Abstract
An electrolyser for generating hydrogen including a plurality of elementary electrolysis cells including a cathode, an anode, and an electrolyte provided between the cathode and the anode. An interconnection plate is interposed between the anode of an elementary cell and a cathode of a following elementary cell, in electric contact with the anode and the cathode, and includes a cathodic compartment, an anodic compartment for circulation of fluid to the cathode and the anode respectively, and a chamber for collecting a gas generated at the cathode, separated from the cathodic compartment and the anodic compartment by first and second walls respectively, the first wall at least having a thickness allowing diffusion of the gas through the first wall from the cathodic compartment to the chamber.
