Electric connector for fuel cell stack

A method for fastening an electrical connector assembly to a fuel cell stack arrangement with at least one fuel cell unit comprising at least one bipolar plate and at least one membrane electrode assembly, wherein the electric connector assembly comprises at least a support structure and at least one contact pin, which is adapted to electrically contacting the bipolar plate and is supported by the support structure, wherein the support structure comprises at least a rear face which is adapted to face the fuel cell stack, a front face being opposite to the rear face, and first and second side faces, wherein the rear face comprises at least one bipolar plate housing slit which extends from the first side face to the second side face, and which is adapted to accommodate at least partly the bipolar plate, thereby defining a comb-shaped support structure with at least two teeth extend from a support basis, which are separated by the intermediately arranged bipolar plate housing slit, and wherein the support structure further comprises at least one contact pin accommodation opening having a size which is adapted to accommodate the contact pin, the method comprising the following steps:

• arranging in each bipolar plate housing slit of the support structure at least partly a single bipolar plate;
• and
• pressing a contact pin into each contact pin accommodation openings, so that the contact pin protrudes into the slit and contacts the bipolar plate, thereby deforming the bipolar plate and fastening the bipolar plate in the bipolar plate housing slit and to the support structure.
