  • Membrane electrochemical cell provided with gas diffusion electrodes in contact with porour, flat, metal current conductors having highly distributed contact area
    Patent number: 6022634
    Abstract: The present invention refers to an electrochemical cell or stack of cells comprising two end-plates (7), bipolar plates (1) made of metal or metal alloy, gas permeable metal distributors (2), metal current collectors(3), gasket frames (4) provided with channels for feeding the gaseous reactants and discharging the excess reactants and condensates, a couple of gas diffusion electrodes, (5), an ion-exchange membrane (6), wherein said current conductors provide for a highly distributed segmented contact area on the electrode surface without isolated peaks and have an extremely smooth surface without asperities and at the same time porous and permeable to the gas flow.
