Contact arrangement for fuel cell stack electrodes has contacts of different electrical polarities spaced at surround perpendicular to stack direction

摘要

A contact arrangement for fuel cell stack (1) electrodes having a membrane between anode and cathode plates and/or bipolar plates (13,14,15) and with at least one contact (16,18) to apply a voltage to these at the stack surround (19) comprises elements having different polarities spaced at the surround perpendicular to the stack direction (11).
