Abstract
A method for forming a membrane upon an electrode from a dispersed, perfluorocarbon copolymer. Perfluorocarbon is dispersed in a solvating medium, a substantial portion, but not necessarily all of the perfluorocarbon being solvated. The dispersion is applied to an electrode and the dispersion medium is removed.
