Abstract

An electrochemical energy converter according to the invention has a plurality of electrodes and at least one outgoing electrical conductor (1, 2), which extends substantially in a longitudinal direction and which therefore has a direction of longitudinal extent (LR), and which is electrically conductively connected to a plurality of these electrodes. A plurality of joints, in particular welded joints (4, 5, 6, 7), is arranged at or on this outgoing electrical conductor in the direction of longitudinal extent at a distance from one another. The outgoing electrical conductor has first cross-sectional areas (QF1) arranged perpendicular to this direction of longitudinal extent at these joints. The outgoing electrical conductor has second cross-sectional areas (QF2) between these joints in the direction of longitudinal extent. These first cross-sectional areas (QF1) are greater and in particular considerably greater than these second cross-sectional areas (QF2), at least in the case of a number of joints arranged adjacent to one another.
