Abstract
A system for monitoring the viability of an electrochemical cell measures the impedance of the cell over a wide range of impedances and with diminished phase shift over prior methods so that a more nearly accurate assessment of the impedance can be made. The system is particularly useful for four electrode systems, but is not so limited. It may advantageously be incorporated in the cell itself to further minimize cabling artifacts.
