Method for forming a catalytically active layer on a surface of a membrane which is part of an electrode-membrane unit of an electrochemical cell

摘要

In the method for forming a catalytically active layer on a surface of a membrane, which is part of an electrode-membrane unit of an electrochemical cell and which is formed with a metal oxide and / or metal hydroxide in a polymeric matrix, a membrane (6) in a Holder (5) is fixed and the catalytically active layer is formed on a surface by means of a plasma spraying process in which particles of a catalytically active material are used. On the surface of the membrane, which is arranged opposite the surface on which the catalytically active layer is formed, there is liquid cooling with at least one heat sink (2) and/or on the surface on which the catalytically active layer is formed, at least one cooling gas flow is directed.
