MEMBRANE WITH INCREASED DURABILITY FROM PARTIAL ION EXCHANGE
摘要
An ion exchange membrane (52) for a fuel cell comprises a polymer having an acid functional group normally including protons, and having alkali metal ions partially ion-exchanged with the protons of the acid functional group of the membrane. The partial ion exchange of alkali metal ions into the membrane relates either to patterning of the exchanged ion make-up of the membrane, with some being ion exchanged and some not, or to the extent or concentration of the ion exchange in any particular location, or to both.
