Title:
SOLID OXIDE ELECTROLYSIS CELL, AND METHOD AND SYSTEM FOR OPERATING SAME
Document Type and Number:
WIPO Patent Application WO/2020/196236
Kind Code:
A1
Abstract:
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.
