Abstract

L’invention concerne une entretoise pour dispositif électrochimique à oxyde solide (200), ledit dispositif (200) comprenant : au moins un interconnecteur (102,104), une cellule électrochimique (106) à oxyde solide disposée entre ledit interconnecteur (102,104) et un autre interconnecteur (102;104), etladite entretoise (202), disposée entre lesdits interconnecteurs (102,104), en particulier, autour de ladite cellule (106) ; caractérisée en ce que ladite entretoise (202) : comporte une couche, dit couche principale, réalisée en un matériau composite à matrice céramique, dit matériau CMC, ou en un précurseur dudit matériau CMC, électriquement isolant ; etest en partie, ou en totalité, étanche au gaz. Elle concerne également un dispositif électrochimique à oxyde solide comprenant une telle entretoise. Elle concerne en outre un système électrochimique à oxyde solide comprenant de tels dispositifs électrochimiques. Voir Figure 2aThe invention relates to a spacer for a solid oxide electrochemical device (200), said device (200) comprising: at least one interconnector (102, 104), a solid oxide electrochemical cell (106) disposed between said interconnector (102, 104) and another interconnector (102, 104), and said spacer (202), disposed between said interconnectors (102, 104), in particular, around said cell (106); characterized in that said spacer (202): comprises a layer, referred to as the main layer, made of a ceramic matrix composite material, referred to as CMC material, or of a precursor of said CMC material, which is electrically insulating; and is partially or wholly gas-tight. It also relates to a solid oxide electrochemical device comprising such a spacer. Furthermore, it relates to a solid oxide electrochemical system comprising such electrochemical devices. See Figure 2a
