Abstract
An electrochemical measuring cell is disclosed wherein the diffusion membrane which separates the electrolyte from the ambient is made of an intrinsically-conductive and electrochemically active plastic. This way the diffusion membrane itself defines the measuring electrode of the measuring cell. This is a substantial advantage over known electrochemical measuring cells wherein the measuring electrode is defined by an electrically conductive layer applied to the surface of the diffusion membrane facing toward the electrolyte. By making the diffusion membrane from an electrochemically active plastic, a removal of the electrically-conductive layer from the diffusion membrane is prevented.
