Abstract
A high-temperature electrolyser including a stack of electrolysis cells in which steam is made to flow both at a cathode and at an anode. The architecture of the electrolyzer is configured to have each cathode inlet end and anode inlet end close to an oxygen, or respectably hydrogen, collection duct portion. With the structure, a buffer volume of steam is created around the oxygen and hydrogen collectors, which therefore constitutes a simple and effective sealing mechanism within the electrolyser.
