Abstract
An electrochemical device includes an anode, a cathode, and a separator interposed between the anode and cathode. The separator includes an anion conductive membrane having a porous substrate having hydrophilic moieties bonded thereto to increase water availability in a vicinity of ionogenic sites contributing to conductivity of the membrane in a presence of aqueous phases imbibed therein.

An electrochemical device comprising:
- an anode;
- a cathode;
- and
- a separator interposed between the anode and cathode comprising an anion conductive membrane including a porous cross-linked polymeric substrate having non-ionic hydrophilic moieties bonded thereto to increase water availability in a vicinity of ionogenic sites contributing to conductivity of the membrane in a presence of aqueous phases imbibed therein, the hydrophilic moieties being functionalized with cations that are chemically modified to hinder degradation by substitution or elimination reactions.
