Abstract

A process for manufacturing an electrochemical transducer, having at least one active element in the form of at least one film of a polymer material, comprises the following steps. First, clamping a polymer film between an inner set of jaws for delimitating a central area. Second, further clamping said polymer film between an outer set of jaws for delimitating a peripheral area surrounding the central area. And finally, shaping at least one of the areas by stretching.
