Abstract
Electrochemical cell (1) acting as a Potential Electrochemical Microscope (PEM), comprising a working electrode (2) and a counter electrode (3), a solid electrolyte (4), at least one sensor (5) of a characteristic quantity of the cell, at least two current collectors, at least one potential collector (6) and a support supporting the working electrode (2), the counter electrode (3), the electrolyte (4), the sensor (5), and the current collectors (6). The device is parallelepiped, cylindrical, spherical, semi-spherical or conical, and it comprises a lower support, an upper support and a seal separating the lower support and the upper support, and the lower support comprises at least five compartments for storing electrochemical cell elements (1).
