According to the invention, the metal part of the interconnector comprises two interspaced flat metal sheets (90, 91) and at least one element forming a pierced connector (92, 93), the at least one connector being arranged so as to lie against the two flat metal sheets without obstructing the apparent holes (820), thereby defining the chamber (81) adjacent to the plane PI of the electrode, the two metal sheets and the at least one connector being welded to each other at least around portions of each hole (820) of a group of holes. |
