The invention relates to the coating of anion exchange membranes with catalytically active substances. The catalytically actively coated anion exchange membranes are used in electrochemical cells, especially for water electrolysis. The problem addressed by the invention is that of specifying a process for coating an anion exchange membrane which can be conducted at relatively low temperatures. This problem is solved by a swelling step. Aside from the swelling step and the processing temperature, the sequence of the process according to the invention resembles a decal process. However, the use of the partly liquid swelling agent means that the process according to the invention can be considered to be a wet process. The process enables the processing of anion-conducting polymers at moderate temperatures. The anion-conducting polymers may be present in the anion exchange membrane and/or in the composition that is applied to the anion exchange membrane. The advantage of the process according to the invention is that it can be conducted at comparatively low temperatures, namely below 100°C.

Abstract The invention relates to the coating of anion exchange membranes (AEM) with catalytically active substances. The CCM thus obtained are used in electrochemical cells, especially for alkaline water electrolysis. It was an object of the invention to specify a process for producing a CCM by direct 5 coating which maintains the necessary planarity of the AEM and ideally avoids the use of lost films and eschews CMR substances.

The invention relates to the coating of anion exchange membranes with catalytically active substances. The catalytically actively coated anion exchange membranes are used in electrochemical cells, especially for water electrolysis. The problem addressed by the invention is that of specifying a process for coating an anion exchange membrane which can be conducted at relatively low temperatures. This problem is solved by a swelling step. Aside from the swelling step and the processing temperature, the sequence of the process according to the invention resembles a decal process. However, the use of the partly liquid swelling agent means that the process according to the invention can be considered to be a wet process. The process enables the processing of anion-conducting polymers at moderate temperatures. The anion-conducting polymers may be present in the anion exchange membrane and/or in the composition that is applied to the anion exchange membrane. The advantage of the process according to the invention is that it can be conducted at comparatively low temperatures, namely below 100°C.
