APPARATUS FOR REDUCING OR OXIDIZING COMPONENTS IN AN AQUEOUS SOLUTION

摘要

1. Device for the reduction or oxidation of reducible or oxidizable substances in an aqueous solution with a feed line for introducing gaseous reducing or oxidizing agents into the solution the opening of which is closed by a fine-pored catalyst layer containing an electrochemically active catalyst which is permeable to the reducing agent or the oxidizing agent, characterized in that the catalyst layer (4) is covered on its side facing towards the solution with a protective body (5) made of electrically conductive material which is permeable both to the reaction gas flowing into the solution and to the solution and is in electrically conductive contact with the catalyst layer.
