Disclosed is a method for the temperature control of an electrochemical system comprising a stack of electrochemical cells and interconnection plates interposed between the electrochemical cells, means for supplying gas to the electrochemical cells and means for collecting gases produced by the electrochemical cells, and means for electrically connecting the system to the outside, wherein the electrochemical device also comprises heating means integrated into the stack, said heating means comprising at least a first and a second heating element, the first heating element being disposed in a first location in the stack and the second heating element being arranged in a second location in the stack, said method comprising steps of: applying a first control command to the first heating element and a second control command to the second heating element, said control commands being configured such that a thermal gradient in the stack in the direction of the stack is maintained substantially at a defined value.

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

A partly oxidized substrate is disclosed. According to one aspect, the substrate is formed by subjecting a substrate made of a porous metal or metal alloy including particles of at least one metal or metal alloy bound by sintering. The substrate includes a first main surface and a second main surface. The porosity of the substrate gradually changes from the first main surface to the second main surface. The substrate is partially oxidized by an oxidizing gas such as oxygen and/or air. A method for preparing the substrate and high temperature electrolyzer (THE) cell including the substrate are also disclosed.
