Development and testing of an anion exchange membrane electrolyser

In the context of energy policy and the use of renewable energies, our research institute collaborates with other partners on the development of a compact, environmental-friendly and effective electrolyser for efficient power storage. This electrolyser combines the positive properties of the alkaline water electrolysis and the proton exchange membrane (PEM) electrolysis. On the cathode side on porous current collectors were electrodeposited in one step multi-component non-precious alloys. New cross-linked anion-exchange membranes have been developed to achieve high ionic conductivity. The anode side was coated with the sol-gel method. The catalytic activity of the electrodes was investigated by electrochemical studies. Current collectors have been tested under real conditions of electrolysis. For the construction of a corresponding single cell, media supply was taken into consideration and appropriate materials for current collectors, the bipolar plates and gaskets were selected.
