Device for the production of hydrogen

This invention relates to a device for the electrolytic production of hydrogen and oxygen from a water-containing liquid, the device comprising: an anodic half-cell (3) and a cathodic half-cell (4), with an anion exchange membrane (9) situated between the two half-cells. The electrodes (7, 8) of the...

Beschreibung
Zusammenfassung:	This invention relates to a device for the electrolytic production of hydrogen and oxygen from a water-containing liquid, the device comprising: an anodic half-cell (3) and a cathodic half-cell (4), with an anion exchange membrane (9) situated between the two half-cells. The electrodes (7, 8) of the half-cells (3, 4) and the anion exchange membrane (9) form a membrane/electrode assembly (MEA). There is also provided means (2) for feeding the water-containing liquid to only one of the anodic half-cell (3) and the cathodic half-cell (4), wherein the electrode in the other, substantially dry, half-cell is ionomer-free and/or binder-free.
