Putting a simple electrochemical cell, except for the introduction of the depolarizer. The NaCl solution is placed two electrode potential difference. For a fixed load of the external circuit of the discharge element approximately 10-15%. After discharge element, without opening an external circuit element will cover a glass bulb and increase the percentage of carbon dioxide up to 3% in the composition of air under the bulb - we can fix the charge element Keeping a stable amount of carbon dioxide under the bulb - can maintain the health of the element.
