Crosslinked poly (ether ether ketone) (PEEK) hydroxide exchange membranes are prepared using bi-functional cyclic ammonium, 1,4-diazabicyclo [2,2,2] octane (DABCO), as simultaneous quaternization and crosslinking reagent. Hydroxide conductivity and ion mobility are evaluated as a function of ion con...
