Abstract

An electrochemical cell comprises a housing having an electrochemical circuit system therein including a cathode, an anode and an electrolyte solution in contact with the anode and the cathode. A
conductive diaphragm is arranged in the top portion of the housing for cutting off current flow between the cathode and the anode, and is adapted for quick movement between a first stable conducting position and a second stable non-conducting position upon direct application of gas pressure generated in the electrochemical circuit system in excess of a first predetermined pressure. The conductive diaphragm is unstable between the first and the second stable positions. A conductive lead extends from the electrochemical circuit system to the conductive diaphragm and is connected to same when the conductive diaphragm is arranged in its first stable conducting position. When the conductive diaphragm moves to its second stable non-conducting position, it is separated from the conductive lead and, thus, an open circuit condition is created between the cathode and the anode.
