Title
(EN) ELECTROCHEMICAL CELL WITH SINTERED ANODE OF METALLIC PARTICLES AND OXIDES
(FR) CELLULE ELECTROCHIMIQUE PRESENTANT UNE ANODE FRITTEE A BASE DE PARTICULES ET OXYDES METALLIQUES
Abstract
(EN)
Anode (1) for an electrochemical cell and method for the production thereof. This anode consists of a mixture of electron- and ion-conducting particles. The ion-conducting particles consist of oxides. The anode is made up in such a way that that part (3) of anode located close to the electrolyte (2) comprises small oxygen-ion-conducting particles, whilst the part (4) located closer to the current collector comprises coarser oxide particles. By this means it is possible to provide for optimum adaptation to the various requirements which are imposed in respect of the behaviour of the anode located at the electrolyte or at the current collector (6).
(FR)
L'invention concerne une anode (1) destinée à une cellule électrochimique ainsi qu'un procédé de production associé. Cette anode comprend un mélange de particules conductrices d'électrons et d'ions. Les particules conductrices d'ions se composent d'oxydes. On fabrique l'anode de manière que la partie (3) de l'anode située à proximité de l'électrolyte (2) comprenne des petites particules conductrices d'ions oxygène, tandis que la partie (4) située plus près du collecteur de courant comprend des particules d'oxydes plus grossières. De cette manière, on peut adapter de façon optimale les besoins requis relatifs au comportement de l'anode située au niveau de l'électrolyte ou au niveau du collecteur de courant (6).
