Highly stable self-crosslinked anion conductive ionomers for fuel cell applications†
Abstract
We report a simple method for the preparation of self-crosslinked anion conductive ionomers (SCL-ACIs) via polycondensation–Friedel–Crafts alkylation reactions without using any catalyst or crosslinking agent. The reported alkaline stable and methanol impervious SCL-ACIs with 2.45 mequiv. g−1 ion-exchange capacity (IEC) and 68 mS cm−1 hydroxide ion conductivity were assessed as suitable candidates for alkaline direct methanol fuel cell (ADMFC) applications.
