The invention essentially consists in supplying fuel (either steam or a mixture of steam with CO2 or H2 or CH4) to distinct zones of a cell or a group of stacked cells and of an adjacent cell or group of adjacent stacked cells within a given (co-)electrolysis reactor or a SOFC fuel-cell stack.

High-temperature, low-temperature&#x2014;gradient methods for (CO-)electrolysis of water (SOEC) or for producing electricity within a reactor or fuel-cell stack (SOFC) respectively

A heat exchanger can be integrated into an interconnector that can be used in both a SOFC fuel cell and an EHT electrolyser, which allows a heat-transfer fluid different from that in the reactive and drainage gas circuits to be circulated from the inlet of the reactor, thereby allowing the best possible management of the exothermic operating modes of the SOFC cell and the exothermic or endothermic operating modes of the EHT electrolyser and the SOFC cell, especially in the absence of current for the latter.

Method for high-temperature electrolysis or co-electrolysis, method for producing electricity by means of an SOFC fuel cell, and associated interconnectors, reactors and operating methods
