Abstract
A method for the operation of an SOEC stack reactor (Solid Oxide Electrolyser Cell), according to which, in the absence of electricity, synthesis gas H+CO or a mixture H+COis injected at the cathode inlet of the reactor in such a way as to produce methane inside the reactor. Since the catalytic methanation reaction is exothermic, the stack reactor can therefore be held at temperature, without loss of fuel. The fuel used for the methanation (synthesis gas or hydrogen) can advantageously be that which has been previously produced during the operating phases with available electricity.
