POLYMER COMPOSITE IONIC/ELECTRONIC CONDUCTANCE MEMBRANE METHODS FOR THE PRODUCTION THEREOF AND A PLANAR FUEL CELL CORE COMPRISING SAID MEMBRANE

摘要

The invention relates to an ion/electron-conducting composite polymer membrane (10′), which comprises at least two gas-tight ion-conducting polymer portions (11′) joined together directly by a gas-tight electron-conducting polymer portion (12′). It also relates to processes that enable this membrane to be manufactured, and also to a planar fuel cell core comprising it. Applications: production of planar fuel cells used for generating electrical power intended for stationary applications, transport applications and portable and transportable applications.
