Abstract
An arrangement for interconnecting electrochemical cells of the type having a membrane electrode assembly (MEA) interposed between an anode gas diffusion layer (208) and a cathode gas diffusion layer (210), and first and second current collectors coupled to said anode and cathode gas diffusion layers (GDL), respectively, wherein the first current collector extends from the anode side of one cell to the cathode side of an adjacent cell, and wherein the cell components are clamped together. The first current collector (206) which is in contact with the anode gas diffusion layer (GDL; 208) of a first electrochemical cell (200a) is configured to be connected to the cathode side of a second, adjacent electrochemical cell (200b) via an inert and electrically conductive member (204b), without being in electrochemical contact with the electrochemically active components of the adjacent cell.
