Abstract

The invention concerns a test cell for an EQCM of an electrochemical system comprising a liquid electrolyte. It comprises: - a cell body (10) comprising an electrolyte cavity (11), a quartz resonator (12) coated with a first working electrode (FW) with an active material to be tested and being configured to provide a signal function of a mass variation of the first working electrode (FW), - a cell basis (20) comprising a connecting terminal (22) receiving the signal from the quartz resonator (12), The test cell (8) also comprises a cell holder (30), comprising: - a second electrolyte cavity connecting with the first electrolyte cavity, - a second working electrode, connected to the quartz resonator through the first and second electrolyte cavity (11), comprising similar material to the active material to be tested, - a counter electrode connected to the quartz resonator through the first and second electrolyte cavities (11).
