Abstract

A membrane-electrode structure for use in an electrochemical cell comprising an ion exchange membrane with a cathode layer and an intermediate layer between the cathode and the membrane. The intermediate layer comprises 5 to 80 percent by weight of inorganic solid particles and 95 to 20 percent by weight of an ionic conductive polymeric binder.
