ELECTROCHEMICAL ZINC-OXYGEN CELL WITH ION EXCHANGE MEMBRANE

摘要

2833 CA The invention relates to an electrochemical zinc-oxygen cell comprising an oxygen electrode containing a porous electrically conductive layer, a zinc electrode, a diffusion of zincate restricting membrane, preferably an ionexchanging membrane, which is joined directly to the oxygen electrode between the porous layer of this electrode and the zinc electrode, and an electrolyte space between the membrane and the zinc electrode containing a liquid basic electrolyte. by preference the membrane is only slightly permeable for the electrolyte. With this cell no poisoning of the electrochemically active material occurs.
