Title (EN) ELECTROCHEMICAL CELL HAVING SYMMETRIC INORGANIC ELECTRODES
(FR) CELLULE ELECTROCHIMIQUE POSSEDANT DES ELECTRODES INORGANIQUES SYMETRIQUES
Abstract:
(EN) An electrochemical cell is fabricated by providing two symmetric electrodes (13) and a solid polymer electrolyte (15) disposed therebetween. The symmetric electrodes, anode and cathode, are made from materials such as ruthenium, iridium, cobalt, zinc, bismuth, cadmium, silver, and oxides thereof. The solid polymer electrolyte (15) is in intimate contact with both the anode and cathode, and is made from a polymeric support structure such as polyvinylalcohol, having dispersed therein a proton conducting electrolyte active species.
(FR) Cette invention concerne une cellule électrochimique fabriquée à partir de deux électrodes symétriques (13) et d'un électrolyte polymère solide (15) placé entre ces électrodes. Les électrodes symétriques, à savoir l'anode et la cathode, sont faites de matériaux tels que du ruthénium, de l'iridium, du cobalt, du zinc, du bismuth, du cadmium, de l'argent, ou leurs oxydes. L'électrolyte polymère solide (15), qui se trouve en contact étroit avec l'anode et la cathode, est fabriqué à partir d'une structure de support polymère, tel que de l'alcool polyvinylique, dans laquelle on a dispersé une espèce chimique active d'électrolyte conducteur de protons.
