Abstract
(EN)
Provided is a method for operating a solid oxide electrolysis cell capable of suppressing deterioration of hydrogen electrodes. The present invention provides a method for operating a solid oxide electrolysis cell provided with a hydrogen electrode, an oxygen electrode, and an electrolyte layer disposed therebetween. The hydrogen electrode is provided with a catalyst layer formed by dispersing and supporting Ni-containing particles in a porous body of an electron-ion mixed conductive oxide. The method comprises an alternate operation step for alternately repeating a water vapor electrolysis action and a fuel cell action.

L'invention concerne un procédé de fonctionnement d'une cellule d'électrolyse à oxyde solide capable d'éliminer la détérioration d'électrodes d'hydrogène. La présente invention concerne un procédé de fonctionnement d'une cellule d'électrolyse à oxyde solide pourvue d'une électrode à hydrogène, d'une électrode à oxygène et d'une couche d'électrolyte disposée entre celles-ci. L'électrode à hydrogène est pourvue d'une couche de catalyseur formée par dispersion et support de particules contenant du Ni dans un corps poreux d'un oxyde conducteur mixte ions-électrons. Le procédé comprend une étape de fonctionnement alterné pour répéter alternativement une action d'électrolyse de vapeur d'eau et une action de pile à combustible.
