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 about 5 to 80% by weight of inorganic solid particles and about 95 to 20% by weight of an ionic conductive polymeric binder.
