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.

System for electrolysing water (SOEC) or fuel-cell stack (SOFC) operating under pressure, the regulation of which is improved

A liquid-to-vapor conversion device includes a chamber having an opening connected to a liquid intake, a pressure relief opening, and a vapor outlet. The device also includes a flow controller arranged at the level of the liquid intake, and a burst disk installed at the level of the pressure relief opening. Further, the device includes pressure-limiting means arranged at the level of the liquid intake. The pressure-limiting means is configured to decrease the flow rate in the liquid intake when the pressure in the liquid intake exceeds a threshold value smaller than a bursting pressure of the burst disk.
