WATER VAPOR GENERATOR, FOR ELECTROLYSIS OR WATER CO-ELECTROLYSIS REACTOR (SOEC) OR FUEL CELL (SOFC) HAVING PRESSURIZED OPERATION

摘要

The present invention relates to a device forming a steam generator (GV), for an electrolysis or co-electrolysis reactor or a fuel cell operating under pressure, comprising: a combustion chamber (7) adapted to perform a combustion by auto -inflammation of dry hydrogen (H2) with oxygen (02); a feed pipe (71) for pressurized dry hydrogen, connected to the inlet of the combustion chamber; - A supply duct (72) of dry oxygen under pressure, connected to the inlet of the combustion chamber; an outlet duct (73) for the water vapor generated in the chamber; a thermal barrier (8) arranged inside the chamber, the barrier being adapted to guide the gases H2 and O2 from the chamber inlet to the center of the volume it delimits.
