Electrochemical Thin Layer Cells
Thin layer cells are widely used in electrochemistry. The two flat working electrodes (red plates in the left figure) are separated by a thin space of width . This Demonstration shows the configuration (on the left) and chronoamperometric measurement (on the right) for such a thin layer cell.
Snapshots 1 and 2: for a given distance , the reactant in solution is consumed with time; its color is lighter
Snapshots 3 and 4: when the distance is small, the reactant in solution is consumed more rapidly and the current reaches a steady-state value earlier
