Abstract
An electrolysis cell for carrying out chemical reactions include an electrolyte chamber (2) with a fixed-bed electrode (2F), a gas chamber (1) filled with filling bodies (1F), a gas diffusion electrode with an ion-exchanging separator (3) applied on the electrolyte-chamber side. The ion-exchanging separator is applied onto the gas diffusion electrode by a method comprising a single or multiple application of a solution of an ion-exchanging material in a solvent onto the electrocatalytically active layer of the gas diffusion electrode and at least partial evaporation of the solvent after each coating. The electrolysis cell may be used for the oxidation and reduction of organic or inorganic components dissolved in the electrolyte.
Claims7
An electrolysis cell for carrying out chemical reactions, comprising:
- an electrolyte chamber filled with electrically conductive filling material for receiving a liquid electrolyte,
- a gas chamber filled with electrically conductive filling material for receiving a gas to be oxidized or reduced,
- a gas diffusion electrode arranged between the gas chamber and the electrolyte chamber, wherein said gas diffusion electrode is connected on the electrolyte chamber side to an ion-exchanging separator,
- current collectors for the gas diffusion electrode and the filling material which act as a counterelectrode in the electrolyte chamber, and
- devices for supplying and removing the electrolyte and the gas,
- wherein the ion-exchanging separator is applied onto the gas diffusion electrode by a method comprising single or multiple applications of a solution of an ion-exchanging material in a solvent onto an electrocatalytically active layer of the gas diffusion electrode and at least partial evaporation of the solvent after each coating.
