A composite membrane (1) for an electrochemical cell, i.e. a fuel cell or electrolyser system, is described which comprises a mat (2) having a microporous structure of fibrils (3) which consist of expanded polytetrafluoroethylene (ePTFE) and are covered by a film of a polymer (10), especially polyimide or THV, and further comprises an ionomer (5) filling the pores of the microporous structure of the mat and allowing an ion exchange through the membrane. |
