Abstract
A method for preparing an anion exchange membrane suitable for use in an alkaline fuel cell and particularly in a direct borohydride fuel cell, involves radiation grafting a hydrocarbon polymer film with a monomer and adding a quaternising agent. The degree of grafting is improved by mixing the monomer with a diluent comprising alcohol and a hydrocarbon solvent.
Claims20
A method for preparing an anion exchange membrane comprising the steps of:
- selecting a hydrocarbon polymer film;
- radiation grafting the hydrocarbon polymer film with a monomer and adding a quaternising agent to impart ionic conductivity, wherein the monomer is presented in the form of a monomer/diluent mixture and wherein the diluent comprises alcohol and a hydrocarbon solvent.
