ELECTROCHEMICAL CELL HAVING A CURRENT DISTRIBUTOR COMPRISING A CONDUCTIVE POLYMER COMPOSITE MATERIAL
The invention relates to an electrochemical cell which has an electrode (12, 20), a membrane (18) disposed in contact with one side of the electrode and a current bus (46, 48) disposed on the other side of the electrode. A current distributor (40, 42) which is disposed between the electrode and the...

| description | The invention relates to an electrochemical cell which has an electrode (12, 20), a membrane (18) disposed in contact with one side of the electrode and a current bus (46, 48) disposed on the other side of the electrode. A current distributor (40, 42) which is disposed between the electrode and the current bus distributes current to the electrode by electronic conduction. The current distributor is made of a non-porous layer of a conductive polymer composite material. The current distributor thus provides a barrier between the current bus and the reactant and the product of the cell. This is especially important in aggressive environments, such as hydrogen chloride. Thus, the cell of the present invention is particularly useful in converting anhydrous hydrogen halide directly to essentially dry halogen gas, such as anhydrous hydrogen chloride to chlorine gas, or in converting aqueous hydrogen chloride to wet chlorine gas.
L'invention porte sur un élément électrochimique comportant: une électrode, (12, 20); une membrane (18) en contact avec l'un des côtés de l'électrode et un bus de courant (46, 48) disposé de l'autre côté de l'électrode. Un répartiteur de courant (40, 42) placé entre l'électrode et le bus alimente l'électrode en courant par conduction électronique. Le répartiteur de courant, fait d'une couche non poreuse de matériau polymère composite, constitue ainsi une barrière entre le bus, le réactif et le produit de l'élément, ce qui est très important dans un milieu agressif tel que le chlorure d'hydrogène. L'élément objet de l'invention s'avère donc particulièrement utile pour la conversion directe d'un halogénure d'hydrogène anhydride directement en halogène gazeux sec, telle le chlorure anhydride d'hydrogène en chlore gazeux ou le chlorure d'hydrogène en solution aqueuse, en chlore gazeux humide. |
