ABSTRACT:
A membrane-electrode structure for use in an electrochemical cell comprising an ion exchange membrane with a cathode layer and several intermediate layers between the cathode and the membrane. The intermediate layers comprises at least two layers or zones of inorganic solid particles and an organic polymer binder. The intermediate layer or zone adjacent to the membrane comprises more than 50% by weight of inorganic particles and the other layers or zones have 50% by weight or less of inorganic particles.
