In galvanic cells and polarographic electrodes, the {{c1::electrical current}} is proportional to the O2 concentration.

How are galvanic cells used to measure oxygen flow?
Galvanic cell (fuel cell) contains a lead anode and gold cathode bathed in potassium chloride. At the gold terminal, hydroxyl ions are formed that react with the lead electrode (thereby gradually consuming it) to produce lead oxide, causing current, which is proportional to the amount of oxygen being measured, to flow.
The lead anode is gradually consumed.
Galvanic cells do need to be calibrated every day.
