Abstract

A membrane electrode assembly comprises a membrane, a catalyst and an electrode, in which the membrane is obtainable by the steps of (i) forming a polymer film and (ii) reacting the film with a material having strongly ionic groups, to form a polymer film having the ionic groups grafted thereon.
