Abstract: The voltage-measuring device is adapted to perform voltage measurements on a laminate assembly formed of separators and of at least one membrane electrode assembly stacked to form one or more electrochemical cells. It includes two measuring plates on which are distributed a plurality of electrical contacts spaced apart from each other and electrically insulated from each other, the measuring plates being configured to be arranged on either side of the laminate assembly, the measuring face of each measuring plate being applied against a respective separator in such a way that the electrical contacts located on this measuring face are in contact with the separator.
