Proton exchange membrane fuel cells (PEMFC) have been largely investigated due to its possibility to be used commercially as the new generation power source. However, the high cost of PEMFC electrolyte membrane and catalysts as well as some technical issues like high dependency on water and limited temperature endurance (1) made this mission dimmed. Many scientists recently has turned to alkaline fuel cell (AFC) and tried to develop a solid anion exchange membrane (AEM) electrolyte that can be applied in AFC (2, 3, 4). However, the performances of those AFC are still barely satisfactory. Conductivity and mechanical property of AEM are two major challenges that impede the ultimate performances. The best conductivity of current AEM is still one order of magnitude lower than that of Nafion® (5), which exhibits higher ohmic loss in the performance polarization curve. Another issue is the mechanical property.
