摘要:
The invention relates to method for connecting an electrically conductive contact element (1) to at least one electrically conductive fuel cell component (2) which is associated with a fuel cell (4). Said method comprises the following steps: a contact element (1) which is soluable in a solvent (5), and an electrically conductive fuel cell component (2) are provided; a solvent (5) is applied to the contact element (1) and/or to the fuel cell component (2); the contact element (1) is arranged on the fuel cell component (2); the solvent (5) is evaporated for forming a contact between the contact element (1) and the fuel cell component (2).
摘要:
The invention relates to a series circuit arrangement of power semiconductors (4), having a cooling water distribution device (2), comprising cooling water cans (6) which are arranged on the power semiconductors (4) and are electrically conductively connected to the power semiconductors (4), and at least two cooling water distribution lines (8, 9), a first cooling water distribution line (8) having a cooling water feed (18) and a second cooling water distribution line having a cooling water discharge (20), and the cooling cans (6) being connected in parallel between the cooling water distribution lines (8, 9) relative to a cooling water flow (10) and, for the cooling cans (6), a branch (12) respectively being provided on the cooling water distribution lines (8, 9), and the cooling cans (6) being connected to the branches (12) via a connecting line (14) each, a control electrode (16) also being arranged on each of the cooling water distribution lines (8, 9), at the ends, characterized in that, for at least some of the cooling cans (6), the branches on the cooling water distribution lines (8, 9) are arranged relative to the position of the respective cooling can (6) to be offset relative to a geometrically shortest possible attachment (22) to the cooling water distribution lines (8, 9), souch that a potential difference (AU) between the cooling cans and the branches is minimized.
