Electrode arrangement and procedures for electrochemical hydrogen peroxide production and biotransformation

摘要

The invention concerns an electrode device for the electrochemical production of hydrogen peroxide (H2O2). The electrode device includes the following:(a) a first end and a second end having a first electrode;(b) a second electrode with a first end and a second end;(c) an electrode housing consisting of non-conductive material containing the first electrode and the second electrode at the first ends; and(d) an internal electrode chamber enclosing the first electrode in a first electrode range for the reception of an aqueous electrolyte, where:and. at least part of the wall of the internal electrode chamber is formed by the second electrode,Hey. the internal electrode chamber has an opening for the supply of the aqueous electrolyte,iii. the second electrode is a porous body permeable by the aqueous electrolyte at or above a pressure p in the electrode chamber or includes a porous body permeable by or above a pressure p in the electrode chamber;iv. the internal electrode chamber is formed at least up to pressure p.
