Patent number: 6352742Abstract: A method for producing a polymer electrolyte membrane is disclosed. A liquid medium is introduced into a cylinder having an inner surface having a cylindrical configuration. The liquid medium has at least one percent by weight of a polymer electrolyte and a solvent having a boiling point or an azeotropic point ranging from 60 to 220° C. Subsequently, the cylinder is rotated for evaporating the solvent by means of a centrifugal force created by such rotation so as to form a polymer electrolyte membrane having a cylindrical configuration with a substantially uniform thickness on the inner surface of the cylinder. Onto the inner surface of the polymer electrolyte membrane, a catalytic layer containing a catalytic particle may be formed.Type: GrantFiled: December 20, 1999Date of Patent: March 5, 2002Assignee: Celanese Ventures GmbHInventors: Makoto Murata, Tetsu Yamamoto, Gregor Deckers
