Abstract
Alkaline polymer electrolyte fuel cells (APEFCs) using a quaternary ammonium functionalized ethylene-co-tetrafluoroethylene radiation grafted alkaline membrane were tested under fuel cell conditions using five anion exchange ionomers. The effect of ionomer type played a significant influence over the peak power densities achieved, ranging from 41 to 311 mW cm -2. © The Electrochemical Society.
