Abstract
A system for regulating the pressure of a high-temperature electrolysis or co-electrolysis (HTE) reactor or a fuel cell (SOFC) operating under pressure. The operation of the system includes: regulating the DH wet gas flow upstream of one of the chambers so as to ensure the electrochemical stability of the predetermined operating point; regulating the DO gas flow upstream of the at least one second chamber so as to ensure gas scavenging in the at least one second chamber, and in the enclosure; regulating the flow of second gas circulating in the enclosure, downstream of the enclosure, so as to ensure the detection of leaks and safety in relation thereto and to prevent the formation of an explosive atmosphere; and controlling the pressure, by means of the regulation valves arranged downstream of the stack, on the gases, including the wet gas, which are also generally hot.
