Simultaneous Impedance measurements on each element

Electrochemical generators such as primary and secondary batteries, fuel cells(FCs) and supercapacities are often made up of several elements connected in series. It is possible to connect dozens of these elements on FC stacks. The measure of the potential difference on each cell allows the user to detect if there is a dysfunction on a cell but does not give the reason why. On the other hand, impedance measurements on the different cells under a constant load, can be useful, for example, to determine the internal resistance value or if there is a problem with the gas distribution in the stack.
