Abstract

The cell is filled with an electrolyte but partitioned into two chambers, one of which contains a particular additive which will react with a component of a fluid, e.g. air; no such reaction occurs in the other chamber. The two electrodes are similarly configured and both permit contact between the fluid and the electrolyte so that any other electrochemical reactions occur to a similar degree on both electrodes.
