A sensor cell () for control purposes usable in an assembly () of fuel cells of the type having a membrane electrode assembly (MEA) interposed between an anode gas diffusion layer and a cathode gas diffusion layer, and first and second current collectors coupled to the anode and cathode gas diffusion layers (GDL), respectively. The sensor cell () is preferably coupled so that it shares the negative current collector () with last fuel cell in the in-plane fuel cell assembly (), and is short-circuited by a resistor () to provide a voltage signal, indicative of the status of the assembly in operation.

Fuel cell assembly having feed-back sensor

An arrangement for interconnecting electrochemical cells of the type having a membrane electrode assembly (MEA) interposed between an anode gas diffusion layer () and a cathode gas diffusion layer (), 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 () which is in contact with the anode gas diffusion layer (GDL;) of a first electrochemical cell () is configured to be connected to the cathode side of a second, adjacent electrochemical cell () via an inert and electrically conductive member (), without being in electrochemical contact with the electrochemically active components of the adjacent cell.
