ABSTRACT:
An electrochemical cell (10) having a structural organization that permits it to operate as either a galvanic or polarographic cell. The structural organization includes an electrolyte reservoir (E) comprised of a solid-like material such as a gel to releasably hold a liquid electrolyte therein. The cathode electrode (K) is defined to be surrounded by a porous material (16) to convey the electrolyte to the cathode electrode (K) to provide the necessary wetting action with the evaporation through the liquid impermeable, gas permeable membrane (M) for the cell (10). The electrolyte reservoir is spaced below the membrane (M) and is solely conveyed by capillary action to the cathode electrode. A venting element (V) is defined for the cell container (11) to prevent internal pressure variations while preventing loss of electrolyte therethrough.
When the cell (10) functions as a polarographic cell the anode electrode (A) is defined with a very large porous area that permits the cell to be used over its life without the need for physically or electrically refurbishing it.
When the cell functions as a galvanic cell the anode electrode (A) is constructed and defined as a lead wool electrode.
