1. A voltage-measuring device configured to carry out voltage measurements on a laminate assembly formed of separators and of at least one membrane electrode assembly stacked along a direction of lamination to form an electrochemical cell or a plurality of superimposed electrochemical cells,
one of the separators being located at each end of the laminate assembly, the voltage-measuring device comprising two measuring plates, each of the two measuring plates having a measuring face on which are distributed a plurality of spaced-apart electrical contacts electrically insulated from each other, wherein
the plurality of spaced-apart electrical contacts of each of the two measuring plates are distributed over the measuring face such that each of the electrical contacts of one of the measuring plates is aligned with an associated respective said electrical contact of the other of the measuring plates when the measuring faces of the measuring plates are arranged opposite each other; and
the measuring plates being configured to be arranged on opposite sides of the laminate assembly, the measuring face of each said measuring plate being applied against a respective said separator of the two separators located at the ends of the laminate assembly, such that the electrical contacts on that measuring face (24A) are in contact with said separator.
