) technology, also referred to as anion exchange membrane fuel cell (AEMFC). In this relatively novel fuel cell technology, the OH is being transported from the cathode to the anode through the anion exchange membrane. In other words, the membrane acts as an anion-conducting membrane between both electrodes of the fuel cell.

The fuel cell reactions for an alkaline membrane fuel cell are described below:
$$ {\mathrm{ H}}_2+{2\mathrm{ O}\mathrm{ H}}^{-}\Rightarrow {2\mathrm{ H}}_2\mathrm{ O}+{2\mathrm{ e}}^{-}\kern1em \mathrm{ anode} $$
