VERFAHREN ZUR HERSTELLUNG VON MEMBRAN- ELEKTRODENEINHEITEN (ME) FÜR POLYMER-ELEKTROLYT- MEMBRAN (PEM)-BRENNSTOFFZELLEN

摘要

The invention concerns a method wherein membrane electrode units for fuel cells are produced in a continuous and automatable process. A web of polymer membrane is initially drawn through a bath containing a salt solution of the electrode material so that the web has a salt crust or film on both sides, and the salt adhering is then reduced in a stream of gas or in another bath.
