Membrane electrochemical cell provided with gas diffusion electrodes in contact with porous, flat, metal current conductors having highly distributed contact area |
摘要 |
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 condenses, 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. <IMAGE> |
