Abstract:
A system regulating pressure of a reactor for hightemperature electrolysis or co-electrolysis (HTE) or to an SOFC fuel-cell stack operating under pressure. The operation of the system includes: regulating upstream of one of the chambers, a flow rate of moisture-containing gas DH to guarantee electrochemical stability of a preset operating point; and controlling pressure by virtue of valves arranged downstream of the stack, for regulating gases including the moisture-containing gas, and which are generally hot.
