Preferred Label : auxiliary electrode;
IUPAC definition : Three-electrode cells comprise (1) an indicator (or test) electrode or a working electrode,
at the surface of which processes that are of interest may occur, (2) a reference
electrode and (3) a third electrode, the auxiliary or counter electrode, which serves
merely to carry the current flowing through the cell, and at the surface of which
no processes of interest occur. If processes of interest occur at both the anode and
the cathode of a cell (as in differential amperometry or controlled current potentiometric
titration with two indicator electrodes), the cell should be said to comprise two
indicator (or test) working electrodes.;
