METHOD FOR DETERMINING MATERIALS CONVERSION IN ELECTROCHEMICAL REACTIONS AND ELECTROCHEMICAL UNIT

摘要

The invention relates to a method for determining materials conversion in electrochemical surface reactions in at least one local surface area between a surface counter-electrode device (20) and a surface electrode device (30) which has a contact element section (34s) matching the surface area and a contact element (34) in contact with the other surface areas. In order to improve said method so that materials conversion to be determined as easily as possible, the contact element and the contact element section are connected to a power source or to a current sink (90) which are provided for the operation of the electrochemical reaction. A current flowing through a conductor (44) arranged between the contact element section and the power source or current sink generates a magnetic field (70) around said conductor and the magnetic field is used to measure materials conversion in the local surface area.
