Voltage measuring device for measuring the voltage of a plurality of electrochemical cells of an electrochemical reactor

A voltage measuring device configured to measure a voltage of a plurality of electrochemical cells of an electrochemical reactor formed of a stack of separators and membrane-electrode assemblies, each of the electrochemical cells being formed of one of the membrane-electrode assemblies interposed between two of the separators, the voltage measuring device comprising:

• a support comprising:
• a base having an edge;
• a double-contact tooth;
• and
• a plurality of single-contact teeth arranged in a row, each of the single-contact teeth extending from the edge of the base along a common direction of extension, each of the single-contact teeth comprising:
• a proximal end connected to the edge of the base;
• a free distal end;
• and
• only one electrical contact disposed on the free distal end, the electrical contact being configured to make contact with one of the separators;
• wherein the double-contact tooth extends from the edge of the base along the common direction of extension, the double-contact tooth comprising:
• said proximal end connected to the edge of the base;
• said free distal end;
• a first electrical contact disposed on the free distal end;
• and
• an additional electrical contact also disposed on the free distal end,
• wherein each of the single-contact teeth has one of a first length and a second length measured from the edge of the base to the contact, the first length and the second length being unequal,
• wherein the single-contact teeth are arranged on the base so that the single-contact teeth having the first length alternate with the single-contact teeth having the second length,
• wherein the first electrical contact and the additional electrical contact of the double-contact tooth are both arranged at either the first length or the second length from the edge of the base, and
• wherein the double-contact tooth is arranged on the edge of the base at one end of the row of the single-contact teeth.
