Abstract
An electrolysis installation for decomposing water into hydrogen and oxygen comprises: an electrolysis stack; a water recirculation system supplying water to the stack and comprising a circuit and a recirculation pump, first and second separators for separating from water hydrogen and oxygen respectively produced in the stack; a hydraulic supply means supplying the recirculation circuit with deionised water to compensate for water consumed by production of gaseous hydrogen and oxygen, and an extinguishing means for inertising the first and second separators when the installation is shut down, wherein the extinguishing means comprises first and second relief valves provided on the first and second separators, respectively, wherein the valves relieve pressure in the two separators simultaneously while keeping the water level inside the two separators substantially constant, and the extinguishing means controls the supply means to completely fill the two separators with water once the two separators are relieved of pressure.
