Title (EN) OXYGEN-PRODUCING INERT ANODES FOR SOM PROCESS
(FR) ANODES INERTES PRODUISANT DE L'OXYGENE POUR UN PROCESSUS SOM
Abstract:
(EN) An electrolysis system for generating a metal and molecular oxygen includes a container for receiving a metal oxide containing a metallic species to be extracted, a cathode positioned to contact a metal oxide housed within the container; an oxygen-ion-conducting membrane positioned to contact a metal oxide housed within the container; an anode in contact with the oxygen-ion-conducting membrane and spaced apart from a metal oxide housed within the container, said anode selected from the group consisting of liquid metal silver, oxygen stable electronic oxides, oxygen stable cermets, and stabilized zirconia composites with oxygen stable electronic oxides.
(FR) L'invention concerne un système d'électrolyse permettant de générer un métal et de l'oxygène moléculaire. Ce système comprend un contenant destiné à recevoir un oxyde métallique contenant des espèces métalliques devant être extraites, une cathode placée de façon à être en contact avec un oxyde métallique logé dans le contenant, une membrane conductrice d'ion d'oxygène placée de façon à être en contact avec un oxyde métallique logé dans le contenant, une anode en contact avec la membrane conductrice d'ion d'oxygène et espacée d'un oxyde métallique logé dans le contenant, cette anode étant choisie dans le groupe comprenant de l'argent métallique liquide, des oxydes électroniques stables d'oxygène, des cermets stables d'oxygène ainsi que des composites de zircone stabilisés avec des oxydes électroniques stables d'oxygène.
