Abstract
Described herein are crosslinked alkylated poly(benzimidazole) and poly(imidazole) polymer materials and devices (e.g., fuel cells, water electrolyzers) including these polymer materials. The polymer materials can be prepared in a convenient manner, allowing for applications such as anion exchange membranes (AEMs). The membranes provide high anion conductivities over a wider range of operating conditions when compared to the analogous membranes that are not cross-linked. The crosslinked polymer materials have improved alkaline stability, when compared to the analogous non-crosslinked polymer materials.
