Abstract
An electrolysis cell with a fixed-bed electrode and its use for the purification of waste gases. The electrolysis cell includes a fixed-bed electrode, a counterelectrode which is separated from it and designed as a gas diffusion electrode, devices for the supply and flow-off of an electrolyte as well as for the inlet and outlet of the gas to be purified and a space associated with the counterelectrode with devices for the supply and the removal of a gas. In order to purify gas the fixed-bed electrode is operated as a trickle bed and the gas to be purified flows in cocurrent or countercurrent flow to the electrolyte. In reductive purification hydrogen is supplied to the gas diffusion electrode and in oxidative purification oxygen is used.
