The alkali degradation of LDPE-based radiation-grafted anion-exchange membranes studied using different e methods.

Radiation-grafted anion-exchange membranes (RG-AEM) in alkaline membrane fuel cells (AEMFC) exhibit promising performances (low resistances, high power outputs and reasonably high alkali stabilities). Much research is focused on developing AEMs with enhanced chemical stabilities in the OH-forms at temperatures >60 °C. This study contributes towards this effort by providing a comparison of three different methods of screening alkali stabilities (where different laboratories conducted experiments on exactly the same batches of RG-AEM).
