摘要：

Anion-exchange membranes (AEMs) are of growing interest for electrochemical devices such as fuel cells and electrolyzers because the alkaline medium allows avoiding the use of platinum and platinum-group metals as the electrocatalysts. Perfluorinated polymers are a good starting point to prepare AEMs because of their chemical stability and potential high conductivity resulting from the coexistence of hydrophobic main chains and flexible hydrophilic side chains. Here, we report a facile and simple chemical modification of Aquivion (R) performed in aqueous environment. We obtained a chemically stable membrane with ionic conductivity exceeding 2.5x10(-2) S cm(-1) at 80 degrees C and 100 RH% that was used in a polymer fuel cell.
