Silver-Electrodes for Chlorine-Alkali Elektrolysis

Uhde GmbH (1998 - 2004)

In 1998 we started cooperating with Krupp-Uhde GmbH (now Uhde GmbH) in the field of chlorine-alkali electrolysis by using gas diffusion electrodes as cathodes.

We could provide Uhde with modified Slilflon-electrodes (originally developed by Hoechst AG) as well as with our own development - the Oxag Electrode. These electrodes were tested for weeks in Bitterfeld and Gersthofen (both in Germany) in electrolysis cells with an active area of 0.16 m².

With 4 kA/m² we achieved a stable cell voltage of 2.2 V. After this promising result we started tests with wider electrodes in order to apply them in cells with a bigger active area.

Because of this good and innovative cooperation we will equip a pilot plant with these electrodes in the near future.
