ABSTRACT OF THE DISCLOSURE A membrane for an electrochemical cell, inhibiting the diffusion of gases and allowing ionic conduction. The mem- brane comprises from about 2.5 to about 30 weight percent of an organic binding agent and from about 97.5 to about 70 weight percent of polyantimonic acid powder, the grain size of the polyantimonic acid powder being less than 38 µm. The membrane is selectively permeable to cations in a basic medium and is selectively permeable to anions in an acidic medium. The membrane overcomes disadvantages of prior art membranes. An electrochemical cell comprising the membrane is also disclosed.
