Abstract: A sensor cell (1010) for control purposes usable in an assembly (1000) 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 (1010) is preferably coupled so that it shares the negative current collector (1050) with last fuel cell in the in-plane fuel cell assembly (1000), and is short-circuited by a resistor (1070) to provide a voltage signal, indicative of the status of the assembly in operation.

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.

Abstract: A process for applying a heat sealable layer to a substrate in which the substrate is provided with a coating composition containing a cyclic imide, which can be a maleimide, an itaconimide, a citraconimide or a 2,3 dialkyl maleimide. Preferably the coating composition is brought on the substrate from a water borne formulation in which the coating composition containing a cyclic imide is dispersed in the water phase and the coating composition containing a cyclic imide is a copolymer of cyclic imides and vinylic co-monomers, preferably a co-polymer of cyclic imides and styrene. The dispersed product in the water phase has a particle size between 20 and 500 nm, preferably between 30 and 200 nm, and the particles have a core-shell structure.
