Description

Elektrode für elektrolytische Zellen, insbesondere zur Wasserzersetzung. Zusatz zum Patent 411528. In der Patentschrift 411528 ist eine ganz oder zum Teil aus schwefelhaltigem Material bestehende Kathode für elektrolytische Zellen, insbesondere zur Wasserzersetzung, beschrieben, deren Wirksamkeit im wesentlichen darauf beruht, daß ihre Oberfläche Schwefel enthält.Electrode for electrolytic cells, in particular for the decomposition of water. Addendum to patent 411528. In patent specification 411528 is a whole or in part Cathode consisting of sulfur-containing material for electrolytic cells, in particular for water decomposition, whose effectiveness is essentially based on that their surface contains sulfur.

Es wurde nun gefunden, daß die Wirksamkeit derartiger Elektroden auch dann noch bestehen bleibt oder sich sogar noch verbessert, wenn der Schwefel zum mindesten aus der Oberfläche vorsichtig wieder entfernt wird, wie dies z. B. beim Gebrauch der Elektrode allmählich von selbst geschieht.It has now been found that the effectiveness of such electrodes also then still persists or even improves when the sulfur is added is at least carefully removed from the surface, as z. B. at Use of the electrode will gradually happen by itself.

Weiterhin wurde gefunden, daß sowohl die geschilderten schwefelhaltigen als auch die Elektroden, an deren Oberfläche der Schwefel in schonender Weise wieder entfernt ist, auch bei der Verwendung als Anoden Vorteile bieten, indem hier die Spannung ebenfalls niedriger ist als an dem gleichen Metall ohne Schwefel bzw. ohne Behandlung mit Schwefel.It was also found that both the sulfur-containing as well as the electrodes, on the surface of which the sulfur is gently restored is removed, even when used as anodes offer advantages here by the Voltage is also lower than on the same metal without sulfur or without Treatment with sulfur.
