ABSTRACT:
In view of operating temperatures above 100.degree. C., a silver oxide/zinc cylindrical cell is provided with a housing cup which is enclosed by a sealing element formed of PTFE, and which incorporates a double-layer separator whose inner layer is formed of a semi-permeable ion exchange membrane and whose outer layer is formed of a flexible ceramic material. The element is protected against extreme overpressure, in excess of 65 bar, by a rupture line in the form of an indentation in the bottom of the cup.
